Answer:
∠ FGE = 52.5°
Step-by-step explanation:
The secant- secant angle is half the difference of the measures of the intercepted arcs, that is
∠ FGE = [tex]\frac{1}{2}[/tex] (arc BD - arc FE )
= [tex]\frac{1}{2}[/tex] × (135 - 30)°
= [tex]\frac{1}{2}[/tex] × 105°
= 52.5°

f(x) = x2. What is g(x)?
Answer: C
Step-by-step explanation:
f(x) = x²
g(x) has the same vertex as f(x) but is wider so has a vertical stretch by a factor of (1/3).
g(x) = (1/3)x²

D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is m∠DEF?
Answer:
m∠DEF is 90°
Step-by-step explanation:
It is given that D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. Thus, using the distance formula, we have
⇒
⇒
and
⇒
⇒
Also,
⇒
⇒
Now,
⇒
⇒
Thus, Pythagoras theorem holds.
Hence, m∠DEF is 90°⇒ΔDEF is right angled triangle which is right angled at E.
DE^2 = 1 + 16 = 17.
EF^2 = 16 + 1 = 17.
DF^2 = 9 + 25 = 34.
Since (DE)^2 + (EF)^2 = (DF)^2,
angle E is 90 degrees.
DF must be the hypotenuse

Use the graph of f to describe the transformation that results in the graph of g. f(x) = log x; g(x) =
Hey there!
Answer:
2nd choice, The graph of g(x) is the graph of f(x) reflected in the x-axis, expanded vertically by a factor of 5, and translated 8 unit(s) down.
Step-by-step explanation:
Recall that the transformation form of a logarithmic function is:
y = ±alog(b(x-h))+k
Given g(x) = -5logx-8:
Negative in front of equation: reflection over the x-axis
'a' value of 5: expanded vertically by a factor of 5
'k' value of -8: translated 8 unit(s) down.
What are the constants in the expression below? Select three options.

-8
-3.7
1/3
x
12
Answer:
12, -3.7, ⅓
(2nd, 3rd and 5th option)
Step-by-step explanation:
Constants are numbers without any variables with it.
x and y are the variables here.
-8 is the coefficient of y and hence it is not a constant.
*the value of a constant will not change
Note that the constant includes the symbol too, hence it is -3.7 and not 3.7.

A department store sells logo shirts at an original price of $20.
Answer:
Answer is below.
Step-by-step explanation:
Macy forgot that a discount of 25% means the cost is multiplied by 75%.
Take the original price of the shirt, $20, times 75% for each month and times 50% for the employee discount.
20 x 0.75 x 0.75 x 0.50 = $5.63 is the price of the shirt for the employees using all of the discounts.
Which best describes the relationship between the line that passes through the points
Answer:
Neither perpendicular nor parallel.
Step-by-step explanation:
To find the answer, you just need to find the slopes of each line.
The slope of the line with points at (-6, 5) and (-2, 7) would be (7 - 5) / (-2 + 6) = 2 / 4 = 1/2.
The slope of the line with points at (4, 2) and (6, 6) would be (6 - 2) / (6 - 4) = 4 / 2 = 2.
They are most definitely not the same line.
They are not perpendicular, either, since although they are [eek I forgot the term for it] opposites, they are both positive. To be perpendicular, one slope must be negative and the other positive.
They are not parallel, since the slopes are not the same.
So, the relationship between the lines are that they are neither parallel nor perpendicular.

Find the total surface area of this square based
pyramid.
Answer:
125
Step-by-step explanation:
Surface area is the total area of all the surfaces of a shape. In order to calculate the surface area we need to consider each unique face individually.
The base of the pyramid is a square of side-length 5, and its area is 5×5=25
The side faces form an iscosoles triangle of height 10 and base length 5, its area is 10×5×[tex]\frac{1}{2}[/tex]=25.
The total surface area = Triangle +Triangle +Triangle +Triangle +Square = 25+25+25+25+25 = 125

Whích quadratic inequality does the graph below represent?

wa-
5-32
12

5
2
Answer:
The third option
Step-by-step explanation:
first, you can eliminate the 2nd and the 4th option because the vertex of the graph is located at -3, and not 3. The reason it is not the 1st option is, because of the greater than or equal to sign, this inequality actually shows the white area.
Therefore, leaving the 3rd option. The y-intercept is correct, it is -3. The sign is also correct, because on the axis of the quadratic, -3 is the highest possible y-intercept. So y has to be less than or equal to -3.

Lindsey lives 32 blocks from the grocery store. It takes her 9 minutes to walk 12 blocks. If she continues to walk at the same rate, how long would it take her to walk 32 blocks?
Answer:
if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks
Step-by-step explanation:
i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks

BRAINLIEST!!! Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It took Mary 25 seconds longer to come down than to go up. How many steps does the Old Tower have?
Answer:
The old tower has 65 steps.
(I think,)
Answer:
150 steps
Step-by-step explanation:
For every 6 steps going up it takes a extra 1 second to go down. Since it took Mary 25 seconds longer to get down you multiply 6 by 25 and you'll get 150 steps.

A group of students must collect at least $160 to organize a science fair. They have already collected $20. Which graph best represents the possible amounts of money the students still need to collect? (1 point) Number line graph with closed circle on 160 and shading to the right. Number line graph with closed circle on 140 and shading to the right. Number line graph with closed circle on 20 and shading to the right Number line graph with closed circle on 180 and shading to the right.
Answer:
Number line graph with closed circle on 20 and shading to the right or c
Step-by-step explanation:
This is the best answer because you start of at 20 dollars and need to continue collecting money till you have 160 dollars.
Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.
this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)
Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)
