7. Factor. (x - 2)(4x + 5) = 0 The zeroes are 2 and -5/4. The answer is C.
8. Vertex form is: f (x) = a(x - h)^2<span> + k and (h, k) is the vertex.
So plug in. f(x)=a(x+1)^2-10
Plug in x and y to find k.
2 = a(1+1)^2-10
2=a(2)^2-10
2=4a-10
4a=12
a=3
f(x)=3(x+1)^2-10
H is the answer.</span>
Answer:
172 ft 2
Step-by-step explanation:
SA=2lw+2lh+2hw, for
A=2(lw + lh + hw)=2·(7 · 2+ 8 · 2 + 8 · 7)= 172 ft 2.
Hope this helps,
Best of Luck!
Answer:
Step-by-step explanation:
Hello There!
We can solve for x using trigonometry
More specifically the law of sines
In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)
so to find x we use this equation
step 1 multiply each side by sin 59
now we have
so we can conclude that x = 14.6
<u>Answer-</u>
<u>Solution-</u>
Alisa saved $3,600 and then she is taking $300 each month from this saving account.
Taking number of months on abscissa and amount of money in account on ordinate.
In the beginning, i.e when number of month is 0, the amount of money in her savings account will be = $3600. This is why 3600 is the y-intercept of the the equation.
Then, she withdraws money from the account at a rate of $300 per month, so the slope of the equation will be -300 (-ve sign is because the amount is decreasing)
The Slope-Intercept formula of straight line is,
Where,
m = slope, c = y-intercept
Putting the values,
