(x - h)^2 = 4p(y - k)
(-1 - 3)^2 = 4p(8 - 0.5)
(-4)^2 = 4p(7.5)
16 = 30p
p = 16/30
p = 8/15
(x - 3)^2 = 16/15(y - 0.5)
15(x^2 - 6x + 9) = 16y - 8
15x^2 - 90x + 135 = 16y - 8
16y = 15x^2 - 90x + 135 + 8
y = 15/16 x^2 - 90/16 x + 143/16
f(x) = 15/16 x^2 - 90/16x + 143/16
<span>3 1/8 x 3 3/5
= 25/8 x 18/5
= 5/4 x 9
= 45/4</span>
angle 4 is the same as angle 8
angle 7 & angle 8 has to equal 180 degree
so angle 7 and angle 4 also have to equal 180
angle 4 is 3 times the size of 7
lets call 7 (x)
so 4(x) = 180
180/4 =45
x=45
angle 7 is 45 degrees
Answer: $506.25
Step-by-step explanation:
1. Find 40% of $843.75
- The decimal value of 40% is 0.4. We can multiply 0.4 by 843.75 to find the discount on the computer.
-> 0.4*843.75= 337.5
2. Now that we have the discount, we can subtract 40% of the original price to find the new price.
843.75 - 337.5 = $506.25
