F(x) = 3x²-6x+2
f(2) = ?
f(2) = 3.2²-6.2+2
f(2) = 3.4-12+2
f(2) = 12-12+2
f(2) = 2
A) 2✔
Answer:
23.5
Step-by-step explanation:
First the shaded area is 28 but there is a triangle so we have to solve the area of the triangle. (formula for triangle: B x H x 1/2) 3 times 3=9 divided by 2=4.5
28-4.5=23.5
The speed of the plane will be equal to 240 Mph.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that:-
- Mattie Evans drove 350 miles in the same amount of time that it took a turbo propeller plane to travel 1200 miles.
- The speed of the plane was 170 mph faster than the speed of the car.
The speed of the plane will be calculated as:-
Let the speed of the car will be x mph so the speed of the plane will be
(x + 170)
Now time for the plane:-
Tp = Dp / Sp
Tp = 1200 / (x+170)
Now time for the car:-
Tc = Dc / Sc
Tc = 350 / x
It is given that time taken by both the plane and the car are equal:-
Tp = Tc
1200 / x+170 = 350 / x
1200x = 350x + 59500
850x = 59500
x = 59500 / 850
x = 70mph
The speed of the plane will be calculated By:-
Sp = x + 170 = 70 + 170 = 240 Mph
Therefore the speed of the plane will be equal to 240 Mph.

Answer:
h = 125
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
h = 63 + 62 = 125
Answer:
The slope of the line is 2
Step-by-step explanation:
In this problem you need to know rise over run. This means the slope goes up two and the over one. This makes the slope 2.
