F(x) = -(x+7)² + 4
f(x) = -(x+7)(x+7) + 4
f(x) = -(x² + 7x + 7x + 49) + 4
f(x) = -x² - 14x - 49 + 4
f(x) = -x² - 14x - 45
True for f(x)
<span>the equation is quadratic.
the vertex is (7,4)
</span><span>the y-intercept is (0,4)</span>
The legnth is irrelivant
we know that
Circumference=2 times pi time radius
c=40
40=2 times pi times radius
divide both sides by 2
20=pi times radius
divide both sides b pi
20/pi=radius
the radius is 20/pi cm or aproximately 6.366199048 cm
Answer:
x=30
Step-by-step explanation:
2x+x+90=180 (anglesome prop.)
3x+90=180
3x=180-90=90
3x=90
x=90/3=30
Answer:
Mean = 4.4
Mode = 2
Range = 13
Explanation:
Given Data set = 1, 2, 2, 2, 3, 4, 5, 5, 6, 14
Mean = Add all the numbers together and divide is by the number of terms in the data set. = <u>44/10 = 4.4</u>
Mode = Most repeated number in the data set = <u>2</u>
Range = Largest Number - Smallest Number = <u>14 - 1 = 13</u>
Hope this helps!
