Answer:

♡ hi there, madi here! ♡

hope your having a great day.

I did the math so here's your answer.

2x−3)(x−3)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

2x-3=0. x-3=0

Set the first factor equal to 0 and solve.

x=3/2

Set the next factor equal to 0 and solve.

x=3

Therefore, the final solution is all the values that make (2x-3) (x-3)=0 true. x=3/2,3♡

The line with equation a + 4b = 0 coincides with the terminal side of an angle θ in standard position and cos θ>0 . What is t

Nikitich [7]

Answer:

$\frac{-1}{\sqrt{17} }$

Step-by-step explanation

We have given that equation of line a+4b=0

⇒4b= -a

⇒ $b= \frac{-a}{4}$

slope of line = $tan\theta =\frac{P}{B}= \frac{-1}{4}$

⇒ $tan\theta$ is negative therefore it lies into 4th quadrant

By, Pythagoras theorem $H^2=P^2+B^2$

by putting value of P= -1 & B=4

the value of $H=\sqrt{17}$

with the given condition $cos\theta>0$

i.e. $\theta$ ∈ (3π/2, 2π)

now, $sin\theta= \frac{P}{H}= \frac{-1}{\sqrt{17}}$

Describe how the graph of y = x2 can be transformed to the graph of the given equation.

Vikki [24]

<span>1.Describe how the graph of y = x2 can be transformed to the graph of the given equation.

y = (x+17)2

Shift the graph of y = x2 left 17 units.

2.Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = (x-4)2-8

Shift the graph of y = x2 right 4 units and then down 8 units.

.Describe how to transform the graph of f into the graph of g.

f(x) = x2 and g(x) = -(-x)2

Reflect the graph of f across the y-axis and then reflect across the x-axis.

Question 4 (Multiple Choice Worth 2 points)

Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = x2 + 8

Shift the graph of y = x2 up 8 units.

Question 5 (Essay Worth 2 points)

Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.
f as a function of x is equal to the square root of x and g as a function of x is equal to 8 times the square root of x

f(x) = √x, g(x) = 8√x

vertical stretch factor 8

Based on a survey of U.S. residents completed in 2014, ___________ percent of respondents agreed that global warming is occurrin

Daniel [21]

Using the percentage concept, supposing 520 out of 1000 respondents believe in global warming, 52% of respondents agreed that global warming is occurring.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$
