Answer:
D 92.
Step-by-step explanation:
if a || b and e || f
THEN...
x + 1 = y

z = x - 3
x = 91
y = 92
z = 88
answer is 92
f(x) = x4 - 9x3 - 8x2 - 9x - 2; f(-3)
-
Answer:
Step-by-step explanation:
f(x) = x⁴ - 9x³ - 8x² - 9x - 2
f(-3) = (-3)⁴ -9*(-3)³ - 8*(-3)² - 9*(-3) - 2
= 81 - 9*(-27) - 8*9 + 27 -2
= 81 + 243 - 72 + 27 - 2
= 277
Answer:

What is the value of m in this proportion?
1/2/3/5=13m
(they are all one big fraction)
Enter your answer as a fraction in simplest form in the box.
The value of m in the proportion is 5/78.
What is proportion?
The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.
To solve for m in the proportion:
1/2/3/5 = 13m
We can simplify the left-hand side of the equation by multiplying the first fraction by the reciprocal of the second fraction, and multiplying the third fraction by the reciprocal of the fourth fraction. This gives:
(1/2) ÷ (3/5) = 13m
(1/2) × (5/3) = 13m (using the rule a/b ÷ c/d = a/b × d/c)
5/6 = 13m
To isolate m, we can divide both sides of the equation by 13:
5/6 ÷ 13 = m
m = 5/78
Therefore, the value of m in the proportion is 5/78.

The altitude to the hypotenuse of a right triangle bisects the hypotenuse. How does the length of the altitude compare with the length of the segments of the hypotenuse. Explain completely. Use Geogebra to help you set up a diagram and show evidence that supports your conclusion.
*Search up Geogebra and take a pic of your triangle*
And explain and show evidence that supports your conclusion.
Any questions please feel free, I will answer your questions.
[tex] \frac{1}{2}[/tex]will be the answer.
Step-by-step explanation:-
If the altitude to the hypotenuse of a right-angled triangle bisects the hypotenuse, then we can know that the triangle is Isosceles right triangle. (AB=AC)
Make AB=AC=2, so,
BC=[tex] \sqrt{ {2}^{2} + {2}^{2} } [/tex]= [tex] \sqrt{4 + 4} [/tex]= [tex] \sqrt{8} [/tex]
Prime factorizing, we get,
BC = [tex] \sqrt{2 \times 2 \times 2} [/tex]
Take two 2's outside by taking common because of "square" root,
⇢BC = [tex]2 \sqrt{2} [/tex]
BD = DC = [tex] \sqrt{2} [/tex],
AD = [tex] \sqrt{AB^{2} - BD^{2} } [/tex]= [tex] \sqrt{4 - 2} [/tex]= [tex] \sqrt{2} [/tex]
So, AD=BD=CD= [tex] \frac{1}{2}[/tex]BC

how do you create a line ?
you mark 2 points, take a ruler and draw a line through both points (and extend the line beyond the points as far as the chart goes).
how do you find points ?
you think about a nice value for x (really, any value on the x-axis of the chart is OK) and then calculate y.
you mark the point at this x, y coordinates.
you know, the x-axis is the horizontal coordinate line, and the y-axis is the vertical coordinate line.
so, I would pick x =0. that gives us y = 0 + 0.5 = 0.5.
and maybe x = 2. that gives us y = 2 + 0.5 = 2.5
so, you have (0, 0.5) and (2, 2.5) as points.
and then simply do as described above.

A building is constructed using bricks that can be modeled as right rectangular prisms with a dimension of 8\frac{1}{2}8 2 1 in by 3\frac{1}{4}3 4 1 in by 3\frac{1}{2}3 2 1 in. If the bricks weight 0. 04 ounces per cubic inch and cost cost $0. 08 per ounce, find the cost of 1700 bricks. Round your answer to the nearest cent
Rounded to the nearest cent, the cost of 1700 bricks would be $504.21.
To determine the cost of 1700 bricks, we need to calculate the total weight of the bricks and then multiply it by the cost per ounce.
Calculate the volume of one brick:
- Length = [tex]8\frac{1}{2}[/tex] inches
- Width = [tex]3\frac{1}{4}[/tex] inches
- Height = [tex]3\frac{1}{2}[/tex] inches
Volume = Length x Width x Height
Then Weight per cubic inch = 0.04 ounces
Weight = Volume x Weight per cubic inch
To Calculate the total weight of 1700 bricks:
Total weight = Weight per brick x Number of bricks
Cost per ounce = $0.08
Cost = Total weight x Cost per ounce
Volume = 8.5 inches x 3.25 inches x 3.5 inches
Weight per cubic inch = 0.04 ounces
Weight = Volume x Weight per cubic inch
The Total weight of 1700 bricks:
Total weight = Weight x 1700
Cost per ounce = $0.08
Cost = Total weight x Cost per ounce
1. Volume of one brick:
Volume = 8.5 inches x 3.25 inches x 3.5 inches = 92.6875 cubic inches
2. Weight of one brick:
Weight per cubic inch = 0.04 ounces
Weight = 92.6875 cubic inches x 0.04 ounces = 3.7075 ounces
3. Total weight of 1700 bricks:
Total weight = 3.7075 ounces x 1700 = 6302.575 ounces
4. Cost of the bricks:
Cost per ounce = $0.08
Cost = 6302.575 ounces x $0.08 = $504.21
Rounded to the nearest cent, the cost of 1700 bricks is $504.21.

Answer:
x^3 - 21x^2 + 144x - 324
Step-by-step explanation:
f(x) = x^2 - 15x + 54
g(x) = x - 6
To find f(x) x g(x), you just substitute the values of f(x) and multiply it with g(x).
(x^2-15x+54)(x-6) = x^3 - 15x^2 + 54x - 6x^2 + 90x - 324
