Answer:

D

Step-by-step explanation:

The slope m is a measure of the rate of change

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, - 1) ← 2 points on the line

m = [tex]\frac{-1+4}{1-0}[/tex] = [tex]\frac{3}{1}[/tex] = 3 → D

Answer:

2, 12, 36, 80

Step-by-step explanation:

Substitute n = 1, 2, 3, 4 into the n th term formula, that is

a₁ = 1³ + 1² = 1 + 1 = 2

a₂ = 2³ + 2² = 8 + 4 = 12

a₃ = 3³ + 3² = 27 + 9 = 36

a₄ = 4³ + 4² = 64 + 16 = 80

I hope this helps!

$55.25 is the cost of the coat after the sale.

Step-by-step explanation:

Given:

Price of the coat = $65

Percentage of discount = 15%

To find:

The cost price of coat after the sale

Solution:

Cost price of coat = $65

Percentage of discount = 15%

The amount of discount will be 15% of the price of the coat.

Amount of discount :

[tex]=\frac{15}{100}\times \$65 \\=\$9.75[/tex]

The cost price of the coat:

[tex]=\$65-\$9.75=\$ 55.25[/tex]

$55.25 is the cost of the coat after the sale.

Step-by-step explanation:

The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.

However, I'll solve for the vertex of the given function.

Given

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

Vertex, V is of the form:

[tex]V= (h,k)[/tex]

Where

[tex]h = -\frac{b}{2a}[/tex]

and

[tex]k = f(h)[/tex]

Solving for h:

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]y = ax^2 + bx + c[/tex]

So:

[tex]a = -9.5[/tex]

[tex]b = 47.5[/tex]

[tex]c = 63[/tex]

[tex]h = -\frac{b}{2a}[/tex]

[tex]h = -\frac{47.5}{2 * -9.5}[/tex]

[tex]h = -\frac{47.5}{-19}[/tex]

[tex]h = \frac{47.5}{19}[/tex]

[tex]h = 2.5[/tex]

Solving for k

[tex]k = f(h)[/tex]

[tex]k = f(2.5)[/tex]

Substitute 2.5 for x in [tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]k = -9.5 * 2.5^2 + 47.5* 2.5 + 63[/tex]

[tex]k = -59.375+ 118.75 + 63[/tex]

[tex]k = 122.375[/tex]

Hence:

The vertex is

[tex]V = (2.5,122.375)[/tex]

Answer:

if ur doing savvas

Step-by-step explanation:

answer for the first one is:
Micah used the wrong sign for b in the formula x=-b/2a

answer for the second one is:
vertex is = (-2.5, 122.375)

Answer:

-24

Step-by-step explanation:

You start with -6 points, and get another -6 on the rest of the turns which is a total of 4 turns.

-6 x 4 is -24

Unless this question is missing some information, this should be correct I believe.

Hope this helps!

The score after 4 turns is -24.

Given that, you play a game where you score -6 points on the first turn and on each of the next 3 turns.

We need to find what is the score after 4 turns.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.

Now, the score after 4 turns = Score of the first turn + The next 3 turns

= -6 + 3(-6)

=-6-18

=-24

Therefore, the score after 4 turns is -24.

Step-by-step explanation:

Answer:

The final value of the stock is $3,996.66

Step-by-step explanation:

Percentage Change

The x% of a number N is calculated as x*N/100. If there is an increase, that number is added to the original value, then the new value is:

N'=N+x*N/100

Operating:

N'=N(1+x/100)

That formula makes it easier to find the new values of increasing quantities. When the percentage is for decreasing, then the formula becomes:

N'=N(1-x/100)

The original value of the stock is N1=3,789. The first change is an increase of 6%, then the new value is:

N2=3,789(1+6/100)=3,789*1.06=$4,016.34

The stock value now decreases by 7%:

N3=4,016.34(1-7/100)=4,016.34*0.93=$3,735.20

Finally, the value increases again by 7%:

N4=3,735.20(1+7/100)=3,735.20*1.07=$3,996.66

The final value of the stock is $3,996.66

Answer:

common ration = 1/4

12th term = 1/65536

Step-by-step explanation:

64

64*1/4 = 16

16 * 1/4 = 4

4* 1/4 = 1

1 * 1/4 = 1/4

1/4*1/4 = 1/16

1/16*1/4 = 1/64

etc

1/256

1/1024

1/4096

1/16384

12th term = 1/65536

Answer:

see explanation

Step-by-step explanation:

The common ratio r is calculated as

[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{16}{64}[/tex] = [tex]\frac{1}{4}[/tex]

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 64 and r = [tex]\frac{1}{4}[/tex] , thus

[tex]a_{12}[/tex] = 64 × [tex](\frac{1}{4}) ^{11}[/tex] = 64 × [tex]\frac{1}{4194304}[/tex] = [tex]\frac{64}{4194304}[/tex] = [tex]\frac{1}{65536}[/tex]

Answer:

The length of the window is 18 ft and its height is 14 ft

Step-by-step explanation:

System of Equations

Let's call:

L: Length of the window in feet

W: Width of the window in feet

According to the first condition of the problem:

[tex]L = W + 4\qquad\qquad [1][/tex]

The perimeter of the rectangle is 64 feet. The perimeter is calculated as:

P = 2L + 2W =64

Dividing by 2:

[tex]L + W = 32\qquad\qquad [2][/tex]

The system of equations [1] and [2] can be used to find the dimension of the window.

Substituting from [1]

W + 4 + W = 32

Simplifying:

2W = 32 - 4 =28

Solving:

W = 28/2 = 14

Using [1]:

L = 14 + 4 = 18

The length of the window is 18 ft and its height is 14 ft

Answer:

2.45

Answer:

42

Step-by-step explanation:

3 is equal to 42 degrees because when you have two parallel lines that have another line pass through both parallel lines the values of degrees are the same as the opposite side so:

42 = 3

2 = 4

and another way you could find the value of 3 is since there is a perpendicular line going through line p we know that since it is perpendicular that the angle between them is 90 so angle 3 is:

90 - (angle 4) = angle 3

You may use this method if you first solved for angle 4 or angle 2 and we can get angle 2 from:

180 - 42 = 138

we can do this because 42 + angle two should be 180 degrees since they are along line n.

Step-by-step explanation:

the point (4,3) should be dotted first, start from the (0,0) go right 4 spaces then up 3 spaces. the slope 1/2 means up 1 space then right two spaces to start plotting points on the graph. and to continue the bottom of the line it would be -1/-2 which is down 1 space then left 2 spaces.
