Answer: 15.58 miles

Step-by-step explanation:

Given two sides and an included angle, segment AB can be calculated using the cosine rule :

Given a = 15.6 miles, b = 12.3 miles and C=α=66.7°

To find c:

c= √(a^2+b^2-2abcosα

c = √ 15.6^2 + 12.3^2 -(2 × 15.6 × 12.3)cos66.7°

c = √243.36 + 151.29 - 151.79454

c = √242.85545

c = 15.583820

c = 15.58 miles

Find the vertex of the parabola y = 8x2.

murzikaleks [220]

Answer:

vertex is at (0,0)

Step-by-step explanation:

Find the vertex of the parabola y = 8x2.

I assume you meant y = 8* x^2

this can be compared to the general vertex form y = a (x - h)^2 + k

where vertex at (h, k)

so then...

h =0 and k = 0 here

vertex is at (0,0)

I need help on this question so if u actually can answer it correctly and show how you got it that would be helpful thx

$\rm \looparrowright - \frac{1}{4} (8 - 4 + 20x)$

Subtract the numbers

$\rm \looparrowright - \frac{1}{4} (4+ 20x)$

Factor out 4 from the expression

$\rm \looparrowright - \frac{1}{ \cancel4} \times \cancel4(1 + 5x)$

$\rm \looparrowright - (1 + 5x)$

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

$\rm \looparrowright - 1 - 5x$

<em>Thus, Options A and F are correct!!~</em>

Answer:

The measure of angle < AED is $100\°$

Step-by-step explanation:

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite.

$m$

substitute the values and solve for x

$4x=\frac{1}{2}(120\°+2x)$

$8x=(120\°+2x)$

$8x-2x=120\°$

$6x=120\°$

$x=20\°$

$m$

$m$ -----> by supplementary angles

substitute value

$80\°+m$

$m$

Ratling [72]

Answer:

from the given info

you can know that there were 16 red ones. (2/3)*24

and 8 green apples

and her classmates ate 3/4 of red ones i.e.

(3/4)*16

=12

and 1/2od green

i.e.

(1/2)*8

and now the total eaten apples

= 12+4

=16

and the remaining number are

24-16
