Answer:

x=110

Step-by-step explanation:

Use the polygon formula (n-2) × 180 where n is the number of points

The polygon has 7 points

(7-2) * 180 = 5 * 180 = 900

All the angles should add up to 900

119+86+167+283+64+71+x=900

x=110

Y=-x^2-10x+24 What is the y value of the vertex?

emmasim [6.3K]

Answer:

Step-by-step explanation:

1.) Get the equation in the form y = ax^2 + bx + c.

2.) Calculate -b / 2a. This is the x-coordinate of the vertex.

3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

1.) y = -x^2 - 10x + 24

2.) -(-10) / 2(-1) = -5

3.) y = -(-5)^2 - 10(-5) + 24

y = -25 + 50 + 24

y = 49

Answer:

19.5

Step-by-step explanation:

Given that;

Recipe calls for 5.25 grams of chocolate

Question Ask;

If you have 102.375 grams of chocolate, how many batches,of the recipe can you make?

Note;

102.375 ÷ 5.25 = b

102.375 ÷ 5.25 = Solution

Solve;

15 POINTS!!!!!!! PLEASE HELP!! Find the value of a. A) 3 B) 4 C) 6 D) 9

abruzzese [7]

Answer:

Step-by-step explanation:

The legs and hypotnuse of a triangle can easily be solved by using

$A^{2} +B^{2} =C^{2}$

with this in mind we can plug in the legs and hypotenuse of the triangle to solve for the missing leg, A.

$A^{2} =C^{2} -B^{2} \\A = \sqrt{(5^{2} )-(4^{2}) } \\A=\sqrt{9} \\A=3$

Hope this helps,

H.M.

Which algebraic expression is a polynomial with a degree of 3?

KatRina [158]

It would be the second choice. This expression is a polynomial because it is multiple terms and is a degree of three because the largest exponent is three. So your answer is:
2y^3 + 5y^2 - 5y
