Answer:
Step-by-step explanation:
If f(x)= 9x^2+2x-3, find f(-1).
Answer:
f(-1)= 4
Step-by-step explanation:
Just plug -1 into all Xs
and split it into 2 seperate problems for the time being
[9 times (-1)^2] + [2(-1)-3]
-1 squared is positive 1 times the 9 is just 9
Plus 2 times -1 is -2 minus 3 is -5
combine the two seperate problems you have
9-5 the subtract and
f(-1)= 4
The image of point (-1, 7) under a reflection across the y-axis is (-1, -7). *
True
False
Answer:
False
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(- 1, 7 ) → (1, 7 )
Answer: True
Step-by-step explanation:
Because since it's getting reflected over the Y-axis it's gonna be all negatives.

Three neighbors plan to complete fencing projects this spring. As shown in the diagrams below, Neighbor A plans to fence in his rectangular backyard with a 6-foot tall wooden privacy fence. Neighbor B plans to construct a circular chain link fence around his pool. And, Neighbor C is putting a vinyl fence around three side of his front yard. Note: Diagrams are not drawn to scale. Intended fences are marked with a dashed line.
Answer:
- The neighbor that has the most amount of fence to put up is: Neighbor A.
- The neighbor that has the least amount of fence to put up is: Neighbor C.
Step-by-step explanation:
To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:
Convert yards to feet (Remember that :
To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:
Where r is the radius.
In this case, the radius is:
Substituting, you get:
To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:
Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.
The neighbor that has the least amount of fence to put up is: Neighbor C.
hope this helps btw i just copy and pasted this so its not my work
Answer:
- The neighbor that has the most amount of fence to put up is: Neighbor A.

Answer:
Z= 180 X = 95 y= 147
Step-by-step explanation:
Z=180 because it is a line and when it is a line it = 180 degrees
for X you want to first find the angle of the other triangle and when you do you subtract that # from 180 because those 2 angles make a line
to find that angle next to X is...
180- (the other 2 angles in the triangle)
180- 45- 50
180-95
85 degrees
now do
180-85
95 degrees -- this is what X =
now you want to find the angle that is left in one triangle
so do
180- 95- 52
180- 147
33 degrees -- the angle that was missing
to find Y do...
180- 33
147 degrees -- this is what Y =
Which expression is equivalent to \left(3^{-6}\times 3^{3}\right)^{-1}\normalsize?(3 −6 ×3 3 ) −1 ? 3^{-19}3 −19 3^{18}3 18 3^{-3}3 −3 3^{3}3 3
Answer:
27
Step-by-step explanation:
Given the expression
[tex]\left(3^{-6}\times 3^{3}\right)^{-1}\\[/tex]
According to law of indices, this can be written as;
[tex]\left(3^{-6+3})^{-1}\\\\= (3^{-3})^{-1}\\\\= 3^{-3*-1}\\\\= 3^3\\\\= 27[/tex]
Hence the required answer is 27

At a digital store, Jay paid a total of $31.35 for games and movie rental. He rented 6 games at $3.99 each game and 3 movies.
How much did Jay pay per movie?
$23.94
$3.48
$7.41
$2.47
Answer: 2.47
Step-by-step explanation:
6 times 3.99 is 23.94
31.24 minus 23.94 is 7.30
2.47 times 3 is 7.30
Triangle XYZ has the following values:
m<X = 92 degrees
m<Y =42 degrees
what is the measure of angle Z?
Answer:
46 degrees
Step-by-step explanation:
Total angular measurement for a triangle = 180
180 - 92 - 42 = 46 degrees

52 divided by 6 as a fraction
Answer:
52/6 = 8 and 2/3
Step-by-step explanation:
52 divided by 6 is 8 and 2/3
6 multiplied by 8 is 48
52-48 is 4
so 52/6 is 8 remainder 4
or you can divide 4 by 6
4/6 = 2/3
so it can also be 8 and 2/3
52 divided by 6 as a fraction in its simplest form is 8 2/3.
To express 52 divided by 6 as a fraction, you simply write it as:
52 / 6
To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.
The GCD of 52 and 6 is 2.
Divide both the numerator and denominator by 2:
(52 / 2) / (6 / 2)
This simplifies to:
26 / 3
now, we have,
Divide 26 by 3:
26 ÷ 3 = 8 with a remainder of 2
The whole number part is 8, and the remainder (2) becomes the new numerator.
The denominator remains the same.
So, 26/3 as a simplified mixed number is: 8 2/3
So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

What is the surface area of the three-dimensional figure formed by the net shown?
Answer:
336 cm²
Step-by-step explanation:
1 rectangle 24 cm by 12 cm
1 triangle with base 12 cm and height 8 cm (combining the two small triangles into 1 larger triangle)
SA = 24 cm * 12 cm + 12 cm * 8 cm / 2
SA = 288 cm² + 48 cm²
SA = 336 cm²

Maria wants to know what time it is, but after looking at her analog clock, notices that the numbers are all missing! She notices that the minute hand is pointing straight up, and that the angle measure between the hour and minute hand is 90 degrees. If she knows that the time must be between 1:00 and 5:30, what time is it?
Answer:
3:00
Step-by-step explanation:
If the minute hand is pointing straight up, it means that the time is at an exact hour (ex. 1:00, 2:00, not 1:30, etc.).
If the angle between the hour and the minute hand is 90 degrees, then we know that the time is either 3:00 or 9:00.
However, because the time must be between 1:00 and 5:30, it must be 3:00.

The cost to mail a package varies directly to the weight of the package. If a 14- ounce package costs $4.48 to mail, find the weight of a package that cost $8 to mail.
Answer:
Step-by-step explanation:
Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).
You should get 0.32.
Now just multiply by 8 and you should get your answer. This answer is 2.56.
Answer:
2.56
Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.

The volume of a cylinder is 54π cubic inches and the height is 6 inches. Find the radius.
Answer:
The radius of the cylinder is 3 inches.
Step-by-step explanation:
For any given cylinder, the volume can be expressed as:
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius of its circular surface, and h is its height.
Given that: volume = 54π cubic inches, and the height = 6 inches.
then,
54[tex]\pi[/tex] = [tex]\pi[/tex] x [tex]r^{2}[/tex] x 6
54[tex]\pi[/tex] = 6[tex]\pi[/tex][tex]r^{2}[/tex]
[tex]r^{2}[/tex] = [tex]\frac{54\pi }{6\pi }[/tex]
= 9
r = [tex]\sqrt{9}[/tex]
r = 3
The radius of the cylinder is 3 inches.
