Answer:
4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9
Nancy drew a scale drawing of a theater. In the scale Nancy used for the drawing, 1 inch represents 3 feet. The stage is 16 inches long in the drawing. How long in feet is the actual stage?
Answer:
The answer to this question is 48 feet
Step-by-step explanation:
You would see that 1 inch is 3 feet then you would multiply 3 and 16 to receive 48
In a survey of 100 people, some of them jog for exercise, some of them ride a bike, some do both, and 15 do not jog or ride a bike. If 46 of the people surveyed job and 21 of them both jog and ride a bike, how many of the people surveyed only ride a bike?
Answer:
Bike alone = 39
Step-by-step explanation:
Given that:
Total number = n(T) = 100
Jog= n(J)
Bike = n(B)
Bike and jog = n(BnJ) = 21
Number who jog = 46
Jog alone = 46 - 21 = 25
Neither jog nor bike = 15
Let bike alone = x
Hence,
Jog alone + bike alone + jog and bike + none of the two = 100
25 + x + 21 + 15 = 100
x = 39

Heather made $299 for 13 hours of work.
At the same rate, how much would she make for 18 hours of work?
Answer:
$414
Step-by-step explanation:
We know that Heather made $299 for 13 hours of work.
So, to find how much Heather will make for 18 hours of work at the same rate, we can write and solve for the following proportion:
[tex]\frac{299}{13}=\frac{x}{18}[/tex]
Notice that we align the rates vertically and the measurements horizontally (dollars in the numerator and hours in the denominator).
So, to find how much Heather will make for 18 hours, we will solve for x. Cross-multiply:
[tex]13x=5382[/tex]
Divide both sides by 13:
[tex]x=\$414[/tex]
So, Heather will make $414 for 18 hours of work.
And we're done!
Please help! I am supposed to write a recursive and an explicit function for the geometric sequence but this one is really frustrating me. Thank you!
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.
a₁ = 1
aₙ = 4 aₙ₋₁
The explicit formula is:
aₙ = 1 (4)ⁿ⁻¹
Which is the point-slope equation of a line with a slope of 1/2 that contains (4,7)
My answer choices are
A= Y - 7 = 1/2 (x+4)
B= Y - 7 = 1/2 (x-4)
C = Y - 7 = - 4 + (1/2)
D = y + 7 = 1/2 (x+
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (4, 7) , thus
y - 7 = [tex]\frac{1}{2}[/tex](x - 4) → B

+6x+12, determine the average rate of change of the function over the interval -3\le x \le 5−3≤x≤5.
Answer:
4
Step-by-step explanation:
edge
The average rate of the function is 4.
What is average rate of function?The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,
A(x) = (change in outputs) / (change in inputs)
= Δy / Δx
= [f(b) - f(a)] / (b - a)
given function:
f(x) = -x² + 6x + 12
Now,
let a= -3, b = 5
and, f(b)= -(5*5) + 6*5 + 12
=-25+ 30 +12
= 17
f(a) = -(- 3 * (-3))+6(-3) +12
= -9-18+12
= -15
Now,
f(b)- f(a) / (b-a)
=17 -(-15))/5-(-3)
=32/ 8
=4

Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.
Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a functionThe horizontal line test is used to show that the function has an
inverse or not
If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverseLet us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.

coordinate plane with points at A 0 comma 2 and B 2 comma 0 intersected by line f Dilate line f by a scale factor of 3 with the center of dilation at the origin to create line f'. Where are points A' and B' located after dilation, and how are lines f and f' related? A) The locations of A' and B' are A' (0, 2) and B' (6, 0); lines f and f' intersect at point A. B) The locations of A' and B' are A' (0, 6) and B' (2, 0); lines f and f' intersect at point B. C) The locations of A' and B' are A' (0, 2) and B' (2, 0); lines f and f' are the same line. D) The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel.
Answer:
D (0,6) (6,0)
Step-by-step explanation:
when you multiply it you do the x coordinates first then the y.
so (0,2) x 3 = (0,6)
(2,0) x 3 = (6,0)
These coordinates are parralel to each other.
The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel, the correct option is D.
What is Transformation?Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.
Dilation is a process in which the object or the graph is enlarged or compressed by a scale factor.
The coordinates of A( 0, 2)
The coordinates of B(2,0)
The scale factor is 3
The center of dilation of f is at the origin to create line f'.
The points A and B lie on the line f, when line f is dilated, the coordinates will also get dilated.
The coordinate of A after dilation is 3 * (0,2)
A' = (0,6)
The coordinate of B after dilation is 3 * (2,0 )
B' = (6,0)
The line f' will be parallel to the line f.

Wally's grandmother started a college savings account for him with
$3,000. What is the total amount of money in the account after 5 years if
the annual simple interest rate is 3%?
I need this plz help explain the proses thx ASAP
Answer:
$450
Step-by-step explanation:
You want to calculate the interest on $3000 at 3% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $3000.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 3000 × 0.03 × 5 to get that:
The interest is: $450.00
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 3000.00 + 450.00 = 3450.00.
