Answer:

Step-by-step explanation:

Area of a triangle = $\frac{bh}{2}$

where b = base length and h = height

the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5

So area =

$\frac{2\frac{1}{2} *4\frac{2}{5} }{2} \\\\2\frac{1}{2} *4\frac{2}{5} =11\\\\\frac{11}{2} =5.5$

5.5 also = $5\frac{1}{2}$

Hence, the correct answer is A

Answer:

Step-by-step explanation:

length of rectangle = circumference of circle = πd = 6π cm

area of rectangle = 2×6π = 12π cm

area of one circle = πr² = 9π cm²

surface area = 12π + 2(9π) = 30π ≅ 90 cm²

H(t)= (t+3)^2 + 5

Answer:

The average rate of change for the given function in the interval (-5, -1) is 0 (zero)

Step-by-step explanation:

The average rate of change of a function over an interval is the quotient between the difference between the function evaluated at the ends of the interval divided by the length of the interval. That is for our case:

the average rte of change of h(t) in the interval (-5, -1) is:

$\frac{h(-1)-h(-5)}{-1+5}$

so we find:

$h(-1)=(-1+3)^2+5=2^2+5=4+5=9\\and\\h(-5)=(-5+3)^2+5=(-2)^2+5=4+5=9$

then the average rate of change becomes:

$\frac{h(-1)-h(-5)}{-1+5}=\frac{9-9}{4} =\frac{0}{4} =0$

Ms cais class is studying a study pattern.the rule for the tile pattern is y=10x-18.kalil thinks that figure 12 of this pattern

Allisa [31]

I assume that x = figure no.

It's better to write this as

Tiles = 10n-18

Thus 10(12) - 18

=120 - 18

= 102

THUS HE IS WRONG.
