Answer:p=12
Step-by-step explanation:
(9p)+(p+21)+(p+27)=180
9*12=108
12+21=33
12+27=39
108+33+39=180
so p=12

Choose the polynomial that is written in standard form.
−3x5 + 4x3 + 10x2
−8x + 4x4 + 3x3
x4 + 4x3 + 10x4
x6 + 4x3 + 10x7
Answer:
A. −3x⁵ + 4x³ + 10x²Step-by-step explanation:
The standard form means that the terms are ordered from biggest exponent to lowest exponent.Verify the answer options
A. −3x⁵ + 4x³ + 10x²
5, 3, 2 - correct orderB. −8x + 4x⁴ + 3x³
1, 4, 3 - incorrect orderC. x⁴ + 4x³ + 10x⁴
4, 3, 4 - incorrect orderD. x⁶ + 4x³ + 10x⁷
6, 3, 7 - incorrect orderAnswer:
[tex] { - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]
Step-by-step explanation:
For a polynomial to be in standard form, it must satify the conditions below:
1) It must not contain like terms
2) The exponents (powers) must be written in descending order
That is, the polynomial must be of the form
[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]
Where a, b, c, m, n, are coefficients/constants
The only option that satifies the above conditions, and follows the pattern f(x) shown is:
[tex]{ - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

(-3) to the sixth power in exponential form
Answer:
Step-by-step explanation:
A negative number raised to an even exponent gives a positive result so it is the same as 3 raised to 6. That is 3 x 3 x 3 x 3 x 3 x 3 = 729
The (-3) to the sixth power, (-3)⁶, is equal to 729.
To express (-3) to the sixth power in exponential form, we write it as (-3)⁶.
Now, let's calculate (-3)⁶ properly:
(-3)⁶ = (-3) * (-3) * (-3) * (-3) * (-3) * (-3)
Multiplying -3 by itself six times:
(-3) * (-3) * (-3) * (-3) * (-3) * (-3) = 729
Therefore, (-3) to the sixth power, (-3)⁶, is equal to 729.
By raising -3 to the power of 6, we obtain the result of 729.

I NEED HELP WITH THIS one angle of a triangle measured 145 degrees. The other two angles are in a ratio of 2:3. what are the measures of those two angles?
Answer:
Step-by-step explanation:
A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:
[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]
Now that we know what x is, we can multiply that to our ratio:
[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

Find the surface area
please show work
363 inch²
Step-by-step explanation:
Each vertical face is a rectangle.
Area of each face = length x breadth
= 8 x 6 inch² = 48 inch²
There are 5 such faces, total area = 5 tiimes of 48 inch² = 240 inch²
For horizontal faces:
Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). With base 6 inch & height 4.1 inch.
For 2 such faces, you have 2 x 5 times of area of 1 ∆.
Area of 10∆s = 10 ( ½ x 4.1 x 6) = 123 inch²
Total area = area of horizontal surfaces + area of vertical surfaces
Total area = 240 + 123 inch² = 363 inch²

A climber is on a hike. After 4 hours he is at an altitude of 800 feet. After 12
hours, he is at an altitude of 1400 feet. What is the average rate of change? *
Answer:
First Problem: 200 ft/hour Second Problem: 3 ft/hour

R = D/T
So, 800/4=200
We will check if the rate matches for the second example rate:
1400/12=200. It does, so we know we are correct
