Answer:
the angle is = 50
Step-by-step explanation:
8x+2+70+60=180° (interior angles of a triangle add up to 180°)
8x+132=180
8x=180-132
8x=48
divide with the coefficient of x both sides
x=6
substitute
(8(6)+2)+70+60=180
50+70+60=180
180=180

[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:

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? *
Answers
Answer:
First Problem: 200 ft/hour Second Problem: 3 ft/hour
Step-by-step explanation:
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
Problem 2:
R = D/T
90/30=3

(-3) to the sixth power in exponential form
Answers
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.
