Volume of cone= 1/3πr^2h

8842.24 m^3= 1/3πr^2h

1/3*3.14*33*r^2= 8842.24m^3

r^2 = 8842.24*3/3.14*33

r^2= 26526.72/103.62

r^2 = 256

r= √256

All real numbers (In interval form (-∞,∞) )

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). This set is the values that the function shoots out after we plug an x value in.

here, we have,

Given,

From the graph,

To find the domain of the function.

Now,

We know that a domain of a function is the set of the all the x-values for which the function is defined.

By looking at the graph of the function we see that it is a graph of a upward open parabola and the graph is extending to infinity on both the side of the x-axis this means that the function is defined all over the x-axis i.e. for all the real values.

Also, we know that the function will be a quadratic polynomial since the equation of a parabola is a quadratic equation and as we know polynomial is well defined for all the real value of x.

The domain of the function is:

Hence,  All real numbers (In interval form (-∞,∞) )

Answer:

f(-2) = - 4

Step-by-step explanation:

f(x) = x² + 3x - 2

f(-2) = ( -2)² + 3 *(-2) - 2

= 4 - 6 - 2

= 4- 8

= - 4

Step-by-step explanation:

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

[tex] =\tt 2500 - 2245[/tex]

[tex] =\tt 255[/tex]

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]

[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]

[tex] =\tt 255 = \frac{2500x}{100} [/tex]

[tex] = \tt255 \times 100 = 2500x[/tex]

[tex] = \tt25500 = 2500x[/tex]

[tex] =\tt \frac{25000}{2500} = x[/tex]

[tex]\color{plum} =\tt \bold{10.2\%}[/tex]

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

Answer:

[tex]EG \perp FH[/tex]

[tex]m\angle EFH = 45^\circ[/tex]

Step-by-step explanation:

Given

See attachment for square EFGH

Required

Select the true statements

The sides of the square are EF, FG, GH and HE while the diagonals are: EG and FH

The diagonals of a square meet at [tex]90^\circ[/tex] . This implies that: EG and FH are perpendicular i.e. [tex]EG \perp FH[/tex]

Also, the diagonals divide the angles at the edges ([tex]90^\circ[/tex]) into two equal angles ([tex]45^\circ[/tex])

This means that:

[tex]m\angle EFH = 45^\circ[/tex]

The other two options are false.

i.e.

[tex]EP \ne EH[/tex]

[tex]FP \ne 2(EG)[/tex]

Answer:

Step-by-step explanation:

Answer:

Yes; there is only one range value for each domain value.

Step-by-step explanation:

For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

Answer:

3y+9

Step-by-step explanation:

Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.

So G) is a function, bc for every x there is just 1 y

H) is not a function

I) is not a function either

Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)

1. function

2. not a function

3. function

4. function

5. not a function

6. not a function

i might be wrong, but i hope this helps!

Answer:

G-Function, H-Not a function, I-Not a Function

Step-by-step explanation:

G is the only one that doesn't repeat its x values

Answer:

[tex]2\frac{1}{4}[/tex]

Step-by-step explanation:

20 1/4 = 20.25

20.25/9 = 2.25

2.25 = [tex]2\frac{1}{4}[/tex]

Each cake weighs 2.25 pounds.

The weight of each cake will be equal to 2(¹/₄).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

A mixed expression, also known as a complex fraction, is a fraction that contains a fraction in the numerator, the denominator, or both the numerator and the denominator.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Nine identical cakes weigh a total of 20¼ pounds.

20(¹/₄) = 20.25

20.25/9 = 2.25

2.25 = 2(¹/₄).

Answer:

Gross = $712.5

Social security = $44.175

Medicare = $10.33125

Step-by-step explanation:

Given that :

Hourly pay = $15

Hours over 40 = 1.5 * $15 = $22.5

Total hours worked last week = 45

Total pay :

(40 * $15) + (45 - 5)*$22.5

$600 + $112.5

= $712.5

Hence, weekly gross pay = $712.5

Social security tax percent =(6.2%)

0.062 * gross = 0.062 * $712.5 = $44.175

Medicare tax percent = (1.45%)

0.0145 * $712.5 = $10.33125

Answer:

NM > LN

Step-by-step explanation:

Here, we want to write an inequality

we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively

as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;

So we can conclude that;

NM > LN

50y + 75x ≥ 1000 ;

50(15) ≥ 750;

x ≥ 4

y ≥ 15

Step-by-step explanation:

Given that :

Number of stickers sold = y

Cost of sticker = 50

Cost of bag tag = 75

Number of bag tags sold = x

Total worth of items sold ≥ 1000

1)

50y + 75x ≥ 1000

2.)

To make atleast 15 stickers

y ≥ 15

Atleast 15 stickers :

50(15) ≥ 750

3.)

A possible solution :

50(15) + 75(x) ≥ 1000

Answer: 3mph

Step-by-step explanation:

Speed is calculated as Distance/Time.

Igor's distance = Speed × Time

= 6 × 2

= 12m

Since they ran same distance, Sally also ran 12m

Sally's speed = Distance/Time

where,

Distance = 12m

Time = 4 hours

Average speed = 12/4 = 3mph
