Answer:

Prove that KL is equal to c by Pythagorean Theorem.


Step-by-step explanation:

In the two triangles triangle KLM is a right triangle with sides a and b as the two legs of the right triangle .We can apply Pythagorean Theorem to find KL.

In triangle KGF two sides are a and b .If we prove KL=EF then Pythagorean Theorem will be true for triangle KGF and hence we can prove triangle KGF to be a right triangle.

The correct option to prove triangle KGF to be a right triangle is to Prove that KL is equal to c by Pythagorean Theorem.

<span>Which of the following can be used to prove that triangle EFG is also a right triangle?

Prove that the sum of a and c is greater than b.
Prove that the sum of a and b is greater than c.
Prove that the ratio of EF and KL is greater than 1 and hence, the triangles are similar by AA postulate.
Prove that KL is equal to c by Pythagorean Theorem.

The correct answer is:
</span>Prove that KL is equal to c by Pythagorean Theorem.

It can also be "Prove that triangles are congruent by SSS property and hence angle EGF is equal to angle KML"

Answer:

y=3r+5

Step-by-step explanation:

Break up the sentance.

Capon city has 5 more than 3 times as many residents as harbor city.

The sentance above can be written like this: y=5+3x. Since they want r to represent the number of people in Harbor city, use r in place of x.

Capon city=y

has=equal sign

5 more=+5

3 times as many=3r

y=3r+5

The value of a house has increased by $4,200 in the past year. By what percent has the value increased if the value last year wa
IgorC [24]

Answer:

The value has increased by <u>8 percent</u>.

Step-by-step explanation:

Given:

The value of a house has increased by $4,200 in the past year.

The value last year was $52,500.

Now, to find the percent increased.

<em>Value of house = $52,500.</em>

<em>Value of house last year increased by = $4200.</em>

So, to get the percent increased:

\frac{Value\ of\ house\ last\ year\ increased\ by} {Value\ of\ house}\times 100.

=\frac{4200}{52500} \times 100

=0.08\times 100

=8\ percent.

Therefore, the value has increased by 8 percent.

The function f(x) = 7(1.32)x models the number, in billions, of the DNA sequences in a database x years since 2010. What does th
NikAS [45]

Answer:

The correct option is (A).

Step-by-step explanation:

The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:

f(x)=7\cdot (1.32) x

The general growth function can be represented as:

y=a\cdot (1+r)^{t}

Here,

<em>y</em> = final value

<em>a</em> = initial value

<em>r</em> = growth rate

<em>t</em> = time

Com-paring the two functions we get:

1+r=1.32\\r=1.32-1\\r=0.32

This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.

Thus, the correct option is (A).
