Answer:

x = 3

Explanation:

The one way you can figure this out is by using Pythagorean Theorem (a^2 + b^2 = c^2). If you did that, you’d get:

4^2 + b^2 = 5^2

If you solved this problem, you’d get b = 3.

If g(x)=2x+3 is a function,then find the unknown term in the following ordered pairs.
Dmitrij [34]

Answer:

a=2, b = 1, m=9

Step-by-step explanation:

i. 7 = 2a+3 -----> 4=2a---------> a=2

ii. -1 = 2b-3 -------> 2 = 2b ------> b = 1

iii. 2(3)+3 = m -------> 6+3 = m -------> m=9

Hope this helps!!! :D

2. A right triangle has a hypotenuse of 15 cm. What are possible lengths for the two legs of the triangle? Explain your reasonin
dolphi86 [110]

Answer:

Two possible lengths for the legs A and B are:

B = 1cm

A = 14.97cm

Or:

B = 9cm

A = 12cm

Step-by-step explanation:

For a triangle rectangle, Pythagorean's theorem says that the sum of the squares of the cathetus is equal to the hypotenuse squared.

Then if the two legs of the triangle are A and B, and the hypotenuse is H, we have:

A^2 + B^2 = H^2

If we know that H = 15cm, then:

A^2 + B^2 = (15cm)^2

Now, let's isolate one of the legs:

A = √( (15cm)^2 - B^2)

Now we can just input different values of B there, and then solve the value for the other leg.

Then if we have:

B = 1cm

A = √( (15cm)^2 - (1cm)^2) = 14.97

Then we could have:

B = 1cm

A = 14.97cm

Now let's try with another value of B:

if B = 9cm, then:

A = √( (15cm)^2 - (9cm)^2) = 12 cm

Then we could have:

B = 9cm

A = 12cm

So we just found two possible lengths for the two legs of the triangle.

Find the area of a circle with radius, r = 60cm. Give your answer rounded to 3 SF.
katrin [286]

The area of the circle will be equal to 11309.733 square centimetres.

<h3>What is an area?</h3>

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

The area of the circle will be calculated by the following formula:-

Area = πr²

Area = π x ( 60 x 60 )

Area = 3.14 x 60 x 60

Area = 11309.733 square centimeters.

Therefore the area of the circle will be equal to 11309.733 square centimetres.
