Answer:
Martins triangle is a right angled triangle with hypotenuse of 5cm adjacent of 4cm and opposite side of 3cm.Step-by-step explanation:
A triangle that has one of his angles to be 90° is known as a right angled triangle. The triangle has one right angle and two acute angles. The three sides of the triangle are namely the hypotenuse (which is the longest side), the opposite and the adjacent. One of the side of the triangle can be written in terms of the other using the theorem called pythagoras. According to the theorem;
[tex]hyp^{2} = opp^{2} + adj^{2} \\[/tex]
Based on the values of the sides given
hypotenuse = 5cm (being the longest side)
[tex]hyp^{2} = 3^{2}+4^{2} \\ hyp^{2} = 25\\hyp = \sqrt{25}\\ hyp = 5cm[/tex]
This shows that the triangle is a right angled triangle as described by Martin since we are able to express one side in terms of the other.

Find the length of the third side to the nearest tenth.
Answer:
5.3
Step-by-step explanation:
You use the Pythagoras theorem which is a^2+b^2=c^2.
Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.
8^2 - 6^2 = b^2
64 - 36 = b^2
b = sqrt(28)
b = 5.2915.... = 5.3

What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
From the given graph, the coordinate points are (1, 8) and (0, 2)
Using the formula [tex]y=a\times(b)^x[/tex]
Where, a is x-intercept
Substitute, a=2 and (x, y)=(1, 8) in [tex]y=a\times(b)^x[/tex], we get
[tex]8=2\times(b)^1[/tex]
⇒ b=4
Substitute a=2 and b=4 in [tex]y=a\times(b)^x[/tex], we get
[tex]y=2\times(4)^x[/tex]
⇒ [tex]f(x)=2\times(4)^x[/tex]
Therefore, the function for the given coordinates is [tex]f(x)=2\times(4)^x[/tex].

One hour's cost for the trampoline gym will be $12.
What is ratio?The ratio can be defined as the number that can represent one quantity as a percentage of another. They can be compared only when the two numbers in a ratio have the same unit. Ratios are used to compare two objects.
Given, A trampoline gym charges $6 for 1/2 of an hour.
Since,
For 1/2 hour gym charges = 6$
So from the definition of the ratio
Thus,
For 1-hour gym will charge = 6*2
For 1 hour gym will charge = 12$
therefore, One hour cost for the gym will be $12.

Rosa tiene 55 hojas de colores y
les encargo a sus dos sobrinas
Thalía y Paulina que hicieran
paquetes con 6 hojas cada uno.
¿Cuántos paquetes podrían hacer
con 55 hojas?
Answer:
9 packages
Step-by-step explanation:
Each package will have 6 sheets, so to find the number of packages for 55 sheets, we can just use a rule of three:
1 package -> 6 sheets
x packages -> 55 sheets
x * 6 = 55 * 1
x = 55 / 6 = 9.17
Rounding down, we have x = 9 packages.
So it can be done a total of 9 packages, and there will be (55 - 9*6) = 1 sheet left.
Una catedral esta situada en la cima de una colina. Cuando la punta de su torre se observa desde el ple de la loma, el angulo de elevacion es de 48°. Cuando se ve desde un punto a una distancia de 6096 m del pie del promontorio, el angulo de elevacion es de 41° la cuesta de la colina forma un angulo de 32° Aproxima la altura de la catedral
Answer:
La altura de la catedral es de 15119,97 m.
Step-by-step explanation:
Para una respuesta única, la pregunta se formula de la siguiente manera:
Una catedral se encuentra en la cima de una colina. Cuando se ve la parte superior de su torre desde la parte inferior de la colina, el ángulo de elevación es de 48 °. Cuando se ve desde un punto a 6096 m del pie del promontorio, el ángulo de elevación es de 41 °, la pendiente de la colina forma un ángulo de 32 ° Se aproxima a la altura de la catedral
Deje que la base de la colina = C
El punto 6096 m de la base = A
La cima de la catedral = B
∴ ∠A = 41 °
∠C = 180-48 = 132 °
∠B = 180 - (41 + 132) = 7 °
[tex]\dfrac{6096}{sin7} = \dfrac{CB}{sin41}[/tex]
∴ CB = 32816.59 m.
Punto E = Base de la catedral.
Punto D = Punto debajo de la base de la catedral al nivel del pie de la colina
Por lo tanto, la altura de la catedral = BE
∡ABE = 90-41 = 49 °
∡CED = 90-32 = 58 °
∴ ∡CEB = 180 - 58 ° = 122 °
De la regla seno tenemos;
[tex]\dfrac{CB}{sin(\angle CEB)} = \dfrac{BE}{sin(\angle ECB)}[/tex]
∠EBA = 90 - 48 = 42°
∠EBC = 42 - 7 = 35°
∠ECB = 180 - 35 - 122 = 23°
[tex]\therefore \dfrac{32816.59 }{sin(122)} = \dfrac{BE}{sin(23)}[/tex]
[tex]BE = \dfrac{32816.59 }{sin(122)} \times sin(23) = 15119.97 \ m[/tex]
La altura de la catedral = 15119,97 m.

Line AB is tangent to circle O at B. Find the length of the radius r for AB = 8 and AO = 11.7. Round to the nearest tenth if necessary. The diagram is not to scale.13.7, 3.7, 8.5, 14.2
Answer:
8.5
Step-by-step explanation:
So the line segment that is tangent to the circle is 8, and AO is 11.7.
When you connect them, they are perpendicular, so you have a right triangle with one unknown leg that we will call X, a leg that is 8, and a hypotenuse that is 11.7.
If you use the Pythagorean Theorem, you will find that the leg is √72.89, which is approximately 8.5.
That leg is the radius.
This might be wrong so check it.
