Answer:

4.5 cm

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r where r is the radius

28.3 = 2 * (3.14) *r

28.3 = 6.28 r

Divide each side by 6.28

28.3/6.28 = r

4.506369427=r

The approximate length of the radius is 4.5 cm

Step-by-step explanation:

Total marbles = 12 + 30 + 20 + 10 + 8 = 80

Answer:

4.4 ft

Step-by-step explanation:

The sides of a right triangle are "tied together" mathematically by an equation called the Pythagorean theorem, which says: in any right triangle, the relationship between the two sides that make the right angle (we'll call them a and b) and the side across from it (c) is

[tex]a^2+b^2=c^2[/tex]

Let's sustitute these for the values we have in our problem (measured in feet)

[tex]9^2+a^2=10^2\\81+a^2=100\\a^2=19\\a=\sqrt{19}[/tex]

19 is between the perfect squares [tex]4^2=16[/tex] and [tex]5^2=25[/tex], so [tex]\sqrt{19}[/tex] must be between 4 and 5, a little bit closer to 4. Punching the expression into the calculator confirms this with a value of [tex]\sqrt{19}\approx4.3588[/tex] which we can round to 4.4 ft.

Answer:

X = Y - 11873.21

X = 17009.1 feet

Step-by-step explanation:

Let x represent the elevation of Mt. Wilson. And

Y = Mt snow Crest.

Since Snow Crest is 11,873.21 feet higher than Mt. Wilson, the equation will be

X = Y - 11873.21

Where Y = 28,882.31

Substitute Y into the equation

X = 28882.31 - 11873.21

X = 17009.1 feet.

The interval over which the function f(x) is negative is (-infinity, -4) .

Given,

The values of f(x) for corresponding x .

Here,

From the table,

x = -8 ; f(x) = -16

x = -6 ; f(x) = -8

Thus from the data given in the table it is clear that the function f(x) will be negative if we decrease the value of x .

Thus f(x) will be negative for the values which are smaller than -8 .

Now,

When

x = -4 ; f(x) = 0

x = -2 ; f(x) = 8

Thus f(x) changes its sign at x = -4.

So,

Interval in which f(x)  will be negative : (-infinity, -4) .

Answer:

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

The formula of the quadratic function is [tex]y = -8x^2 + 6[/tex]

A quadratic function is represented as:

[tex]y = a(x - h)^2 + k[/tex]

The vertex of the quadratic function is given as:

[tex](h,k) = (0,6)[/tex]

So, we have:

[tex]y = a(x - 0)^2 + 6[/tex]

This gives:

[tex]y = ax^2 + 6[/tex]

The quadratic function passes through (-1,-2).

So, we have:

[tex]-2 = a(-1)^2 + 6[/tex]

[tex]-2 = a + 6[/tex]

Subtract 6 from both sides

[tex]a = -8[/tex]

Substitute -8 for a in [tex]y = ax^2 + 6[/tex]

[tex]y = -8x^2 + 6[/tex]

Hence, the formula of the quadratic function is [tex]y = -8x^2 + 6[/tex]

Answer:

The value of the digit 3, written as a fraction is[tex]\frac{3}{100}[/tex]

Step-by-step explanation:

Number : 9.13

A place value tells you the location of each digit in a number.

If a number has a decimal point,

The first digit to the right of the decimal point is the number of tenths.

The second digit to the right of the decimal point is the number of hundredths.

The first digit to the left of the decimal point is the number of ones.

The second digit to the right of the decimal point is the number of tens.

So, The digit three is The second digit to the right of the decimal point is the number of hundredths.

So, the value of the digit 3, written as a fraction is[tex]\frac{3}{100}[/tex]

Hey there! I'm happy to help you! :)

We see that there are 160 songs in total. Let's split them up into groups of rock, country, and pop.

ROCK

Our problem says that 3/8 of the songs are rock songs. We know that we have 160 songs. We just need to multiply 3/8 by 160 and we will have the number of rock songs.

3/8*160=60

Therefore, we have 60 rock songs.

COUNTRY

We see that 25% of our songs are country songs. 25% is the same thing as 1/4, or 0.25. We can multiply this by our total number of songs to see how many are country.

0.25(160)= 40

We have 40 country songs.

POP

All we have in the problem is that the remaining songs are pop. The nice thing is is that we already know how many rock and country songs we have, so we can simply subtract those from 160 and we will then be able to tell how many pop songs there are.

160-60-40= 60

Therefore, there are 60 pop songs.

I hope that this helps you! Have a wonderful day!
