Answer:

A. 82°

B. 144°

C. 75°

D. 150°

E. 241°

F. 80°

Step-by-step explanation:

A circle is 360°

A. 360 - 278 = 82 °

B. 360 - (124 + 92) = 144 °

C. 360 - (255 + 30) = 75 °

D. 360 - (118 + 30 +62) = 150 °

E. 360 - (21 +41 + 57) = 241 °

F. 360 - (30 + 60 + 80 + 110) = 80°

Also, the 80° is congruent so it's the same on both sides.

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the
Monica [59]

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function , which is

h(t) =-t^2+\frac{4}{3}t+ \frac{1}{4}

When the grasshopper land on the ground,

h(t)=0

that is,

-t^2+\frac{4}{3}t+ \frac{1}{4}=0

Multiplying whole equation by 12 to get rid of denominators 3 and 4

-12t^2+16t +3=0

(3-2t)(6t+1)=0 \\ 3-2t=0 , 6t+1=0 \\ t= \frac{3}{2} , \frac{-1}{6}

And time cant be negative, so the correct option is

t = \frac{3}{2}=1.5 seconds

Correct option is C .

Write the standard form of the line that passes through (-1,-3) and (2,1)
Pie
Answer:

5 =  - 2x - y
To find this you must find the slope first:
\frac{y - y1}{x - x1}
which is, after performing some calculating is -2.

Next you need to set up your eqaution:
y - y1 = m(x - x1)
when you set it up, and substitute the variables for your slope and points you should get this:
y - ( - 3) =  - 2(x - 1)
y + 3 =  - 2x - 2
add 2 to both sides
y + 5 =  - 2x
subtract y from both sides
5 =  - 2x - y
