use transformation of the parent graph of the m(x)=sqrt(x) to sketch the graph of p(x) = -sqrt(x)-3
Answers
First we need to look at the change of signal of the function (it changes from √x to -√x).
This change of signal means the function was reflected over the x-axis.
Then, the value of -3 was added to the function.
An addition of -3 in the function means a translation of 3 units down.
So the transformations from m(x) to p(x) are:
A reflection over the x-axis followed by a translation of 3 units down.

[tex]y=x+1[/tex]The points (−7,−4) and (3,8) are the endpoints of the diameter of a circle. Find the length of the radius of the circle.
Answers
The length of the radius of the circle is √61.
Here there are two endpoints of the circle (-7,-4) and (3,8)
To find the length between the two points we have a formula:
length = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1} )^{2} }[/tex]
So here we have
([tex]x_{1} , y_{1}[/tex]) = (-7, -4)
([tex]x_{2} , y_{2}[/tex]) = ( 3,8)
Putting the value we have,
[tex]\sqrt{(3 -(-7)^{2} + ( 8-(-4)^{2} }[/tex]
=[tex]\sqrt{10^{2} + 12^{2} }[/tex]
=[tex]\sqrt{100+ 144}[/tex]
=√244
=2√61
The diameter is 2√61
radius = diameter/2
= 2√61/2
= √61
Therefore the length of the radius of a circle is √61.

The measure of angle m∠CGE is 83°
Given,
∠AGF = 62°
∠DGB = 35°
Since, ∠DGB is vertically opposite angle of ∠CGA
Then, ∠CGA = 35°
And also,
∠AGF is vertically opposite angle of ∠EGB
Then, ∠EGB = 62°
Now, we know that CD is straight line
Using angle - sum property,
Then,
∠CGE + ∠EGB + ∠CGA = 180°
Putting the values we get
∠CGE + 62° + 35° = 180°
∠CGE + 97° = 180°
∠CGE = 180° - 97°

Directions - Graph the following slope intercept equation:y=2/3x-2
Answers
Answer
Explanation
The best way to plot graphs, especially straight line graphs, is to use the intercepts. The intercepts are the point(s) that the graph of the function crosses or touches the x and y axis.
The equation is
y = (2/3)x - 2
when x = 0,
y = (2/3)x - 2
y = (2/3)(0) - 2
y = 0 - 2
y = -2
The first point on the graph is (0, -2)
when y = 0,
y = (2/3)x - 2
0 = (2/3)x - 2
(2x/3) = 2
Cross multiply
2x = (2) (3)
2x = 6
Divide both sides by 2
(2x/2) = (6/2)
x = 3
The second point on this graph is (3, 0)
So, the two points are (0, -2) and (3, 0)
We can then easily plot this graph by marking out those two points on the graph and connect the two points for the equation of that line.

Answers
The value of "y" that satisfies the given conditions is -8.
The first straight line passes through two points. The coordinates of the two points are (−4, 9) and (4, 3). The second straight line passes through two points. The coordinates of the two points are (−8, 1) and (4, y).
We know that the first line is parallel to the second line. Hence, the slope of both the lines must be equal.
The slope of the first line is :
m1 = (3-9)/[4-(-4)]
m1 = -6/8
m1 = -3/4
The slope of the second line is :
m2 = (y-1)/[4-(-8)]
m2 = (y-1)/12
We know that m1 = m2.
-3/4 = (y-1)/12
y = -8

Answers
Given:
Car uses 1.6 gallons to go 32 miles
Let's find the amount of gallons of gas the car needs to travel 420 miles.
Here, the relationship between the miles driven and the amount of gas needed is direct variation.
Since it is a direct variation, we have the variation equation when y varies directly with x:
y = kx
Where k is the constant of variation.
Hence, we have:
32 = 1.6k
Let's solve for k.
Divide both sides by 1.6:
[tex]\begin{gathered} \frac{32}{1.6}=\frac{1.6k}{1.6} \\ \\ 20=k \\ \\ k=20 \end{gathered}[/tex]The constant of variation is 20.
The equation that represents this situation is:
y = 20x
Therefore, to find the amount of gallons of gas needed if the car travels 420 miles, substitute 420 for y and solve for x.
420 = 20x
Divide both sides by 20:
[tex]\begin{gathered} \frac{420}{20}=\frac{20x}{20} \\ \\ 21=x \\ \\ x=21 \end{gathered}[/tex]Therefore, the car needs 21 gallons of gas

How long does it take the airplane to hit the water?
Answers
According to the problem, the function f(x) represents the height of the airplane, and x is the time in seconds since the airplane was thrown.
C.The graph shows the zeros x = -1 and x = 4, however, the positive zero is the only one that makes sense to the problem because time can't be negative. So, the zero x = 4 means that the paper airplane will reach the water level after 4 seconds.
D.As we said, just the positive zero has meaning to this situation because, in real life, time is not negative.
Therefore, just one zero (x=4) has real-world meaning.
E.According to the zero x = 4, the paper airplane will hit the water after 4 seconds.

90 marbles in a bag represent three colors of the US flag there are three times as many red marbles as white marbles there are twice as many blue marbles as white marbles find the number of marbles for each color you select one marble at random from the bag find the probability you picked a red or blue marble
Answers
For the given question.
US flag has to be made by total 90 marbles.
Let the number of white marbles be 'x'.
Red marbles are three times the white marble = '3x'.
Blue marbles be twice of white marble = '2x'.
Total marbles = white marble + red marble + blue marble
90 = x + 2x + 3x
6x = 90
x = 15
White marble = 15.
Blue marble 2x = 2×15 = 30.
Red marble 3x = 3×15 = 45.
Probability = favourable outcomes /total outcome
The probability for picking red marble = 45/90 = 1/2.
The probability for picking blue marble = 30/90 = 1/3.
Probability (red or blue) = 1/2 × 1/3
Probability (red or blue) = 1/6
Thus, the probability for picking red or blue marble is 1/6.
