$\sqrt{75} + \sqrt{3} + \sqrt{75} + \sqrt{3}$ is the problem. First you find the square root of 75 which is 8.7.
Next you find the square root of 3 which is 1.7
Then you add 8.7x2 + 1.7x2
8.7x2=17.4 and 2x1.7=3.4.
Last step, you add them togather and your answer is 20.8

What is the surface area of the triangular prism?

TiliK225 [7]

Answer:

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 24 ft.

h = 9 ft.

s1 = 15 ft.

s2 = 15 ft.

s3 = 24 ft.

L = 40 ft.

<u>plugin values into the formula:</u>

A = 24*9 + 40(15 + 15 + 24)

= 216 + 40(54)

= 2,376 ft²

#1. Joseph wants to find the side length of a square that has an area of 150

adell [148]

Answer:

The answer is irrational

Step-by-step explanation:

we know that

The area of a square is given by the formula

$A=b^2$

where

b is the length side of the square

In this problem we have

$A=150\ ft^2$

substitute in the formula

$b^2=150$

take the square root both sides

$b=\sqrt{150}\ ft\\$

simplify

$b=5\sqrt{6}\ ft$

Remember that

A <u><em>Rational Number</em></u> is a number that can be made by dividing two integers

The length side is not a integer

therefore

The answer is irrational

A chemistry professor suspects that there is a relationship between the number of classes a student misses and that student’s sc

Airida [17]

Answer:

Interference for regression

Explanation:

Interference for regression is the most suitable statistical test to use to find out if there is any link between number of missed classes and the final test scores.

Because those two variables are related and student test score can be predicted using number of classes that are missed.

Function 1: y = 4x + 5

rosijanka [135]

Answer:

Option B is correct

Function 1, because the slope is 4 and the slope of function 2 is 2.

Step-by-step explanation:

Slope-intercept form:

The equation of line is given by:

$y=mx+b$

where, m is the slope and b is the y-intercept

As per the statement:

Function 1: y = 4x + 5

On comparing with [1] we have;

Slope of function 1 = 4

Function 2: The line passing through the points (1, 6) and (3, 10).

Using slope formula:

$\text{Slope}= \frac{y_2-y_1}{x_2-x_1}$

Substitute the given points we have;

$\text{Slope}= \frac{10-6}{3-1}$

⇒ $\text{Slope}= \frac{4}{2}$

Simplify:

⇒ $\text{Slope}=2$

⇒ $\text{Slope}= \frac{4}{2}$

⇒ Slope of the function 2 is, 2

Since, function 1 is greater rate of change.( i.e 4 > 2)

Therefore,

Function 1 has the greater rate of change, because the slope is 4 and the slope of function 2 is 2.

Solving fp<br> Algebra 2<br> I do not understand how to solve this, could someone please explain?

Olenka [21]

$f(x) = \sqrt{x + 2}$
What's The Fixed Point? Well, Let's Assume X=0, this is our point.

$f(0) = \sqrt{0 + 2} \\ f(0) = \sqrt{2} \\ this \: is \: our \: fixed \: point \: \\ (0, \sqrt{2} )$
OR

$f(p) = \sqrt{p + 2} \\ \\ or \: \sqrt{x + 2} = 0 \\ ( \sqrt{x + 2} ) ^{2} = {0}^{2} \\ x + 2 = 0 \\ x = - 2$
I'm unaware of the nature of the question, so here are some different ways a fixed point is found based on the merits of the question.
