Answer:

exact: V = 45pi in.^3

approximate: V = 141.4 in.^3

Step-by-step explanation:

V = (pi)r^2h

r = d/2 = 6 in./2 = 3 in.

V = (pi) * (3 in.)^2 * 5 in.

V = 45pi in.^3

V = 141.4 in.^3

Answer:

Assume that the two digits are x and y (x is at ones position and y is at tens position)

if we subtract the digit of a two digit number, we get 4.

this means,

x-y=4    ..................... (1)

if we interchange the digits of the number and subtract the new number from the original number we get 44.

this means,

old no. 10y+x

new no. 10x+y

10y+x-(10x+y)=44

10y+x-10x-y=44

9y-9x=44    ........................... (2)

solve the two equations:

id these two equations are solved, we get no solution.

meaning, such a number with these given conditions do not exist

From what I have learnt:

The number has an ending so it is rational

Irrational numbers don't end, e.g. π (3.1415926...)

Answer:

Step-by-step explanation:

The graph of a function should pass the vertical line test in order to be a function.

Option A

Option B

Option C

Option D

The rule is .

Every domain of the function should have an unique range i.e f(x)=y

#1

f(14) has two values hence not a function

#2

f(15) has two values hence not a function

#3

f(16) has two values hence not a function

#4

Yes it's a function,every domain has an unique range

Answer:

A= 306,87°

B= 196,26°

C= 112,62

Step-by-step explanation:

sinA =-4/5

A = -53,24°

A = 306,87°

tan B = 7/24

B = 16,26°

B = 196,26°

cos C = -5/13

C = 112,62°

Answer:

[tex] \frac{4}{?100} \times \frac{2000}{1?} = 80 \\ \\ 2000 + 80 = 2080 \\ \\ \\ 2080 \times 12 = 24960[/tex]

Answer:

Solid A

Step-by-step explanation:

3 feet is 3 x 12 = 36 inches, which is less than 48 inches, so solid A has a larger surface area than solid B.

Answer:

54 degrees.

Step-by-step explanation:

So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).

Given this, set these values equal to each other to get the value of a.

d = a + b

2a = (a+10)+44

2a = a + 54

a = 54

The measure of the exterior angle is 54 degrees.

Answer:

Umm i would go with A

*If im wrong im sorry*

Answer:

Option A: {-2, 3, 1, 5}

Step-by-step explanation:

A function is a relationship that maps elements from one set (the domain, set of the inputs, the independent variables) into elements from another set (the range, set of the outputs, the dependent variables ).

Such that the standard notation is (x, y)

This says that the function/relation maps the element x into the element y.

So here the independent variable is x.

Now, in a relation:

{ (x₁, y₁), (x₂, y₂), ..., (xₙ, yₙ)}

The independent variable is represented with the set:

{x₁, x₂, ..., xₙ}

then, in the relation:

(–2, 4), (3, –2), (1, 0), (5, 5)

The set that represents the independent variable is a set with the first elements from each one of these four points:

{-2, 3, 1, 5}

The correct option is A.

Answer: The Answers are A, and C.

Answer:

The answer is C and D

Step-by-step explanation:

If you find the percentage of 95% of 6 it will give you an answer of 5.7

.95 x.006 equals 0.0057

95x6 equals 570

0.95 x 6 equals 5.7

95/100 x 6 equals 5.7

Given:

The graph of an inequality.

To find:

The inequality in slope intercept form.

Solution:

The slope intercept form is:

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-0=\dfrac{-3-0}{0-(-3)}(x-(-3))[/tex]

[tex]y=\dfrac{-3}{3}(x+3)[/tex]

[tex]y=-1(x+3)[/tex]

[tex]y=-x-3[/tex]

From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".

[tex]y\geq -x-3[/tex]

Therefore, the required inequality is [tex]y\geq -x-3[/tex].

Identify

f(x) = 35x + 25

g(x) = 22x + 18

f(4) is x = 4 for function f(x)

g(10) is x = 10 for function g(x)

Step 2: Find Function Values

f(4)

Step-by-step explanation:

Answer:

11:

since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111
