Answer:
a=-1
Step-by-step explanation:
we need to get a by itself
first combine like terms
12+16a=-4
now we need to get rid of the 12 so subtract it to other side
-16=16a
now divide 16 by -16 which gives you -1=a
h(t) = at^2 + vt +h0
What is the sum of the measures of the interior angles of an octagon? Enter your answer in the box.
The sum of interior angles of an octagon will be 1080°.
We have a Octagon.
We have to find the sum of the measures of the interior angles of a pentagon.
What is Octagon ?In geometry, a Octagon is a eight - sided polygon.
According to the question, we have - A Octagon.
The formula for finding sum of the measures of the interior angles of a polygon is = ( n - 2) x 180°. The number of triangles in each polygon is two less than the number of sides.
The formula for calculating the sum of interior angles is:
For a Octagon - n = 8.
Therefore - the sum of interior angles of an octagon will be -
(8 - 2) x 180
180 x 6
1080°
Hence, the sum of interior angles of an octagon will be 1080°.

solve for y. 3[y-13]=12
Answer:
y = 17
Step-by-step explanation:
3(y-13)=13
3y-39=12
3y=51
y=17
Answer:
y = 17
Step-by-step explanation:
3[y-13] = 12
3*y + 3*-13 = 12
3y - 39 = 12
3y = 12 + 39
3y = 51
y = 51/3
y = 17
Check:
3[17-13] = 12
3*4 = 12

A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds after it was hit can be modeled by the function h(t)=40t-16t^2.
Move the number to the blanks to describe the path of the ball.
When the ball is hit at 0 seconds, it has a height of _____ feet. The ball's height increases until it reaches its maximum height of _____ feet after ____ seconds. The ball's height then decreases until it reaches the ground _____ seconds after it was hit.
Fill in the blanks with these numbers: 0, 0.4, 1.25, 2, 2.5, 4, 16, 25, 40
Answer:
The correct numbers are;
1) 0
2) 25
3) 1.25
4) 2.5
When the ball is hit at 0 seconds, it has a height of 0 feet. The ball's height increases until it reaches its maximum height of 25 feet after 1.25 seconds. The ball's height then decreases until it reaches the ground 2.5 seconds after it was hit
Step-by-step explanation:
The given equation for the height of the ball, h(t), in feet, is given as follows
h(t) = 40·t - 16·t²
Therefore;
1) When the ball is hit at 0 seconds, it has a height of h(0) = 40×0 - 16×0² = 0 feet
2) The time to reach maximum height by the ball is found by taking the derivative (slope) of the function for the height of the ball and noting that at maximum height, the derivative (slope) = 0
Therefore;
h'(t) = 40 - 2 × 16·t = 0
40 - 32·t = 0
t = 40/32 = 5/4 seconds = 1.25 seconds
3) The maximum height is then found from the value of the function at t = 5/4 seconds as follows;
h(5/4) = 40×5/4 - 16×(5/4)² = 50 - 25 = 25 feet
4) The time in which the ball reaches the ground where h(t) = 0 is given from the formula for the height of the gulf ball as follows;
h(t) = 0 = 40·t - 16·t²
40·t - 16·t² = 0
(40 - 16·t)·t = 0
Therefore;
t = 0 seconds or t = 40/16 = 2.5 seconds
(40 - 16·t) = 0/t = 0
t = 40/16 = 2.5 seconds
Therefore, the filling the blanks with the correct numbers gives;
When the ball is hit at 0 seconds, it has a height of 0 feet. The ball's height increases until it reaches its maximum height of 25 feet after 1.25 seconds. The ball's height then decreases until it reaches the ground 2.5 seconds after it was hit
hello I have a question to ask.
A man's age today is three years less than four times the age of his oldest daughter. Let a represent the daughter's age. Write an expression to represent the man's age.
Solve for f.
Round your answer to 2 decimals.
9f = {(12f – 2)
Answer:
f=0.67
Step-by-step explanation:
Let's solve your equation step-by-step by isolating f.
9f=12f−2
Step 1: Subtract 12f from both sides.
9f−12f=12f−2−12f
You get:
−3f=−2
Step 2: Divide both sides by -3.
−3f/−3 = −2/−3
You get:
f= 2/3, or f= 0.67

20 lbs of bananas cost $100. How many lbs of bananas can you get with $85 ?
Answer:
$17
Step-by-step explanation:
Step 1:
20 : 100 = x : 85
Step 2:
100x = 1700
Answer:
x = 17
Hope This Helps :)
Answer:
$100= 20lbs
$1= (20/100)lbs
$85= 85*(20/100)lbs
= 85(1/5)lbs
= 17 lbs

I need help with B.
Answer:
6x= 42
x= 7
Step-by-step explanation:
a) Area= length ×width
2100= 50 ×width
width= 2100 ÷50
width= 42 ft
Thus, the field is 42ft wide.
b) width of field
= x +3x +2x
= 6x
Since we know that the field is 42ft wide from (a),
Equation: 6x= 42
x= 42 ÷6
x= 7
I need help it’s geometry it’s due today at 11:59 pm Texas time
Answer:
to be parallel
slope should be equal
for first question
y=1/3X +2
comparing with y=m1x+c
slope = 1/3
similarly for second equation
y=1/3x -4
comparing with y=m2x + c
m2= 1/3
since m1=m2
lines are parallel

la edad de josé y beatriz están en la relacion de 5 a4 . si dentro de 3 años la suma de ambas edades seran 60 años , ¿ cual es la edad de beatriz ?
Answer:
La edad actual de Beatriz es de:
30 años
Step-by-step explanation:
Planteamiento:
5e = 4b
(e+3) + (b+3) = 60
e = edad actual de José
b = edad actual de Beatriz
Desarrollo:
de la segunda ecuación del planteamiento:
e + b + 6 = 60
e + b = 60 - 6
e + b = 54
e = 54 - b
sustituyendo este último valor en la primer ecuación del planteamiento:
5(54-b) = 4b
5*54 + 5*-b = 4b
270 - 5b = 4b
270 = 4b + 5b
270 = 9b
b = 270/9
b = 30
e = 54 - b
e = 54 - 30
e = 24
Comprobación:
5e = 4b
5*24 = 4*30 = 120
Pls help Im very stuck on this and don’t understand
Answer:
C. 85 degrees
Step-by-step explanation:
Step 1: Set up equation
x + 57 + 96 + x = 131
Step 2: Solve for x
2x + 153 = 131
2x = -22
x = -11
Step 3: Find m∠RQU
m∠RQU = 96 + x
m∠RQU = 96 - 11
m∠RQU = 85°
In the adjoining figure, GP bisects angle BGH and HP bisects angle GHD. calculate the size of angle a.
Answer:
90°
Step-by-step explanation:
AB and CD are parallel lines and EF is reversal
Therefore angles BGH and DHG are consecutive interior angles
As we know the sum of consecutive interior angles equals to 180°:
∠BGH + ∠DHG = 180°Line GP bisects angle BGH , therefore
m∠PGH = 1/2*m∠BGHLine HP bisects angle GHD, therefore
m∠PHG = 1/2*m∠GHDSum of two angles of triangle GHP:
m∠PGH + m∠GHD = 1/2(∠BGH + ∠DHG) = 1/2*180° = 90°Therefore the missing angle a is:
∠a = 180° - (m∠PGH + m∠GHD) = 180° - 90° = 90°- 32x - 40
