Given the function G(r)=8r +4 what does G(8)=?

2 answers:

8 0

Hi there!

• Gᵣ = 8r + $4$

• Then,
for finding th' value of G(8) Substitute " 8 " in place of " r "

G₈ = 8 × 8 + 4

Multiply first, Accr'ding to B.O.D.M.A.S.

G₈ = 64 + 4

G₈ = 68

Hence, G₈ = 68

~ Hope it helps!

Hi there! The answer is 68.

If we want to find G(8), we must plug in r = 8 into the equation.

$g(8) = 8 \times 8 + 4$
Multiply first

$g(8) = 64 + 4$
Now add

$g(8) = 68$
Hence, the answer is G(8) = 68.

~ Hope this helps you!

256 to the nearest 1,000

gavmur [86]

Answer:

0 or 256.000.

Step-by-step explanation:

Why 0? If you round 256 to the nearest 1,000, it will give you 0 because as the rounding rule says is the digit is greater than 500 it rounds to up, but if the digit is less than 500 it rounds to down. But as 256 is less than a thousand and less than 500 it equals 0. If you put this title: rounding calculator, you can prove that my answer is correct.

Why 256.000? If you round 256 to the nearest thousands (3 decimals), it will give you 256.000. My explanation: because when rounding numbers that are less than needed it adds the decimal place from left to right. ( the answer is correct but the explanation may not be ).

Hope this helps.

Squaring the product of z and 5 gives the same

n200080 [17]

All the possible values of z can be found using (D) (5z)² = (5 + z)².

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

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
A mathematical statement made up of two expressions joined by an equal sign is known as an equation.
3x - 5 = 16 is an example of an equation.
We get the value of the variable x as x = 7 after solving this equation.

To find the following equations could be used to find all possible values of z:

The product of z and 5 = 5z
Sum of z and 5 = (5 + z)
Squaring the product of z and 5 gives the same result as squaring the sum of z and 5.
We can express the above statement as:
Squaring 5z gives squaring (5 + z)
So, (5z)² = (5 + z)²

Therefore, all the possible values of z can be found using (D) (5z)² = (5 + z)².

Juan wants to know the cross-sectional area of a circular pipe. He measures the diameter which he finds, to the nearest millimet

Tpy6a [65]

This question is not correctly written.

Correct Question

Juan wants to know the cross- sectional area of a circular pipe. He measures the diameter which he finds, to the nearest millimeter, to be 5 centimeters. To find the area of the circle, Juan uses the formula A=〖πr〗^2 where A is the area of the circle and r is its radius. He uses 3.14 for π.

a) What value does Juan get for the area of the circle? Make sure you include your units.

b) Michelle found the area of a circle as 78.5 〖in〗^2. She used 3.14 for π. What is the radius of the circle?

Answer:

a)The Area of the circle is 1962.5 millimeters ²

b) The radius of the circle is

5inches( in)

Step-by-step explanation:

a) The formula for the Area of a circle = πr²

The diameter of the circle was measured by Juan to the nearest millimeters = 5 centimeters

The first step is to convert 5cm to millimeters

1 centimetre = 10 millimeters

5 centimetres =

Cross multiply

= 5 × 10 millimeters

Therefore, 5 centimetres = 50 millimeters.

Since the Diameter of the circle = 50 millimeters,

Radius is calculated as Diameter ÷ 2

Therefore , the radius of the circle = 50 millimeters ÷ 2

= 25 millimeters.

The second step is to find the Area of the circle.

Area of the circle = πr²

Juan used 3.14 for π

Therefore , Area of the circle is calculated as:

= 3.14 ×(25millimeters)²

= 3.14 × 625 millimeters²

= 1962.5 millimeter ²

The Area of the circle is 1962.5 millimeters²

b) Michelle found the area of a circle as 78.5 〖in〗^2. She used 3.14 for π. What is the radius of the circle?

The formula to calculate the Area of a Circle is given as:

A( Area of a circle) = πr²

Since we are asked to find the radius of the circle in Part B, we can derive the formula to find the radius of a circle

A = πr²

r² = A ÷ π

r = √A÷ π

Therefore , the formula to find the Radius of a circle is given as :

r = √A ÷ π

Already given in the question are the following values :

Area of the circle = 78.5inches²

π = Michelle used 3.14

The radius of the circle

= r = √A ÷ π

r = √78.5 in² ÷ 3.14

r = √ 25

r = 5inches( in)

Therefore the radius of the circle is

5inches(in).
