Answer: -3 bc the exponent is adding -1 each time
Answer: -3 for the exponent box
Step-by-step explanation: Hi there! Let's get started.
We know that a negative exponent is going to decrease by a power of 10 every time for example 10 x 10^-1 = 1 because the -1 says we need to move the decimal point one to the left.
So with this we take 2.345 x 10^-3 = 0.002345.
We moved the decimal point 3 to the left from 2.345 to get 0.002345.
Hope this helps! :)

Use the figure. Identify a segment skew to GH
Answer:
the answer is BE
Step-by-step explanation:
skews are lines that dont intersect or arent parallel to each other
in that case BE or CF are correct but BE is the only answer choice that works... hope it works
The line segment skew to GH is BE.
What are skew line segments?Skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.
Given is a rectangular prism, with vertices, A, B, C, D, E, F, G and H
We are asked to identify a line segment which is skew to GH,
In the given options, EF, AD are BC are parallel to GH hence not skew, but line segment BE is neither parallel nor perpendicular to GH.
Hence, the line segment skew to GH is BE.

Mrs. Smith bill at red lobster was $42.20 before tax. The sales tax was $2.21 and mrs smith also included in $8 tip. How much money did she spend at red lobster?
Answer: $52.41
Step-by-step explanation:
Cost before tax = $42.20
Sales tax = $2.21
Tip = $8
The total amount spent by Mrs Smith at Red Lobster will be:
= Cost before tax + Sales tax + Tip
= $42.20 + $2.21 + $8
= $52.41

If f(x)=13x3−4x2+12x−5 and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is
The correct format of the question is
If f(x)= [tex]\frac{1}{3}x^3 -4x^2+12x -5[/tex] and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is
Answer:
The absolute maximum value of the function F(x) occurs when x is 9
Step-by-step explanation:
F'(x) = [tex]x^2 -8x +12= 0[/tex]
= (x-6)(x-2) = 0
x = 2,6
so we have boundary points 0 , 9 and 2,6
The value of function at these four points
x = 0 2 6 9
F(x) = -5 17/3 -5 22
So the absolute maximum value of the given function is x = 9 and F(x) is 22.
The absolute maximum value of the function f occurs when x is 9 and this can be determined by differentiating f(x) and then equating it to zero.
Given :
[tex]\rm f(x)=\dfrac{1}{3}x^3-4x^2+12x-5[/tex]The domain is the set of all x such that 0≤x≤9In order to determine the absolute maximum value of function f(x), differentiate f(x) and then equate it to zero.
[tex]\rm f'(x)=\dfrac{1}{3}\times(3x^2)-8x+12[/tex]
Now, equate the above equation to zero.
[tex]x^2-8x+12 = 0[/tex]
Factorize the above quadratic equation.
[tex]x^2-6x-2x+12=0[/tex]
x(x - 6) - 2(x - 6) = 0
(x - 6)(x - 2) = 0
Now, determine the value of f(x) at x = 0, 2, 6, 9
f(0) = -5
f(2) = 1/3.(8) - 4(4) + 12(2) - 5
f(2) = 17/3
f(6) = 72 - 144 + 72 - 5
f(6) = -5
f(9) = 243 - 324 + 108 - 5
f(9) = 22
So, the absolute maximum value of the function f occurs when x is 9.

This equation shows how the length of Rob's essay depends on the number of hours he spends writing this week. p = h + 11 The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Rob have to spend writing this week in order to have written a total of 16 pages?
Answer:
Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.
Step-by-step explanation:
From the information given, you can use the formula p=h+11 and solve for h. Then, you have to replace p with 16 to get the amount of hours that Rob will have to spend writing this week in order to have written a total of 16 pages:
p=h+11
h=p-11
h=16-11
h=5
According to this, the answer is that Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.

For a class of students, the association between GPA and SAT math score is roughly linear. The
equation of the least-squares regression line relating y=SAT math score to x = GPA is û = 410.54 + 67.3x. Predict the SAT math score for Jessica, who has a 3.00 GPA.
Answer:
612.44
Step-by-step explanation:
Given the linear regression equation between SAT score and GPA
y = 410.54 + 67.3x
Where
y = SAT math score ; x = GPA
THE SAT math score for Jessica who has a GPA of 3.00
x = 3
y = 410.54 + 67.3(3)
y = 410.54 + 201.9
y = 612.44

At a candy store, you can buy pre-filled bags of candy that weigh 2 1/4 pounds for $8. At this same rate, how much would a 4 pound
bag of candy cost?
Answer:
$14.22Step-by-step explanation:
step one:
given data
we are told that 2 1/4( 2.25 pound) of candy cost $8
let us find the cost of 1 pound first
so
2.25 pound cost #8
1 pound will cost x
cross multiply
x=8/2.25
x=$3.55 for one pound.
step two:
Hence if 1 pound cost $3.55
4 pound will cost = 3.55*4= $14.22

17 What are the x-intercept to the function f(x)=2x-31+2 ?
A {0}
B{-5/2,5/2}. C{ } D{-5/2,-1/2}
Answer:
See below
Step-by-step explanation:
It seems to be a typo.
[tex]f(x)=2x-31+2[/tex]
[tex]f(x)=2x-29[/tex]
The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.
[tex]0=2x-29[/tex]
[tex]x=\dfrac{29}{2}[/tex]
Once there are alternatives with two values, your function is probably a quadratic function.
[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.
