Answer:

The answer is B or 1/5/

Step-by-step explanation:

We know that it hold the letters A,B,C,D, and E. That makes it have 5 different letters in it. There is only one of each letter in the box too. This makes it have a 1/5 of a chance of picking the letter E.

Answer:

reflection

Step-by-step explanation:

Answer:

Reflection

Step-by-step explanation:

As you can see, its the same shape, and the same size...but it looked mirrored. ABC has been reflected over the y-axis to make DEF.

It's not rotation, because the shape has not been rotated, if so it would have been in a different position

It's not translation, because the shape didn't stay in the same format (facing one side).

So it must be reflection

Answer:

No solution

Step-by-step explanation:

Please write this as 3 sqrt x + 8 = -4.  

Note that if we try to isolate 3 sqrt x by subtracting 8 from both sides, we get 3 sqrt x = -12.  There is no real solution; sqrt x can never be negative.

Answer:

[tex]m = -\frac{23}{42}[/tex]

Step-by-step explanation:

here is the equation for slope (m):

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

where:

y₂ = y-coordinate of 2nd point = -10

y₁ = y-coordinate of 1st point = 36

x₂ = x-coordinate of 2nd point = 93

x₁ =  x-coordinate of 1st point = 9

plug values into equation:

[tex]m =\frac{-10-36}{93-9} \\\\m = \frac{-46}{84} \\[/tex]

reduce the fraction:

[tex]m = -\frac{23}{42}[/tex]

Answer:

Step-by-step explanation:

Answer:

m= -5/9

Step-by-step explanation:

m= y2-y1/ x2-x1

m= -3-2/ 5-(-4)

m= -3-2/ 5+4

m= -5/9

y= mx + b

(-4,2)

2= -5/9(-4) + b

2= 2.2+ b

-2.2 +2= b

-0.2= b

Answer:

Width=75

length=105

Step-by-step explanation:

Width=x

length=30+x

= 7875=x*30+x

x^2+30x-7875=0

x^2+105x-75x-7875=0

x(x+105)-75(x+105)=0

Answer:

The answer is 2

Step-by-step explanation:

Since the number 1 plus 1 is 2

Answer:

C: 55

Step-by-step explanation:

Rearrange the bracketed terms to:

(10 + 0) + (10 + 1) + (10 + 2) + ... + (10 + 10)

There are 11 brackets so we have (11 * 10) + (0 + 1 + 2 + ... + 10) =

(11 * 10) + 55

Answer:

E = 108

Step-by-step explanation:

E = 3 * [tex]6^{2}[/tex]

Answer:

Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = 2√(x-8)

y² = 4(x-8) = 4x-32

4x = y²+32

x = 0.25y² +8

★ Volume of cylinder :-

Here,

We have :

Substituting the values :

> V = π (2 × 2) × 7

> V = 4π × 7

> V = 28π

★ Volume of cone :-

We have :

Substituting the values :

> V = ⅓ × π × (2 × 2) × 6

> V = ⅓ × π × 4 × 6

> V = ⅓ × π × 24

> V = 8π

★ According to the question :-

Adding them together,

> Total Volume = 8π + 28π

> Total Volume = 36π

[tex]Total \: \: \: Volume = (88+176) {cm}^{2} \\ \\ = 264 {cm}^{2} .[/tex]

Answer:

n = 8

Step-by-step explanation:

1/2(n + 4) = 6

1/2 of n + 2 = 6

6 - 2 = 4

4 × 2 = 8

1/2 of 8 + 2 = 6

4 + 2 = 6

n = 8

Answer:

x= 7

Step-by-step explanation:

5x-11=24

  +11   +11

5x   =  35       35/5 = 7        x=7

5(7) - 11 = 24

35 - 11 = 24

Answer:

x=7

Step-by-step explanation:

5x7= 35

35-11=24

5x7-11=24

Answer:

Equation for M → g(x) = [tex]\frac{5}{4}x^{2} + 2[/tex]

Equation for N → h(x) = [tex]\frac{5}{4}(x+4)^2-1[/tex]

Step-by-step explanation:

Vertex of the graph of y = f(x) is (2, -1)

Therefore, equation of the function will be,

y = a(x - 2)² - 1

Since this graph passes through a point (0, 4),

4 = a(0 - 2)² - 1

4 = 4a - 1

a = [tex]\frac{5}{4}[/tex]

Hence, we get the equation of the function 'f' as,

f(x) = [tex]\frac{5}{4}x^{2} -1[/tex]

Now this graph has been shifted 3 unit up to get the new graph M

Equation for M will be,

g(x) = f(x) + 3

g(x) = [tex]\frac{5}{4}x^{2} - 1 + 3[/tex]

g(x) = [tex]\frac{5}{4}x^{2} + 2[/tex]

Further graph of function 'f' is shifted 4 units to the left then equation of the new function (N) will be,

h(x) = f(x + 4)

h(x) = [tex]\frac{5}{4}(x+4)^2-1[/tex]
