Answer:

A rectangle

Step-by-step explanation:

A cross section parallel to the base of a pyramid will be a similar shape as the base of the pyramid. In this case, a rectangle.

natka813 [3]

Standard quadratic equation .. y = a x^2 + b x + c
parabola 'a' not equal to zero 
a<0 parabola opens downward 
a>0 parabola opens upward 
when |a| >>0 the parabola is narrower 
when |a| is close to zero , the parabola is flatter 

when the constant is varied it only effects the vertical position of the parabola , the shape remains the same

What is the equation of the horizontal asymptote? f(x)=4(52)x+7 y=?

natta225 [31]

ANSWER

y=7

EXPLANATION

The horizontal asymptote of an exponential function

$f(x)= a {(b)}^{x} + c$

is y=c.

The given exponential function is

$f(x)= 4 {(52)}^{x} + 7$

When we compare to

$f(x)= a {(b)}^{x} + c$

c=7, therefore the horizontal asymptote is y=7.

Find the value of k so that 48x-ky=11 and (k+2)x+16y=-19 are perpendicular lines.

Rufina [12.5K]

Answer: k = -1 +/- √769

Step-by-step explanation:

48x - ky = 11

-48x -48x

-ky = -48x + 11

$\frac{-ky}{-k} = \frac{-48x}{-k} + \frac{11}{-k}$

$y =\frac{48x}{k} - \frac{11}{k}$

Slope: $\frac{48}{k}$

*************************************************************************

(k + 2)x + 16y = -19

- (k + 2)x -(k + 2)x

16y = -(k + 2)x - 19

$\frac{16y}{16} = -\frac{(k + 2)x}{16} - \frac{19}{16}$

$y = -\frac{(k + 2)x}{16} - \frac{19}{16}$

Slope: $-\frac{(k + 2)}{16}$

**********************************************************************************

$\frac{48}{k}$ and $-\frac{(k + 2)}{16}$ are perpendicular so they have opposite signs and are reciprocals of each other. When multiplied by its reciprocal, their product equals -1.

$-\frac{(k + 2)}{16}$ * $\frac{k}{48}$ = -1

$\frac{(k + 2)k}{16(48)}$ = 1

Cross multiply, then solve for the variable.

(k + 2)(k) = 16(48)

k² + 2k - 768 = 0

Use quadratic formula to solve:

k = -1 +/- √769
