Stella [2.4K]

Answer:

The diameter is 47

Step-by-step explanation:

Given

C = 147.58--- Circumference

\pi = 3.14

Required

Determine the diameter (d)

The circumference of a circle is:

C = \pi d

Make d the subject

d = \frac{C}{\pi}

d = \frac{147.58}{3.14}

d = 47

IM SOO CONFUSEDD help???
lozanna [386]

Answer:

D.

Step-by-step explanation:

To tell whether the domains can include 0, all you need to do is find where x = 0, and whether the y-value is real.

h(x) = sqrt(2x^2 + 5x - 3)

= sqrt(0^2 + 5 * 0 - 3)

= sqrt(-3)

Since this includes the square root of a negative number, h(0) is an imaginary number. That means that we can eliminate choices A and B.

If you look at the graph of w(x), when x = 0, there is a real value for the y-value on the graph. But, if you think about it, if you have 0 workers, there is no way that you can still be producing wrenches. So, the domain cannot contain 0.

Your answer will be D.

Hope this helps!!

A positive real number is 5 more than another. When - 10 times the smaller is added to the square of the larger, the result is 5
salantis [7]

Answer:

4√2 and 5+4√2

Step-by-step explanation:

Let the two numbers be x ad y

Smaller = y

Bigger = x

If a positive real number is 5 more than another, then;

x = 5 + y ... 1

When - 10 times the smaller is added to the square of the larger, the result is 57, then;

-10y + x² = 57 ...2

Substitute 1 into 2;

-10y + (5+y)² = 57

-10y + 25+10y+y² = 57  

y²+25 = 57

y² = 57 - 25

y² = 32

y = √32

y = 4√2

Since x = 5 + y

x = 5 + 4√2

Hence rhe numbers are 4√2 and 5+4√2

Combine like terms.<br><br> y + 3 + 9(y + 5) =
Mnenie [13.5K]

Answer:

The answer is 10y + 48.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

y + 3 + 9(y + 5) \\  = y + 3 + 9y + 45

Next you have to collect like-terms :

y + 3 + 9y + 45 \\  = 10y + 48
