An x-intercept is what x is equal to when y, or in this case q(x) is equal to 0. Lets set our equation up.
0=-2(x+3)^2 +8
-8=-2(x+3)^2
4=(x+3)^2
+-2=x+3
x=3+-2
x=1,x=5

Answer:
<u>$27,039</u>
Step-by-step explanation:
Calculating the amount of interest :
- A = interest
- P = principal
- r = rate of interest (in decimal)
- n = number of times compounded
- t = time (in years)
Given values :
- P = $17,000
- r = 4.75% = 0.0475
- n = 1
- t = 10
Solving :
- A = (17,000)(1 + 0.0475/1)¹⁰
- A = (17,000)(1.0475)¹⁰
- A = (17,000)(1.59052433)
- A = <u>$27,039</u> (nearest dollar)
Answer:
it is an increase because it is going up
Step-by-step explanation:
it is a 122.222% increase
A. side AB = 38/3 units B.m∠VYX =77°
Step-by-step explanation:
A.A rhombus has its four sides equal. This means side AB=side CD
Given that AB=5x+1 and CD=2x+8 equate the two sides to find value of x as;
5x+1=2x+8
collect like terms
5x-2x=8-1
3x=7
x=7/3
side AB = 5x+1
AB= 5*7/3 +1
AB=35/3 +1
AB=35/3 +3/3 = 38/3
B.
The diagonals of a rhombus intersect to form 90°
Hence
(3n²-0.75)°=90°
3n²=90°+ 0.75°
3n² =90.75° -----dividing by 3 both sides
n² =90.75°/3 =30.25°
n²=30.25°
n=√30.25°
n=5.5°
so angle Z =90°
and angle ZVW =(9n+2)°
∠ZVW = (9*5.5 +2 )° =51.5°
In a rhombus all four sides are equal, thus side VY = YX.This means triangle VYX is an isosceles triangle.
Hence angle ∠YVZ=∠WVZ =51.5°, and because VYX is an isosceles triangle then ∠YXV =51.5° so
∠VYX= 180°-(51.5°+51.5°)
=180°-103°=77°
