Evaluate the polynomial function when H=3
f(h)=4h^3-3h^2+5h-16
Answer:
80
Step-by-step explanation:
f(3)=4(3)^3-3(3)^2+5(3)-16
f(3)=4(3*3*3)-3(3*3)+15-16
f(3)=4(27)-3(9)+15-16
f(3)=108-27+15-16
f(3)=81+15-16
f(3)=96-16
f(3)=80

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft

the answer is 48 your welcome
(2^2)^4 = 256
3^4 = 81
256 × 81 = 20735
27 × 16 = 432
20735÷432 = 47.99
round to 47.99 to the nearest 10th and you will get 48.

14.4 = -2.4b
Answer:
b = -6
Step-by-step explanation:
14.4 = -2.4b (swap the sides of the equation)
-2.4b = 14.4 (divide both sides of the equation by -2.4)
b = -6
What is the product of 7.1 * 10^3 and 5.8 * 10^2 expressed in scientific notation?
Answer:
4.118 * 10^6
Step-by-step explanation:
When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.
41.18*10^5 = 4,118*10^6
(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)
Answer:
411.8 · [tex]10^{4}[/tex]
Step-by-step explanation:
7.1 · 10³ × 5.8 · 10²
7.1 × 5.8 = 41.18
10³ + 10² = [tex]10^{5}[/tex]
41.18 · [tex]10^{5}[/tex]
Scientific notation can only have one digit after the decimal.
411.8 · [tex]10^{4}[/tex]

Solve the quadratic equation by completing the square. 0 = x2 – 6x + 4 –4 = x2 – 6x –4 + 9 = (x2 – 6x + 9) 5 = (x – 3)2
Answer:
x = 3±√5
Step-by-step explanation:
Given the quadratic equation;
0 = x² – 6x + 4
Swap sides
x² – 6x + 4= 0
Subtract 4 from both sides
x² – 6x + 4 - 4= 0 - 4
x² – 6x = -4
Complete the square;
Add the square of half of coefficient of x to both sides
Coefficient of x = -6
Half of Coefficient of x = -6/2 = -3
square of the half of Coefficient of x = (-3)²
Add (-3)² to both sides
x² – 6x + (-3)² = -4 + (-3)²
(x-3)² = -4 + 9
(x-3)² = 5
Take the square root of both sides
x - 3 = ±√5
x = 3±√5
This gives the solution to the equation

A.only 2 sides are the same length
B.only 2 angels have the same measure
C. Each side is a different length
D. All sides are the same length
E. Each angel has a different measure
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

One number is 8 more than another, and their sum is 80. What is the smaller number?
34
36
38
40
========================================================
Work Shown:
x = smaller number
x+8 = larger number, since it's 8 more than the smaller value
Add up those two expressions, and set the sum equal to 80.
Then solve for x.
x+(x+8) = 80
2x+8 = 80
2x = 80-8 ... subtract 8 from both sides
2x = 72
x = 72/2 .... divide both sides by 2
x = 36
The smaller value is 36 while the larger value is x+8 = 36+8 = 44
Note how 36+44 = 80 to help verify the answer.
Answer:
34.
Step-by-step explanation:
80 = (34 + 8) + x
80 = 42 + x
38 = x
^^ that is an answer, but the question asks for the SMALLER number... Which is up at the beginning of my equation.
I hope this helps. I'm not entirely sure if it's correct, but it's worth a shot... lol

What is the solution to the following equation?
7x−5=2x+5
Answer:
x = 2
Step-by-step explanation:
7x−5=2x+5
step 1 add 5 to each side
-5 + 5 = cancels out
5 + 5 = 10
we now have 7x = 2x + 10
step 2 subtract 2x from each side
2x - 2x cancels out
7x - 2x = 5x
we now have 10 = 5x
step 3 divide each side by 5
5x / 5 = x
10 / 5 = 2
we' re left with x = 2

Is a triangle with side lengths of 10, 11, 14 a right triangle?
Answer:
no
Step-by-step explanation:
A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle

Yes

Find the distance between the pair of points.
(2, -2), (-5, -2
Answer:
7
Step-by-step explanation:
Answer:
7 units
Step-by-step explanation:
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Plug in what you know.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(49) + (0) }[/tex]
Add.
[tex]d = \sqrt{(49)[/tex]
Evaluate the radical.
d = ±7
Since distance cannot be negative, our answer is 7.
The distance between the two points is 7 units.
Hope this helps!
