2x^2+15x=8
factor or solve as indicated, show all work.
please and thank u!
Answers
Answer: x= -8 or x = 1/2
Step-by-step explanation:
2x^2 + 15x = 8 Subtract 8 from both sides to let the whole equation equal 0
- 8 -8
2x^2 + 15x - 8 = 0 Now find two numbers that if you multiply them, their product will be -16 and their sum will be 15. An example is the numbers 16 and -1. 16 times -1 is -16 and 16 plus -1 is 15.
Rewrite the whole equation in this form,
2x^2 +16x - 1x - 8 = 0 Factor on the left side
2x ( x + 8) -1 (x + 8) = 0 Now factor out x + 8
(x + 8) (2x -1) = 0 Set each expression equal zero, because for the whole expression to equation to 0, either one of them or all of them have to equation zero.
x + 8 = 0 or 2x - 1 = 0
-8 -8 +1 +1
x = - 8 2x = 1
x = 1/2

. Write the exponential function modeling an initial population of 67,000 and a relative growth rate of 1.7% per year. What population does your function project at the end of 37 years?
Answers
Answer:
In 37 years the population will be 125,012
Step-by-step explanation:
Giving the following information:
Initial population (PV)= 67,000
Growth rate (g)= 1.7%= 0.017
Number of years (n)= 37
First, we will establish the future value (FV) formula:
FV= PV*(1+i)^n
FV= 67,000*(1.017^n)
Now, for 37 years:
FV= 67,000*(1.017^37)
FV= 125,012
In 37 years the population will be 125,012
What is true regarding two adjacent arcs created by two intersecting diameters? They always have equal measures. The difference of their measures is 90°. The sum of their measures is 180°. Their measures cannot be equal.
Answers
Answer:
The sum of their measures is 180°
Step-by-step explanation:
In the case when the similar circles are intersected to each other having two diameters so the following conditions would be considered as true
1. The arcs that are opposite would be equal
2. The sum of adjacent arcs would be 180 degrees
3 And, the sum of all arcs would be 360 degrees
So according to the given situation, the third option is correct
And, the rest of the options are incorrect

solve the following equation 5a-4>2a+8
Answers
Answer:
4
Step-by-step explanation:
Simplifying
5a + -4 = 2a + 8
Reorder the terms:
-4 + 5a = 2a + 8
Reorder the terms:
-4 + 5a = 8 + 2a
Solving
-4 + 5a = 8 + 2a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
-4 + 5a + -2a = 8 + 2a + -2a
Combine like terms: 5a + -2a = 3a
-4 + 3a = 8 + 2a + -2a
Combine like terms: 2a + -2a = 0
-4 + 3a = 8 + 0
-4 + 3a = 8
Add '4' to each side of the equation.
-4 + 4 + 3a = 8 + 4
Combine like terms: -4 + 4 = 0
0 + 3a = 8 + 4
3a = 8 + 4
Combine like terms: 8 + 4 = 12
3a = 12
Divide each side by '3'.
a = 4
Simplifying
a = 4

If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________
Answers
Answer:
x = ∞ infinite solutions or 0
HI = infinite solutions
ID = infinite solutions.
Step-by-step explanation:
Oh okay I got this now!
ID + HI = DH
ID + 2x - 4 = 4x + 10 (subtract 2x on both sides)
ID - 4 = 2x + 10 (add 4 on both sides)
ID = 2x + 14
So now ID + HI = DH
2x + 14 + 2x - 4 = 4x + 10 (simplify)
4x + 10 = 4x + 10 (subtract 10 on both sides)
4x = 4x (minus 4x on both sides)
0 = 0
I would plug in 0 as x.

What is Scale Drawing?A scale drawing is a drawing made by enlarging or reducing the size of the original object.
The factor by which the drawing is enlarged or reduced is called the scale factor.
Given that,
Scale of a drawing is,
1 inch = 1/8 inch
That is, a drawing is drawn for which it is drawn 1/8 inch for actual dimension of 1 inch.
So, drawing is reduces by 1/8
So scale factor = 1/8
Hence the scale factor of the drawing is 1/8.

Given :
A farmer has 300 feet of fence available to enclose a 4500 square foot region in the shape of adjoining squares, with sides of length x and y.
The big square has sides of length x and the small square has sides of length y.
To Find :
The value of x and y.
Solution :
From attached figure perimeter is given by :
x + x + x + y + y + y + ( x-y ) = 300 ft
4x + 2y = 300
2x + y = 150 ...1)
Now, area is given by :
A = x² + y²
x² + y² = 4500 ...2)
Putting value of y in equation 2), we get :
[tex]x^2 + ( 150 - 2x)^2 =4500\\\\x^2 + 4x^2 + 22500-600x =4500\\\\5x^2 -600x + 18000=0\\\\x^2 - 120x +3600=0\\\\x^2-2\times x\times 60 + 60^2 =0\\\\(x-60)^2 =0\\\\x = 60\ ft[/tex]
y = 150 - ( 2× 60 )
y = 30 ft
Therefore, the value of x and y is 60 ft and 30 ft respectively.
