5. x2 – 10x + 21 = 0

Answer: 1/8

Step-by-step explanation:

From the question, we are informed that a large hose can fill 7/8 of a water tank in one hour while a small hose

can fill 3/4 of a water tank in one hour.

To get the solution to the question above, we have to find the difference between the amount if water filled by the large and the smaller hose. This will be:

= 7/8 - 3/4

= 7/8 - 6/8

= 1/8

Answer:

This is an exponential function

Step-by-step explanation:

f(x)=2(3)^x is one example of the exponential function.  Since f(0) = 2(1) = 2, the y-intercept is (0, 2).  The x-axis is the horizontal asymptote.  The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I.  Next time, please be more specific about what you'd like to know.

Answer:

sin2θ = - [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

Given

cosθ = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex] and in fourth quadrant

Then this is a 3- 4- 5 triangle with opposite side = 4

sinθ < 0 in fourth quadrant, then

sinθ = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]

Using the double angle identity for sine

sin2θ = 2sinθcosθ

          = 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex] = - [tex]\frac{24}{25}[/tex]

Answer:

10x=y

Step-by-step explanation:

Divide your outputs by your inputs. In other words, divide 20 by 2, 50 by 5, and 70 by 7. These all equal 10. Therefore, 10 times x will equal y.

Answer:

the 2nd one is -2/2 so the equation would be y=-2/2x+4 the 1st it's kinda blurry it fades away.... but for the 1st one the y- int. is 2 so it would be

y= slope x +2

Answer:

64 + c = 120

Step-by-step explanation:

120 - 64 = 56 t therefore c = 56

The inequality to represent the number of cans, c, that Xander must still collect is c  ≥ 55.

Given the information in the question, the least number of cans that Xander can collet is 120. He can collect more than 120 cans. Thus, the inequality sign to be used is the greater than or equal to sign - ≥.

The number of cans Xander must still collect = 120 - 64 = 55

The inequality solution is c  ≥ 55

Given:

The figure of a right angle triangle.

To find:

The length of the line segment AC.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

In the given right triangle ABC,

[tex]\tan (A)=\dfrac{BC}{AC}[/tex]

[tex]\tan (55^\circ)=\dfrac{BC}{AC}[/tex]

[tex]\tan (55^\circ)=\dfrac{15}{AC}[/tex]

[tex]AC=\dfrac{15}{\tan (55^\circ)}[/tex]

On further simplification, we get

[tex]AC=\dfrac{15}{1.428148}[/tex]

[tex]AC=10.503113[/tex]

[tex]AC\approx 10.5[/tex]

The length of side AC is equal to 10.5 m .

Therefore, the correct option is A.

Answer:

Tax= $4.176 = $4.18

Step-by-step explanation:

Giving the following information:

She adds up the prices listed on the menu for everything they ordered and gets a subtotal for $48.

Tax rate= 8.7% = 0.087

To calculate the Tax, we need to use the following formula:

Tax= total spend*tax rate

Tax= 48*0.087

Tax= $4.176 = $4.18

Answer:

x= -5

x = -5

Answer:

Para convertir una fracción en un decimal, dividimos el numerador entre el denominador. Si tenemos un número mixto, el número natural se mantiene a la izquierda del punto decimal.

Answer:

Aqui esta la respuesta

Step-by-step explanation:

The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

La línea de una fracción que separa el numerador y el denominador se puede reescribir usando el símbolo de división. Entonces, para convertir una fracción en decimal, divide el numerador por el denominador. Si es necesario, puede usar una calculadora para hacer esto. Esto nos dará nuestra respuesta como decimal.

Answer:75

Step-by-step explanation: 50+55 =105,

180-105=75

Subscribe to Offxcial Prxmiise

Answer:

x = 105°

Step-by-step explanation:

First to get to know the last angle of the triangle:

[tex]55 + 50 + x = 180 \\ x = 75[/tex]

The last angle of the triangle is 75°

To get the opposite angle we take 180° (the full angle) minus 75° which results in 105°

Answer:

x = 10

angle top = 118°

angle bottom = 62°

Step-by-step explanation:

6x + 2 + 11x + 8 = 180

17x + 10 = 180

17x = 170

divide both sides by 17.

x = 10

plug in the 10 to each equation to get the number for the angle

6(10) + 2 = 62°

11(10) + 8 = 118°
