1 answer:

ivolga24 [154]2 years ago

6 0

Answer:
120
Step-by-step explanation:
To estimate the value, you round the digits to the nearest 10 , or the nearest 2 significant figures, in this case, 40.16 is rounded to 40 and 2.970201 is rounded to 3. This gives us 40 * 3 = 120

Elenor and Max used two rectangular wooden boards to make a set for the school play. One board was 6 feet long, and the other wa

Tanzania [10]

Answer:

The width is 5.25 feets

Step-by-step explanation:

The dimensions of the two rectangular wooden boards that Elenor and Max used to make a set for the school play are shown in the attached photo. The widths of the two boards are equal. The lengths are 6 feets and 51/2 feets

Area of each rectangular length, L × Width, W

Area of the longer rectangular board

= 6x W = 6W feet^2

Area of the shorter rectangular board

= 11/2 x W = 11W/2 feet^2

The area of the set is 60-3/8 square feet. This is equal to 483/8 feet^2.

Therefore,

483/8 = 6W + 11W/2 = 23W/2

8 × 23W = 483 × 2

184W = 966

W = 966/184 = 5.25 feets

Find the formula for an exponential function that passes through the two points give.

Ksenya-84 [330]

Answer:

$y=3(2)^{x}$

Step-by-step explanation:

Given.

Two points are given.

$(x, y)=(-1,\frac{3}{2})$ and $(x, y)=(3,24)$

An exponential function is in the general form.

$y=a(b)^{x}$ -------(1)

We know the points $(-1,\frac{3}{2})$ and $(3,24)$

put the first point value in equation 1

$\frac{3}{2}=a(b)^{-1}$

$\frac{3}{2}=\frac{a}{b}$

$a=\frac{3}{2}\times b$ --------(2)

put the second point value in equation 1

$24=a(b)^{3}$ ----------(3)

Put the a value from equation 2 to equation 3

$24=\frac{3}{2}\times b(b)^{3}$

$b^{3+1}=\frac{24\times 2}{3}$

$b^{4} = 16\\b=\sqrt[4]{16} \\b=2$

Put the b value in equation 2

$a=\frac{3}{2}\times 2$

$a=3$

Put the a and b value in equation 1

$y=3(2)^{x}$

So, the exponential function that passes through the points $(-1,\frac{3}{2})$ and $(3,24))$ are $y=3(2)^{x}$ .
