Answer:

<CFD =62°

<AFB= 90°

Step-by-step explanation:

here you have a vertical angle, so to simply put it the answer on one side of the angle is the same answer for the opposite side of the angle. knowing this, angle <AFE is 62° and <CFD is on the opposite side making the angle the same(62°). the opposite angle of <AFB is <EFD which is 118° but both <AFB and <AFC equal 118° so you subtract 118° to <AFC degree which is 28° and you get 90°.

i hope this makes sense im not good at explaining. if anyone has a better explanation feel free to correct me.

sesenic [268]
 <span>The two dice rolls are independent, so the fact that you roll an even number on the 2nd dice has no bearing on the probability that the first die shows a 1, 2, 3, or 6. Answer: 4/6 = 2/3.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

3. A rocket is launched vertically from the ground with an initial velocity of 64 ft / sec . ( a ) Write a quadratic function h
lys-0071 [83]

Answer:

See below.

Step-by-step explanation:

The rocket's  flight is controlled by its initial velocity and the acceleration due to gravity.

The equation of motion is h(t) = ut + 1.2 g t^2 where  u = initial velocity, g = acceleration due to gravity ( = - 32 ft s^-2) and t = the time.

(a) h(t) = 64t  - 1/2*32 t^2

h(t) = 64t - 16t^2.

(b) The graph will be a parabola which opens downwards  with a maximum at the point (2, 64) and x-intercepts at (0, 0) and (4, 0).

The y-axis is the height of the rocket and the x-axis  gives the time.

Maximum height = 64 feet, Time to maximum height = 2 seconds, and time in the air = 4 seconds.

Split the second term in 3a^2 - 8a + 4 into two terms

3a^2 - 2a - 6a + 4 = 0

Factor out common terms in the first two terms, then in the last two terms.

a(3a - 2) -2(3a - 2) = 0

Factor out the common term 3a - 2

(3a - 2)(a - 2) = 0

Solve for a;

a = 2/3,2

<u>Answer : B. (2/3,2)</u>

Isabella constructed a cylindrical vase that has a volume of 63 cubic centimeters.Jasonbconstructed a cone that had the same hei
Korvikt [17]
<span>cylindrical vase
r=radius </span>cylinder=radius cone
h= height cylinder=height cone
Volume  cylindrical vase (V1)= 63 cm³=pi*r² *h

cone
Volume cone (V2)=pi*r² *h
if radius cylinder=radius cone  and height cylinder=height cone
then V1=V2
therefore
V2= 63 cm³

the answer is The volume of cone is 63 cm³
