Answer:
first one is 82% second is 214%
Step-by-step explanation:
Step 1: Divide 288 by 351 to get the number as a decimal. 288 / 351 = 0.82
Step 2: Multiply 0.82 by 100. 0.82 times 100 = 82
Step 1: Divide 212 by 99 to get the number as a decimal. 212 / 99 = 2.14
Step 2: Multiply 2.14 by 100. 2.14 times 100 = 214
Answer:
144 degrees
Step-by-step explanation:
We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:
(n-2)(180) = ?
(10-2)(180) = ?
(8)(180) = 1440.
Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).
1,440/10 = 144
= <u>144 degrees</u>
1+tan^2(A) = sec^2(A) [Pythagorean Identities]
tan^2(A)cot(A) = tan(A)[tan(A)cot(A)] = tan(A)[1] = tan(A)

Answer:
3x^2 -4
Step-by-step explanation:
F(x)=2x^2+3 and g(x)=x^2-7
(f+g)(x) =
We add the two functions together
(f+g)(x) =2x^2+3+x^2-7
I like to line them up vertically
(f+g)(x) =
2x^2 +3
+x^2 -7
