Answer:
(x)=(x-7)(x-4)
g(x)=x(2)+7x - 2
Now find a common denominator. (x+10)(x-4) is a good one.
x-16/(x+10)(x-4)+x-4/(x+10)(x-4)
2x-20/(x+10)(x-4)
The value of function g(f(-1)) is -70.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
The value of functions,
f (x) = -4x - 7
g (x) = x² + 7x - 2
Now, Value of function g(f(-1)) as;
g(f(x)) = g(-4x - 7)
= (-4x - 7)² + 7(-4x - 7) - 2
= (4x + 7)² + 7 × -4 × x - 7 × 7 - 2
= 16x² + 49 + 56x + 28x - 49 - 2
= 16x² + 84x - 2
Thus, g(f(x)) = 16x² + 84x - 2
Now, To find value of g(f(-1)) we can substitute x = -1,
g(f(-1)) = 16(-1)² + 84(-1) - 2
= 16 - 84 -2
= -70
Thus, The value of function g(f(-1)) is -70.

A metal shop is cutting a rectangular piece of sheet metal with a width of 60 inches and a length of 144 inches. The shaded parts of the diagram represent two rectangular sections, A and B, that will be cut and removed.
Part A :What are the dimensions of section B?
Part B:What will be the area, in square inches, of the piece of sheet metal after both sections are cut and removed?
Answer:
Dimensions of section B = 36 inches, 48 inches
Area of the piece of sheet metal after both sections are cut and removed = 6336 square inches
Step-by-step explanation:
Given: Width and length of a rectangular piece of sheet metal are 60 inches and 44 inches.
To find: dimensions of section B, the area of the piece of sheet metal after both sections are cut and removed
Solution:
Length of rectangle B = TR = SR - ST = PQ - ST (As SR = PQ being opposite sides of rectangle)
Length of rectangle B = PQ - ST = 60 - 24 = 36 inches
Breadth of rectangle B = UR = QR - QV - VT - TU
Here, QR = PS = 144 inches (opposite sides of rectangle PQRS are equal )
QV = 36 inches
VT = WX = 24 inches ( opposite sides of rectangle WVTX are equal)
TU = 36 inches
So,
Breadth of rectangle B = 144 - 36 - 24 - 36 = 48 inches
Area of rectangle B = length × breadth = 36 × 48 = 1728 square inches
Area of rectangle WVTX = length × breadth = 24 × 24 = 576 square inches
Area of rectangle PQRS = PQ × PS = 60 × 144 = 8640 square inches
Area of the piece of sheet metal after both sections are cut and removed =8640 - ( 1728 + 576 ) = 8640 - 2304 = 6336 square inches

Se tiene un lote baldío de forma triangular bardeado. La barda de enfrente tiene una medida de 4 m,las otras dos bardas no es posible medirlas directamente pues hay mucha basura. Sin embargo,se sabe que el ángulo que está frente a la barda frontal mide 34° y otro de sus ángulos mide 64°. Se quiere calcular la medida de la barda que está enfrente del ángulo de 64°. Explica por qué no es posible resolver el problema aplicando sólo las razones trigonométricas o el teorema de Pitágoras
Answer:
a) La medida de la barda que está enfrente del ángulo 64° es de, aproximadamente, 6.4292m. b) El triángulo en cuestión no es un triángulo rectángulo, es decir, ninguno de sus ángulos internos es recto (90 grados sexagesimales). En estos casos, no se puede aplicar el Teorema de Pitágoras o la simple utilización de las razones trigonométricas; se aplican, en cambio, leyes para la resolución de triángulos oblicuángulos (o triángulos no rectángulos).
Step-by-step explanation:
Este problema no se puede resolver "aplicando sólo las razones trigonométricas o el teorema de Pitágoras" porque es sólo aplicable a triángulos rectos, es decir, uno de los ángulos del triángulo es recto o igual a 90 grados sexagesimales. Los dos restantes triángulos suman 90 grados sexagesimales, o se dice, son complementarios.
La resolución de triángulos que no son rectos (conocida en algunos textos como solución de problemas de triángulos oblicuángulos) pueden resolverse usando, la ley de los senos (o teorema del seno), ley de los cosenos y la ley de las tangentes. El caso propuesto en la pregunta se ajusta a la ley de los senos:
[tex] \\ \frac{a}{\sin(\alpha)} = \frac{b}{\sin(\beta)} = \frac{c}{\sin(\gamma)}[/tex]
Es decir, la razón entre el lado de un triángulo y el seno del ángulo que tiene frente a él es igual para todos los lados y ángulos del triángulo.
El triángulo de la pregunta no tiene un ángulo recto
La suma de los ángulos internos de un triángulo es de 180 grados sexagesimales:
[tex] \\ \alpha + \beta + \gamma = 180^{\circ}[/tex]
En la pregunta tenemos que la suma de los dos ángulos propuestos es:
[tex] \\ 34^{\circ} + 64^{\circ} + \gamma = 180^{\circ}[/tex]
[tex] \\ 98^{\circ} + \gamma = 180^{\circ}[/tex]
Restando 98 grados sexagesimales a cada lado de la igualdad:
[tex] \\ 98^{\circ} - 98^{\circ} + \gamma = 180^{\circ} - 98^{\circ}[/tex]
[tex] \\ 0 + \gamma = 180^{\circ} - 98^{\circ}[/tex]
[tex] \\ \gamma = 82^{\circ}[/tex]
Con lo que se deduce que no hay ningún ángulo recto en el triángulo propuesto y no se podría usar el Teorema de Pitágoras o simples razones trigonométricas para resolverlo.
Resolución del lado del triángulo
De la pregunta tenemos:
La barda de enfrente tiene una medida de 4m. El ángulo que está enfrente de esta barda (barda frontal) es de 34°. No se sabe el valor del lado que está enfrente del ángulo de 64°, pero se puede calcular usando la Ley de los senos.Digamos que:
[tex] \\ a = 4m, \alpha = 34^{\circ}[/tex]
[tex] \\ b = x, \beta = 64^{\circ}[/tex]
Entonces, aplicando la Ley de los senos:
[tex] \\ \frac{a}{\sin(\alpha)} = \frac{b}{\sin(\beta)}[/tex]
Multiplicando a cada lado de la igualdad por [tex] \\ \sin(\beta)[/tex]
[tex] \\ \frac{a}{\sin(\alpha)}*\sin(\beta) = \frac{b}{\sin(\beta)}*\sin(\beta)[/tex]
[tex] \\ \frac{a}{\sin(\alpha)}*\sin(\beta) = b*\frac{\sin(\beta)}{\sin(\beta)}[/tex]
[tex] \\ \frac{a}{\sin(\alpha)}*\sin(\beta) = b*1[/tex]
[tex] \\ \frac{a}{\sin(\alpha)}*\sin(\beta) = b[/tex]
Sustituyendo cada valor en la expresión anterior:
[tex] \\ b = \frac{a}{\sin(\alpha)}*\sin(\beta)[/tex]
[tex] \\ b = \frac{4m}{\sin(34^{\circ})}*\sin(64^{\circ})[/tex]
[tex] \\ b = 4m*\frac{0.8988}{0.5592}[/tex]
[tex] \\ b = 6.4292m[/tex]
En palabras, la medida de la barda que está enfrente del ángulo 64° es de, aproximadamente, 6.4292m.
El lado c puede obtenerse de manera similar considerando que [tex] \\ \gamma = 82^{\circ}[/tex].

i need to find the value of x
Answer:
x = 24
Step-by-step explanation:
Since all the angles share a common vertex 'U' lying on a straight line QT.
Therefore, sum of all angles formed at U will be equal to 180°.
m∠RUQ + m∠RUS + m∠SUT = 180°
(2x - 4) + (3x + 5) + (2x + 11) = 180°
(2x + 3x + 2x) + (5 - 4 + 11) = 180
7x + 12 = 180
7x = 180 - 12
x = [tex]\frac{168}{7}[/tex]
x = 24
Therefore, value of x = 24
Sarah picks two hats at random from 5 bill caps and 3 beanies. What is the probability she picks a BILL cap, DOES NOT REPLACE IT, then chooses ANOTHER BILL cap?
Answer:
The probability is 5/14
Step-by-step explanation:
Here, we are to calculate/estimate a probability
Firstly , we need to know the total number of caps
we have 5 bill caps and 3 beanies.
Total number of caps = 5 + 3 = 8 caps
The probability of picking the first bill cap is 5/8
Now after removing this and not replacing, we have 4 bill caps left and 3 beanies
Total cap remaining is 7 caps while the probability of picking a bill cap now is 4/7
The combined probability is thus 5/8 * 4/7 = 5/14

Quando colocamos roupas molhadas no varal em dias quentes percebemos que as roupas depois de um tempo ficam secas. Qual o estado físico que se encontra nas roupas molhadas? e nas roupas secas?
Answer:
Liquid water to vapor waterStep-by-step explanation:
This problem is about our wet clothe, when we put it under the Sun to dry.
Notice that the clothe is wet at the beginning, but after a certain time, it gets dry. This phenomenon is beacuse the change of the state of the water inside the clothe.
You see, at the beginning, the water is in liquid state making the wet effect, then that water transforms into vapor, makign the dry effect.
Therefore, the answer is "liquid water to vapor water", that's the change.

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking an even number and then picking an even number?
Simplify your answer and write it as a fraction or whole number.
1/6 and you got the comment why
Answer:
1/6
Step-by-step explanation:
Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

The Capacity of a container will ALWAYS be less than the containers Volume
Answer:
The correct option is Sometimes.
Step-by-step explanation:
Volume refers to the amount of three-D space that a liquid, a solid or a gas, occupies. Some of the most commonly used units of volume are cubic meters, liters, millilitres and cubic centimetres.
Whereas, capacity refers to the capability to hold or absorb something. It is similar in theory to volume, but there are little dissimilarities.
Consider the example below:
The nitrogen gas cistern has a capacity of 12 gallons. The gas in the experiment expanded to three times its original volume.So, the capacity of a container can be or cannot be less than the volume.
Thus, the correct option is Sometimes.

You have an ice cream scoop with a 2-inch diameter. You have an ice cream cone with a 2-inch diameter and a height of 5 inches. If you place one scoop of ice cream on the cone and let the ice cream melt, will it spill over the cone?
Answer:
No, because the volume of the cone is greater than the volume of the ice cream scoop.
Step-by-step explanation:
To solve this problem we just need to compare the volume of the ice scream scoop with the volume of the ice cream cone.
The ice scream scoop is a sphere with a diameter of 2 inches (so a radius of 1 inch), then the volume is:
V = (4/3) * pi * r^3
V = (4/3) * pi * 1^3
V = 4.1888 in3
Now, to find the volume of the ice cream cone, we just need to use the formula of the cone volume (with radius = 1 inch):
V = (1/3) * pi * r^2 * h
V = (1/3) * pi * 1^2 * 5
V = 5.236 in3
As the volume of the cone is greater than the volume of the ice cream scoop, the ice cream will not spill over the cone after melting.
