The cost (c) of renting a truck for $30 and then paying $2 per mile (m). Write the function rule

r-ruslan [8.4K]

Answer:

f(x) = 2m + 30

Step-by-step explanation:

Since the truck costs 30 dollars to rent plus the 2 dollars per mile to find the function rule you use an equation that makes the 2 dollars per mile the dependent variable.

On a coordinate plane, 2 lines intersect at (negative 1, 5). Which appears to be the solution to the system of equations shown i

Doss [256]

(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.

Which equations represent the asymptotes of the hyperbola (x-1)^2/36-(y-2)^2/64=1 ?

allochka39001 [22]

Answer:

$4x+3y=10$ and $4x-3y=-2$

Step-by-step explanation:

The asymptote equation of a translate hyperbola with equation $\frac{(x-h)^2}{b^2}-\frac{(y-k)^2}{a^2}=1$ is $y=\pm\frac{b}{a}(x-h)+k$

The given hyperbola has equation: $\frac{(x-1)^2}{36}-\frac{(y-2)^2}{64}=1$

Or $\frac{(x-1)^2}{6^2}-\frac{(y-2)^2}{8^2}=1$

Comparing to $\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1$

We have a=6 and b=8, h=1 and k=2.

We substitute this values to get:

$y=\pm\frac{6}{8}(x-1)+2$

$y=\pm\frac{4}{3}(x-1)+2$

$3y=\pm4(x-1)+6$

We split the plus or minus sign to get:

$3y=4x-4+6$

$3y=4x+2$

$3y-4x=2$

$3y=-4(x-1)+6$

$3y=-4x+4+6$

$3y+4x=10$

Answer: approximately 311 feet

I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.

=========================================================

Explanation:

Refer to the diagram below. When using the 47 degree as the reference angle, we know that,

opposite side = x
hypotenuse = 325

We can say:

sin(angle) = opposite/hypotenuse

sin(47) = x/425

425*sin(47) = x

x = 425*sin(47)

x = 310.825323188148

x = 311

The kite is approximately 311 feet off the ground.

In a triangle ABC if angle a = 60 °,angle<br> b= 60° then find c

Mkey [24]

c = 60

Step-by-step explanation:

A triangle is a figure that has sum of all angles equals to 180

i.e ,

Angle A + Angle B + Angle C = 180

60 degree + 60 degree + Angle C = 180

Angle C = 180 - 60 - 60

Angle C = 60
