Answer:

13.5

Step-by-step explanation:

$3*(7+2)/\sqrt{4}$

You use PEDMAS - priority of calculation

1) Paranthesis

2) Exponents

3) Divide or Multiple (whichever comes first, reading left to right)

4) Add or Subtract (whichever comes first, reading left to right)

so,

<u>Parenthesis first:</u>

$7+2=9$

becomes

$3*9/\sqrt{4}$

<u>No exponents, so we skip this step</u>

<u>Left to right for multiply or divide: first comes multiply.</u>

<u /> $3*9 = 27$

becomes

$27/\sqrt{4}$

<u>Now, last one is divide:</u>

<u /> $27/\sqrt{4} = 27/2 = 13.5$

P - parenthesis

O - Order

D - Division

M - Multiplication

A - Addition

S - subtraction

==============

$\dashrightarrow \sf 3 * (7+2) \ \div \ \sqrt{4}$

$\dashrightarrow \sf 3 \ * \ 9\ \div \ \sqrt{4}$

$\dashrightarrow \sf 3 \ * \ 9\ \div \ 2$

$\dashrightarrow \sf 3 \ * \ 4.5$

$\dashrightarrow \sf \ 13.5$

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is y + 7 = (x – 10). What is the stan

Crank

Answer:

Step-by-step explanation:

We are given coordinates of the line passed through (–5, –1) and (10, –7) .

Applying slope formula,

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

$\left(x_1,\:y_1\right)=\left(-5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:-7\right)$

Therefore,

$m=\frac{-7-\left(-1\right)}{10-\left(-5\right)}$

$m=-\frac{2}{5}$

Therefore, slope is $m=-\frac{2}{5}$ .

Applying point-slope form $y-y_1=m(x-x_1),$ we get

$y+7 = -\frac{2}{5}(x-10)$

$y+7=-\frac{2}{5}(x-10)$

On multiplying both sides by 5, we get

$5(y+7)=5\times-\frac{2}{5}(x+1)$

5y+35=-2(x-10)

5y+35=-2x+20

Adding 2x on both sides, we get

5y+25+2x=-2x+20+2x

2x+5y+35=20

Subtracting 35 from both sides, we get

2x+5y+35-35=20-35

2x+5y=-15.

Therefore, required equation is :

Select the correct answer Consider functions p and q. p(x) = log₂ (x - 1) g(x) = 2^x - 1 Which statement is true about these fun

goldenfox [79]

The x-intercept of p(x) is x = 2, the x-intercept of g(x) is x = 0, then the correct option is B.

<h3>What can we say about the x-intercepts of the given functions?</h3>

For a function f(x), the x-intercept is the value of x such that:

f(x) = 0.

Here we have:

p(x) = log₂(x - 1)

Remember that:

logₙ(1) = 0

For any base n, then the x-intercept of p(x) is x = 2, because:

p(2) = log₂(2 - 1) = log₂(1) = 0.

The other function is:

g(x) = 2ˣ - 1

Remember that any number to the power of zero is equal to 1, then:

g(0) = 2⁰ - 1 = 1 - 1 = 0

The x-intercept of p(x) is x = 2, the x-intercept of g(x) is x = 0, then the correct option is B.

Isosceles trapezoid ABCD has legs If AB = 6y – 3, BC = 4y – 5, and CD = 7y – 18, find the value of y

castortr0y [4]

Answer:

The value of y is y=15

Step-by-step explanation:

We have:

AB = 6y – 3, BC = 4y – 5, and CD = 7y – 18

We define the isosceles trapezoid as it has two opposites parallel, the two other opposites legs are equal and also the diagonals are equal.

Here AB = CD

6y-3 = 7y-18

Combine the like terms:

18-3 = 7y-6y

15 = y

It means the value of y is y=15....

A couple of college students frustrated with the current class registration process decide to survey 500 random students on camp

aleksklad [387]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Standard deviation = $\sqrt{(n*p)(1 - p)}$

Substitute the values in:

$\sqrt{(500 *0.84)(1-0.84)}$ = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.
