Answer:
5 is co efficient
8x is term
9 is constant
Step-by-step explanation:
Answer:
B) F
You put √22 in a calculator and it gives you ≈ 4.69
You don't give much information but I will give you the definition of "density".
In all simpleness, the definition of density is the compactness of a substance.
Density can be found with the formula; p = m/v
p = density
m = mass
v = volume
Best of Luck!
Answer:
AE = 7.5
Step-by-step explanation:
Since <BAC =
, then;
<BAD = <DAE = <CAE =
(complementary angles)
From ΔABC, applying the Pythagoras theorem to determine the length of side AC;
=
+ ![/AB/^{2}](https://tex.z-dn.net/?f=%2FAB%2F%5E%7B2%7D)
=
+ ![/5/^{2}](https://tex.z-dn.net/?f=%2F5%2F%5E%7B2%7D)
100 =
+ 25
= 100 - 25
= 75
AC = ![\sqrt{75}](https://tex.z-dn.net/?f=%5Csqrt%7B75%7D)
Applying trigonometric function to ΔCAE,
Cos
= ![\frac{AE}{\sqrt{75} }](https://tex.z-dn.net/?f=%5Cfrac%7BAE%7D%7B%5Csqrt%7B75%7D%20%7D)
AE =
× Cos ![30^{0}](https://tex.z-dn.net/?f=30%5E%7B0%7D)
= 7.5
Therefore, AE = 7.5
Step-by-step explanation:
y is directly proportional to x^2.
This means that y = kx^2, where k is a real constant.
When x = 7, y = 245:
245 = k(7)^2 = 49k. By division, k = 5.
Now we know that y = 5x^2, when x = 9, y = 5(9)^2 = 5 * 81 = 405.
