When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be
c^2 = a^2 + b^2
If a = 21 and c=29, thus
b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units.
Thus, the answer is <span>D) B = 400</span>
Answer: 4.35 - 5.5 = -1.15 ≈ - (23÷20)
Step-by-step explanation:
4.35 - 5.5= -1.15
The equivalent equation to 4.35 - 5.5 will be,
-1.15 ≈ - (23÷20)
<span>Answer: A) exponential, because there is a relatively consistent multiplicative rate of change

temperature thrice. If you compare time=0 until time=30, you will get this table
t(10)- t(0)= 180-200= -20
t(20)-t(10)= 163-180= -17
t(30)-t(20)= 146-163= -17
</span>t(40)-t(30)= 131- 146= -15
t(50)-t(40)= 118-131= -13
t(50)-t(40)= 107-118= -11
There is something weird about the 2nd and 3rd value because it was same -17., but there seems to be a +2 change to the difference. So, the graph would be exponential with a <span>relatively consistent multiplicative rate of change</span>
Answer:
13.05MbpS < x < 22.15 Mbps
Step-by-step explanation:
Confidence interval CI can be expressed in the form;
Lower bound < x < upper bound
Given;
CI = (13.046, 22.15)
Lower bound = 13.046 = 13.05 Mbps (to two s.f.)
Upper bound = 22.15 Mbps
So, the Confidence interval is given as;
13.05 MbpS < x < 22.15 Mbps
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2
