Answer:
18 weeks
Step-by-step explanation:
We are given the (time, population) pairs (0, 5) and (7, 47). With these values, we can use the two-point form of the equation of a line to write the equation of the linear model.
p = (p2 -p1)/(t2 -t1)(t -t1) +p1
p = (47 -5)/(7 -0)(t -0) +5
p = 6t +5 . . . . . the linear model matching the given points.
For p = 113, the time (number of weeks) is ...
113 = 6t +5
108 = 6t . . . . . . subtract 5
18 = t . . . . . . . . . divide by 6
After 18 weeks, the beetle population will reach 113.

Lena used a total of 3 5/6 gallons of gas while driving her car. Each hour she was driving, she used 7/9 gallons of gas. What was the total number of hours she was driving?
Step-by-step explanation:
3 x 5/6 = 2.5 gallons of gas used
7/9 galllons per 1 hour
Hence if she used 2.5 gallons,
2.5 ÷ 7/9 =
[tex]3 \frac{3}{14} hours[/tex]

Write 1011.1012 in normalized exponential form.
[tex]1011.101_2[/tex] in a normalized exponential form is written as [tex]0.1011101 \times 2 ^4[/tex]
Given the following data:
[tex]1011.101_2[/tex]A normalized exponential form.In Computer technology, binary numbers like decimal numbers in mathematics can be written in an exponential form and it involves the use of powers of two (2) rather than powers of ten (10).
Additionally, all non-zero binary numbers have a unique normalized exponential form and their binary point must always appear before the first one (1) bit, which yields a unique integer (exponent) and a unique mantissa respectively.
Thus, the normalized exponential form for the given binary number is written as follows:

if f(x) = x + 7 and g(x) = 1 / x - 13, whaf is the domain of (f°g)(x)?
Answer: Choice D) x can be anything but 13
========================================================
Explanation:
The domain of [tex](f \circ g)(x) = f(g(x))[/tex] is the same as the domain of g(x)
The domain for g(x) is [tex]\{x|x \ne 13\}[/tex] saying we can plug in any number we want as long as it's not 13. This is to avoid dividing by zero. The same domain applies for the composite function because
[tex]f(x) = x+7\\\\\\f(g(x)) = g(x)+7\\\\\\f(g(x)) = \frac{1}{x-13}+7\\\\\\(f \circ g)(x) = \frac{1}{x-13}+7\\\\\\[/tex]
and we can see that we still need to kick out x = 13 from the domain to avoid the division by zero issue.

The diameter of the sphere will be equal to 4.59 feet.
What is a sphere?
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
Given that:-
The spheres cost $2 per square foot and Selim can spend $20 per sphere. What is the maximum diameter of the spheres he can purchase?The area of the sphere will be = 20 / 2 = 10 square feet
The diameter of the sphere will be calculated as:-
Area = 4 π r
10 = 4 π r
r = 10 / ( 4 π )
r = 0.79 feet
D = 2r = 2 x 0.79 = 1.59 feet
Therefore the diameter of the sphere will be equal to 4.59 feet.

Area of the two triangles:
A = 1/2*b*h
A = 1/2*3*4
A = 1/2*12
A = 6
Area of the two rectangles:
A = bh
A = 4*3
A = 12
Area of square:
A = bh
A = 3*3
A = 9
Now add these numbers together to get total area:

The average salary for a first-year teacher is $27,989. If the distribution is approximately normal with a standard deviation of $3250. If the z-score is 0.34. What salary corresponds to the z-score
If needed, delete the comma and/or the dollar sign.
=========================================================
Work Shown:
mu = 27989 = population mean
sigma = 3250 = population standard deviation
z = (x-mu)/sigma
z*sigma = x-mu
x = z*sigma + mu
x = 0.34*3250 + 27989
x = 29,094
The salary of $29,094 corresponds to the z score of 0.34.
This indicates the salary $29,094 is exactly 0.34 standard deviation units above the mean.

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
we know that in the right triangle ABC
tan function is ratio of opposite side and adjacent side
tan(72°)=h/x
h=xtan(72°) ....... equation 1
In the right triangle ABD
tan(55°)=h/(x+3)
h=(x+3)tan(55°) ..... equation 2
From equation 1 and 2
xtan(72°)=(x+3)tan(55°)
xtan(72°)-xtan(55°)=3tan(55°)
x[tan(72°)-tan(55°)]=3tan(55°)
x=3tan(55°)/[tan(72°)-tan(55°)]
We have to find the value of h
h=xtan(72°)
h=[3tan(55°)*tan(72°)]/[tan(72°)-tan(55°)]
h=8 miles
Hence, the height is 8 miles of the plane.

Find the area of the trapezoid
Answer:
49 units squared
Step-by-step explanation:
The area of a trapezoid is calculated with the following formula:

(3+11) * 1/2 * 7 = 49 the area is stated in square units so the answer is 49^2
Describe how the graph of y = -2(x-4)3 + 1 can be obtained from the graph of y = x3.
I am guessing you meant y=-2(x-4)^3+1 from x^3
From the parent cubic function x^3,
a(x-k)^3+h is its transformation and it would be vertical stretch by a, followed by a horizontal translation by k and vertical translation by h
Your equation follows the same format it has a negative sign at the front before the ( ) which means a reflection over the x axis at the beginning
SO your graph is a
1.reflection over the x axis
2.followed by a vertical stretch by 2
3.followed by a horizonal translation to the right 4
4.followed by a vertical translation up 1

I'm not sure what it means by "define the types of linear" (maybe theres a given function?), but to find the x intercept you need to make y 0. For example:
if we have a function
f(x) = 2x + 1
and we want to find the x intercept we substitute 0 to y
0 = 2x + 1
not
f(0) = ......
Answer:
To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. How do you find the Y intercept in a word problem? When a word problem involves a constant rate or speed and a beginning amount, it can be written in slope-intercept form: y=mx+b.
