Answer:
The correct answer is A to the 6th power, A^6
Step-by-step explanation:
First, apply the exponent rule. (a^b)^c = a^bc
You would get a^2*3 (* means times) (^ means to the power)
Second refine.
You would get A^6.

write the resulting function if the transformation f(x+3)+9 is applied on the function f(x)=x^2+1
a) x^2+13
b)x^2+19
c)x^2+6x+19
d)x^2+3x+13
Answers
f (x) = x ^ 2 + 1
We apply the transformation f (x + 3) +9:
g (x) = (x + 3) ^ 2 + 1 + 9
Rewriting we have:
g (x) = (x + 3) * (x + 3) + 1 + 9
g (x) = (x ^ 2 + 3x + 3x + 9) + 1 + 9
g (x) = (x ^ 2 + 6x + 9) + 1 + 9
g (x) = x ^ 2 + 6x + 9 + 1 + 9
g (x) = x ^ 2 + 6x + 19
Answer:
the resulting function if the transformation f (x + 3) +9 is applied on the function f (x) = x ^ 2 + 1 is:

Mica is solving for the zeros of a quadratic function by completing the square. Her work is shown. What error did Mica make?
ANSWER CHOICES
Mica should have set each x = 0 instead of f(x).
Mica should have added 2 to 3 instead of 1.
Mica should have multiplied both sides by 2 instead of dividing.
Mica should have subtracted 1 from both sides instead of adding.
Answers
Answer:
Mica should have added 2 to 3 instead of 1.
Step-by-step explanation:
f(x) = 2x^2 – 4x – 3
0 = 2x^2 – 4x – 3
Mica added 3 on boths sides and factored out 2
3 = 2(x^2 – 2x)
We have 2 outside the parenthesis , so we multiply 1 with 2 and add it one left side
3 + 1 = 2(x^2 – 2x + 1) Error in this step
The above step becomes 3 + 2 = 2(x^2 – 2x + 1)
Mica should have added 2 to 3 instead of 1.
What is 60% of 60? need help with this one can some one show me how to do it?
Answers
60 x 0.6 = 36
If we wanted to do it another way, we could multiply 60 by 0.5 and 0.1 seperately and add those numbers up.
[tex]\dfrac x{60}=\dfrac{60}{100}=60\%[/tex]
Multiply both sides by 60, so that
[tex]\dfrac{60x}{60}=\dfrac{60^2}{100}\implies x=\dfrac{3600}{100}=36[/tex]
Another way of doing it: you can easily find that 10% of 60 is 6. Then 60% would be 6 times 10%, and 6 times 6 is 36.

Solve the triangle. A=44 degrees, a = 7,b=8
Answers
Explanation:
1) Use the law of sines:
sin(A) sin(B)
----------- = --------- =>
a b
2) Solve for B:
sin(B) = b * sin(A) / a = 8 * sin(44°) / 7 = 0.79389528
=> B = arcsin(0.79389528) = 52.55°
3) A + B + C = 180° => C = 180° - A - B = 180° - 44° - 52.55° = 83.45°
4) Use the law of sines again:
sin(A) sin(C)
------------- = -------------
a c
5) Solve for c:
c = sin(C) * a / sin(A) = sin(83.45°) * 7 / sin(44°) = 10.0
Answer: a = 7, b = 8, c = 10.
The circle above has a radius of 9 cm. What is the area of the circle?
(Use PI = 3.14)
Answers
answer: 254.469
On this exercise is given that the radius of the circle is 9 cm and it is asked to find its area and use 3.14 as the value of π. Therefore, to find the area of the circle you should substitute the value of the radius and the value of pi into the formula A=πr^2.
A=πr^2
A=(3.14)(9)^2
A=(3.14)(81)
A=254.34
The area of the circle is 254.34 cubic centimeters.
A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area of the kite.
Answers
Height of the kite is = 36 inches.
Width of the kite is = 30 inches
One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .
Now we will use the formula [tex]area=\frac{1}{2}*base*height[/tex] to find the area of each triangle. Then we will add both the areas to find the area of the kite.
Area of 1 triangle = [tex]\frac{1}{2}*36*15[/tex] = 270 square inches
Area of the 2nd triangle is also = 270 square inches
Hence, area of the kite = 270+270 = 540 square inches
The area of the kite is 540 square inches
The dimension of the rectangle is given as:
Height = 36 inches. Width = 30 inches
The area of the kite is then calculated using:
[tex]Area = \frac 12 \times (Height \times Width)[/tex]
Substitute values for Height and Width
[tex]Area = \frac 12 \times (36 \times 30)[/tex]
Evaluate the expression in bracket
[tex]Area = \frac 12 \times 1080[/tex]
Evaluate the product
[tex]Area = 540[/tex]
Hence, the area of the kite is 540 square inches

As viewed from a cliff 340 ft above sea level a ship is 450 feet from the shore what is the angle of depression from the cliff to the ship on the water below
Answers
To get the angle of depression we use the formula:
tan x=opposite/adjacent
where x is the angle of elavation
opposite is the height of the cliff
adjacent is the distance of the ship from the shore
thus
tan x=340/450
tan x=34/45
x=arctan 34/45
x=37.07
hence the angle of elevation= angle of depression=37.1°

Which function represents a line with a slope of −4 and a y-intercept of −2?
A) y = 4x − 2
B) y = −4x + 2
C) y = −4x − 2
D) y = −2x − 4
Answers
Answer:
C) [tex]y = -4x - 2[/tex]
Step-by-step explanation:
The general equation of a line in the xy plane is as follows:
[tex]y = mx + b[/tex]
where [tex]m[/tex] is the slope of the line, and [tex]b[/tex] is the intercept with the y axis.
In this case we want a line with a slope of -4, therefore:
[tex]m = -4[/tex]
and we also want a y-intercept of -2, so:
[tex]b = -2[/tex]
Substituting in the general equation of the straight line:
[tex]y = mx + b[/tex]
⇒[tex]y = -4x-2[/tex]

The museum of science in boston estimated that 64% of all visitors came from within the state. on sunday, 2,500 people attended the museum. how many attended the museum from out of state?
Answers
Percentage of visitors who come from outside will be (100-64)=36%
The total number of attendees is 2500
the total number of of people who came from outside the state will be:
36/100×2500
=900 visitors
First, calculate the number of attendees from within the state by multiplying the total by 64% to get 1,600 people. Subtract this from the total to find the number of out-of-state attendees, 900 people.
Explanation:This is a problem of percentage utilization and subtraction. First, we must determine the number of in-state attendees by multiplying the total number of attendees (2500 people) by the given percentage of in-state visitors (64%).
So, 2500 people x 0.64 = 1600 people.
These are the people who attended from within the state. To find out how many visitors came from out of state, we subtract this number from the total: 2500 people - 1600 people = 900 people. Therefore, 900 people attended the museum from out of state on Sunday.

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates over the next several months. Drake is planning to take the class 6 weeks from now, so he plans to save $125 each week. Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470. He knows that he must adjust his plan in order to meet his goal. Drake came up with the following options: Option A: Stay with saving the original amount each week but take the class a week later than originally planned. Option B: Increase the amount of money he saves each week by $15 from his original plan. Which of the following is a true statement? a. Only option A will allow him to meet his goal. b. Only option B will allow him to meet his goal. c. Both options A and B will allow him to meet his goal. d. Neither option A nor option B will allow him to meet his goal.
Answers
answer- C
total money required = 750
total money saved = 470
weeks left = 2
money earned in each week = 125
money earned in 2 weeks = 250
470 + 250 = 720( so, drake is short of 30 )
option A- by postponing the classes for 1 week, he will earn 125 more, so it is an option to meet his goal as 125>30
option B- by increasing the savings by 15 for two weeks, he will save 30 more which is the amount drake needs. so , it is also a good option
The result of rounding the whole number 53,679,012 to the nearest millions place is: 53,000,000. 50,000,000. 53,600,000. 54,000,000.
Answers
Final answer:
The number 53,679,012 rounded to the nearest million is 54,000,000. The digit in the hundred thousands place determines whether to round up or down. In this case, since it's a 6 (which is >= 5), we round up.
Explanation:
Rounding Whole Numbers to the Nearest Million
To round the whole number 53,679,012 to the nearest million, we need to look at the digit in the hundred thousands place, which is 6. Since this digit is 5 or greater, we round up. Therefore, we increase the digit in the millions place by one, giving us 54,000,000 as the rounded number to the nearest million.
For example, consider another number like 52,700,000. Using the same rounding principle, since the digit in the hundred thousands place is 7, which is greater than 5, we would round up to 53,000,000.
When rounding large numbers, the key is to look at the digit immediately to the right of the place value you are rounding to. If this digit is 5 or higher, you round up, and if it is 4 or lower, you round down.
