Answer:

0.25

Step-by-step explanation:

we have

$(-0.5)^2$

we know that

$-0.5=-\frac{1}{2}$

substitute

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

Remember that

$(-1)(-1)=1\\(-1)(1)=(-1)$

$(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25$

Type the missing numbers in this sequence: -99, -97, -93, -89, -87

iragen [17]

Answer:

Hope I helped ꒰⁎˃ ॢꇴ ॢ˂⁎꒱

Step-by-step explanation:

-99, -97, -93, -89, - 87

Lets look at the differences

+2, +4, +4, +2

Doesn't really seem like a specific pattern, but I can assume it goes like +2, +4, +4, +2, +4, +4, +2, +4, +4,

We are on +4 then, so the answer would be (-87)+4, which is -83

This sequence follows no pattern though, so if there is an option that there is not enough info to solve the sequence, pick that.

A given rectangle is twice as wide as it is tall. It has a perimeter of 138 inches. How many inches tall is it? How many inches

oee [108]

Length = x
width = 2x
perimeter = 138in

in order to find perimeter you add length and width twice, so;

2(2x + x) = 138
2(3x) = 138
6x = 138
x = 23

since x = 23;

the length is 23in and the width is 46in

The population at Bishop High School is 2000 students in 2011. Every year the population decreases by 50 students

Artemon [7]

Answer:

Let p be the population at t be the number of years since 2011. Then, $p=2000-50t$

The projected population of the high school in 2015=1800
In 2019 the population be 1600 students

Step-by-step explanation:

Given: The population at Bishop High School students in 2011 =2000

Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.

So, the function is a linear function.

Let p be the population at t be the number of years since 2011.

Then, $p=2000-50t$

So at t=0, p=2000

In year 2015, t=4, substitute t=4 in the above equation ,we get

$p=2000-50(4)\\\Rightarrow\ p=2000-200\\\Rightarrow\ p=1800$

Hence, the projected population of the high school in 2015=1800

Now, put p=1600 in the function , we get

$1600=2000-50t\\\Rightarrow50t=2000-1600\\\Rightarrow50t=400\\\Rightarrow\ t=\frac{400}{50}\\\Rightarrow\ t=8$

Now, 2011+8=2019

Hence, in 2019 the population be 1600 students
