h(x)=x2-5x+7 find when 1-3h(-8)
Answer:
The value of the expression is -332.
Step-by-step explanation:
We are given the following function:
[tex]h(x) = x^2 - 5x + 7[/tex]
We have to solve the following expression:
[tex]1 - 3h(-8)[/tex]
The numeric value at x = -8 is:
[tex]h(-8) = (-8)^2 - 5(-8) + 7 = 64 + 40 + 7 = 111[/tex]
The expression is:
[tex]1 - 3h(-8) = 1 - 3(111) = 1 - 333 = -332[/tex]
The value of the expression is -332.

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 70 square feet. Find the length of the rectangle.
Answer:
The length of the rectangle (l) = 10 cm
The width of the rectangle (w) = 7 cm
Step-by-step explanation:
Step(i):-
Let 'x' be the length of the rectangle
Given that the width is 3 feet shorter than the length
The width of the rectangle = x -3
Area of the rectangle = length × width
Step(ii):-
Area of the rectangle = length × width
= x ( x-3)
Given that the area of the rectangle = 70 square feet
x ( x-3) = 70
⇒ x² - 3x - 70 =0
⇒ x² - 10 x + 7 x - 70 =0
⇒ x (x -10) +7( x-10) =0
⇒ ( x+7) ( x-10) = 0
⇒ x =-7 and x=10
Final answer:-
we choose x=10
The length of the rectangle (l) = 10 cm
The width of the rectangle (w) = 7 cm
Jim and Joyce are saving for their annual vacation. They are going to Hawaii and their plane Tickets costs $2418 total. They have saved 1804 so far. If they are able to save $55 per week. how many weeks of saving will it take before they have saved at least S2418?
Answer:
12 Weeks.
Step-by-step explanation:
2418 minus 1804 is 614.
614 divided by 55 is 11.1, and you can't have 11.1, so you round to 12.
So 12 is therefore your answer.

Maggie stacked a box that was 83 centimeters (cm) tall on top of a box that was 128 centimeters. How tall was the stack of boxes in meters and centimeters?
Answer:
211 centimeter ; 2.11 meter
Step-by-step explanation:
Given that:
Height of box 1 = 128 cm
Height of box 2 = 83 cm
Stacking box 2 on the box 1 :
Height of stack :
Height of box 1 + height of box 2
128 cm + 83 cm = 211 cm
Converting 211 cm to meter :
100 cm = 1 m
211 cm = (211 / 100) m
= 2.11 meter
Lucy separates a number of paintbrushes, x, into 2 equally sized groups. She claims that this is the same as making a group 1/2 the size of his original group. Create an equation that models Lucy's claim.
Answer:
x/2 = 1/2x
Step-by-step explanation:
# of paintbrushes/ 2 piles = 1/2 # of paintbrushes
Answer:
x/2
Step-by-step explanation:
Since Lucy is taking the paintbrushes, x, and splitting them into 2 equally sized groups we can assume that this IS 1/2 the size of the original group.
We can show this claim by simply doing this equation: x/2, since she is splitting them into 2 groups that are equally sized, we are just dividing x by two.

A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 9 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month
Answer:
27
Step-by-step explanation:
9 crew members complete a job in 3 months
Number of crew members is inversely proportion to construction time :
Let :
Crew members = m
Construction time = t
m α 1 /t
m = k/t
m = 9 ; t = 3
9 = k /3
k = 27
If t = 1 (one month)
m =?
m = k/t
m = 27 / 1
Hence;
m = 27 * 1
m = 27 workers

Which graph represents the function f(x)=5lnx?
Answer:
The first graph (top-left) is the correct graph.
Please, also check the attached graph.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=5\:lnx[/tex]
First, we should determine the x and y-intercepts.
Determining the y-intercept:
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
Thus,
substitute x = 0 in the function
y = lnx
y = ln(0)
y = undefined
Therefore, at x = 0, the value of y becomes undefined.
Hence, None is the y-intercept.
Determining the x-intercept:
We know that the value of the x-intercept can be determined by setting y = 0 and determining the corresponding value of x.
Thus,
substitute y = 0 in the function
0 = ln(x)
Flipe the equation
ln(x) = 0
Solve algorithm
ln(x) = 0
Take exponent of both sides
[tex]\:e^{ln\left(x\right)}=e^0[/tex]
[tex]x\:=e^0[/tex]
[tex]x = 1[/tex]
Thus, the point of x-intercept is: (0, 1)
Conclusion:
Now, if we carefully check the graph options, we can easily figure out that the first graph (top-left) correctly displays the x and y-intercepts.
It is clear from the graph that:
at x = 0, y is heading towards -ve infinity.
at y = 0, x = 1
Therefore, the first graph (top-left) is the correct graph.
Please, also check the attached graph.

(3 a ^2 + 2 g^4 ) ( 9 a ^4 − 6 a ^2 g ^4 + 4 g ^8 )
Step-by-step explanation:
(3 a ² + 2 g⁴ ) ( 9 a⁴ − 6 a ² g⁴+ 4 g ⁸ ) is the factored form of the expression 27a⁶+ 8g¹²
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 27a⁶+ 8g¹²
In the expression the variables are a and g
The operators used in the expression are plus.
We need to find the factored form of the given expression.
When the quadratic expression is a product of two factors where each one is a linear expression, this is called the factored form
(3 a ² + 2 g⁴ ) ( 9 a⁴ − 6 a ² g⁴+ 4 g ⁸ )

The weights of 1000 onions from a certain farm follow a normal distribution with a mean of 150 g and a standard deviation 15 g from the data we can conclude that about blank onions way more than 165 g in about blank onions way less than 135 g
Answer:
About 159 weigh more than 165 g and about 159 g weigh less Than 135 g
Step-by-step explanation:
Given that :
Mean, μ = 150
Standard deviation, σ = 15
Using the Zscore formula :
Zscore = (x - μ) / σ
For x > 165
P(x > 165)
Z = (165 - 150) / 15
Z = 15 /15 = 1
P(Z > 1) = 0.15866 (Z probability calculator)
1000 * 0.15866 = 158.66 = 159
For x < 135
P(x < 135)
Z = (135 - 150) / 15
Z = - 15 /15 = - 1
P(Z > - 1) = 0.15866 (Z probability calculator)
1000 * 0.15866 = 158.66 = 159
