110÷4= 27.5 (One hundred ten, divided by four, equals twenty seven, point five; or twenty seven and a half).

20 POINTS AND BRAINLIEST!! Write an exponential function in the form y=ab^x

Rudik [331]

Answer:

$y=13(4)^x$

Step-by-step explanation:

We have the exponential function of the form:

$y=ab^x$

And it goes through the points (0, 13) and (3, 832).

Hence, when we substitute in 0 for x, we should get 13 for y. Therefore:

$13=ab^0$

Since anything to the zeroth power is 1, this yields:

$a=13$

So, we determined that the value of a is 13.

So, our function is now:

$y=13b^x$

We will need to determine b. We know that y equals 832 when x is 3. Hence:

$832=13(b)^3$

Divide both sides by 13:

$b^3=64$

Take the cube root of both sides:

$b=4$

Hence, our b value is 4.

Therefore, our entire equation is:

$y=13(4)^x$

Write an equation of a line in point-slope and slope intercept form that passes through the point (1, -8) and is perpendicular t

prisoha [69]

Answer:

11y-2x= -90

Step-by-step explanation:

for the point (1,-8)

x=1 and y= -8

for the equation,

2x -4y= -11

x= -1/m

m= -1/x

x = -1/ (-11/2 )

m= 2/11

so for the equation,

y-y1= m(x- x1)

y- -8=2/11(x-1)

11(y+8)= 2(x-1)

11y +88= 2x-2

11y-2x= -90

The escalator rises 25° from the ground and a vertical distance of 42 feet. How much horizontal distance does the escalator cove

zvonat [6]

Tangent (25) = opp / adj = 42 / horizontal distance
horizontal distance = 42 / tangent (25)
horizontal distance = 42 / 0.46631
horizontal distance = 90.068838326435200 
horizontal distance = 90.1 feet
