Find the perimeter and area of isosceles trapezoid EFGH. A=1/2(b1+b2)•h

Mathematics
1 answer:
vfiekz [6]3 years ago
7 0

We have a height of 4, bottom base of 8, top base of 6, so

A = (1/2)(8+6)(4) = 28

Perimeter, we have sides that are hypotenuses of a right triangle, legs 1 and 4,

s = √(1²+4²) = √17

So perimeter is

P = 8 + 6 + √17 + √17 = 14+ 2√17

Answer: Area 28, perimeter  14 + 2√17

Find the geometric means in the following sequence.
soldi70 [24.7K]

Answer:

Last choice. d.

Step-by-step explanation:

We are given the first term and the sixth term.

The first term is a_1=-9.

The sixth them is a_6=a_1r^5=-9216.

Let's solve for the common ratio, r.

-9r^5=-9216

Divide both sides by -9:

r^5=1024

Take the fifth root of both sides:

r=1024^{\frac{1}{5}}

r=4

So the common ratio is 4.

a_1=-9

a_2=-9(4)=-36

a_3=-9(4)^2=-144

a_4=-9(4)^3=-576

a_5=-9(4)^4=-2304

a_6=-9(4)^5=-9216

Find the length of the second leg of the triangle round to the nearest hundredth
horsena [70]

Answer:

\displaystyle \frac{3\sqrt{230}}{5}

Step-by-step explanation:

Use the Pythagorean Theorem:

\displaystyle a^2 + b^2 = c^2 \\ \\ 9,7^2 + b^2 = 13,3^2; \sqrt{82,8} = \sqrt{b^2} \\ \\ \frac{3\sqrt{230}}{5}\:[or\:9,0994505329...] = b

So, you have this:

\displaystyle 9,1 ≈ b

Which exponential equation is equivalent to the logarithmic equation below?
julsineya [31]

Answer:

\implies\boxed{ 10^a = 300 }

Step-by-step explanation:

We are provided logarithmic equation , which is ,

\implies log_{10}^{300}= a

  • Here we took the base as 10 , since nothing is mentioned about that in Question .

Say if we have a expoteintial equation ,

\implies a^m = n

<u>In</u><u> </u><u>logari</u><u>thmic</u><u> </u><u>form</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>,</u><u> </u>

\implies log_a^n = m

Similarly our required answer will be ,

\implies\boxed{ 10^a = 300 }
