Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees

If f(x) is differentiable for the closed interval [-4, 0] such that f(-4) = 5 and f(0) = 9, then there exists a value c, -4 <

WITCHER [35]

Mean value theorem

For $f:[a,b] \rightarrow \mathbb{R}$ exist $c \in (a,b)$ such that

$f'(c)=\dfrac{f(b)-f(a)}{b-a}$

$f'(c)=\dfrac{f(-4)-f(0)}{-4-0}=\dfrac{5-9}{-4}=\dfrac{-4}{-4}=\boxed{1}$

Solve y/10 ≤ 9 A) y ≥ 90 B) y ≤ 80 C) y ≤ 90 D) y ≥ 900

Studentka2010 [4]

Answer:

C. y ≤ 90

Step-by-step explanation:

Since ≤ means lesser than or equal to, we need to find a y value that is lesser than or equal to 90, which is 10 * 9.
