Answer:

about 566.667 or to be exact: 1700/3

Step-by-step explanation:

85 is 15% of what number

We should translate this.

85 = 15% * (some number)

call that number x

85 = 15% *(x)

Solve for x

85 = 0.15 * x

x = 85/0.15 = 1700/3

x = 566.667

Answer:

We have, 15% × x = 85

or,

100

× x = 85

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 85 ×

100

x = 566.67

If f[6} = x ^ -2x , find: f [6} =

ASHA 777 [7]

Answer:

1/ 6^12

Step-by-step explanation:

f[x} = x ^ (-2x)

f(6) = 6 ^ (-2*6)

= 6 ^ -12

We know the negative exponent moves it to the denominator

= 1/ 6^12

What is the image of (6,−3) after a dilation by a scale factor of 1/3 centered at the origin?

attashe74 [19]

Answer:

(2,-1)

Step-by-step explanation:

Multiply everything by 1/3:

6*1/3=2

-3*1/3=-1

This makes it smaller, so you know what the dilation is.

Of all rectangles with area 324324, which one has the minimum perimeter? Let P and w be the perimeter and width, respectively

ra1l [238]

Answer:

For w = 18 units perimeter is minimum

P = 2(18 + w)

Step-by-step explanation:

Given;

Area of the rectangle = 324 units²

P is the perimeter

w is the width

Let L be the length of the rectangle

therefore,

P = 2(L + w) ............(1)

also,

Lw = 324

L = $\frac{324}{w}$ ..........(2)

substituting 2 in 1

P = $2(\frac{324}{w} + w)$

now,

for minimizing the perimeter

$\frac{dp}{dw}=\frac{d(2(\frac{324}{w} + w))}{dw}$ = 0

$2((-1)\frac{324}{w^2}+1)$ = 0

$(-1)\frac{324}{w^2}+1$ = 0

$(-1)\frac{324}{w^2}$ = -1

w² = 324

w = 18 units

For w = 18 units perimeter is minimum

therefore,

from 2

L = $\frac{324}{18}$

L = 18 units

objective function for P is:

P = 2(18 + w)
