1. You must apply the following formula:

LA=1/2 ×(Perimeter of the base)(Slant length)

2. The slant length is (By the Pythagorean Theorem):

a^2=b^2+c^2

a= b^2+c^2

a=√(1^2+3^2)

a=√10

3. The perimeter of the base is:

P=2+2+2+2

P=8

4. Then, you have:

LA=1/2 ×(Perimeter of the base)(Slant Length)

LA=1/2 ×(8)(√10)

LA=(8√10)/2

LA=4√10

Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15

schepotkina [342]

Answer:

30 to 48, 40/64

Step-by-step explanation:

Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.

For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is equal.

For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are not equal.

For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is equal.

For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is not equal.

Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it won't be equal.

Find the zeros of the function y = -4x^2 + 16

adoni [48]

$-4x^2+16 & =0\\\\\implies -4(x^2-4) & =0 \\\\\implies x^2-4 =0\\ \\\implies x^2-2^2 =0\\\\\implies (x+2)(x-2)=0\\\\\implies x=2,~~x = -2$

Due to its weakening steel industry, Clay County has been experiencing population decline of 3% every year. The current populati

wel

Using an exponential function, it is found that the population of Clay County will be of $13,482.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

A(0) is the initial value.

r is the growth rate, as a decimal.

In this problem, the current population is 10,300 people, with a growth rate of 3%, hence A(0) = 10,300 and r = 0.03.

The equation is given by:

$A(t) = A(0)(1 + r)^t$

$A(t) = 10300(1 + 0.03)^t$

$A(t) = 10300(1.03)^t$

Hence, in 10 years, the population will be given by:

$A(10) = 10300(1.03)^{10} = 13842$
