Answer:

b should be the answer

Step-by-step explanation:

Answer:

C is the correct answer

Step-by-step explanation:

I know thus because you go down 5/10 every time and 5/10 as a decimal is 0.5 which means the slope is -0.5

Answer:

the answer is y=3x+9 if you are looking for it to be in slope intercept form

Answer:

The values of b are [tex]\mathbf{b=\pm18}[/tex]

Step-by-step explanation:

We need to find the value of b will cause [tex]27x^2+ bx +3 = 0[/tex] to have one real solution.

If it has one real solution, the discriminant is zero.

The formula of discriminant is: [tex]b^2-4ac[/tex]

In our case: [tex]b^2-4ac=0[/tex]

We have a=27, b=b and c=3

Putting values to find b

[tex]b^2-4ac=0\\b^2-4(27)(3)=0\\b^2-324=0\\b^2=324\\Taking \ square root \ on \ both \ sides\\\sqrt{b^2}=\sqrt{324}\\b=\pm18[/tex]

So, the values of b are [tex]\mathbf{b=\pm18}[/tex]

Answer:

A

Step-by-step explanation:

- to find x we use tan 60 = x/7

- rearrange, tan60*7 = x, x = [tex]7\sqrt{3}[/tex]

- now you have two sides so you can use pythagoras  to find z

y^2 + x^2 = z^2

z = [tex]\sqrt{(7\sqrt{3})^2 + (7)^2 }[/tex]

z = 14

Step-by-step explanation:

5 feet = 60 inches

Sarah needs to grow 6 more centimeters.

Answer: So since 5 feet equals 60 inches and 1 inch is about 2.54 centimeters, there are centimeters in 5 feet. Therefore, Sarah needs to grow 6 more centimeters to reach 5 feet. I hoped this helps!! :D

Step-by-step explanation:

Answer:

4.8 hours

Step-by-step explanation:

20% of 24 hours is the product of the decimal form of 20% (which is 0.2) times 24.

The answer is:

0.2 * 24 = 4.8 hours which is the same as 4 hours and 48 minutes.

Answer:

[tex]S_{1893} =5632.98[/tex]

Step-by-step explanation:

The correct form of the question is:

[tex]S = 1.001^{1892} + ... + 1.001^2 + 1.001 + 1[/tex]

Required

Solve for Sum of the sequence

The above sequence represents sum of Geometric Sequence and will be solved using:

[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]

But first, we need to get the number of terms in the sequence using:

[tex]T_n = ar^{n-1}[/tex]

Where

[tex]a = First\ Term[/tex]

[tex]a = 1.001^{1892}[/tex]

[tex]r = common\ ratio[/tex]

[tex]r = \frac{1}{1.001}[/tex]

[tex]T_n = Last\ Term[/tex]

[tex]T_n = 1[/tex]

So, we have:

[tex]T_n = ar^{n-1}[/tex]

[tex]1 = 1.001^{1892} * (\frac{1}{1.001})^{n-1}[/tex]

Apply law of indices:

[tex]1 = 1.001^{1892} * (1.001^{-1})^{n-1}[/tex]

[tex]1 = 1.001^{1892} * (1.001)^{-n+1}[/tex]

Apply law of indices:

[tex]1 = 1.001^{1892-n+1}[/tex]

[tex]1 = 1.001^{1892+1-n}[/tex]

[tex]1 = 1.001^{1893-n}[/tex]

Represent 1 as [tex]1.001^0[/tex]

[tex]1.001^0 = 1.001^{1893-n}[/tex]

They have the same base:

So, we have

[tex]0 = 1893-n[/tex]

Solve for n

[tex]n = 1893[/tex]

So, there are 1893 terms in the sequence given.

Solving further:

[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]

Where

[tex]a = 1.001^{1892}[/tex]

[tex]r = \frac{1}{1.001}[/tex]

[tex]n = 1893[/tex]

So, we have:

[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{1 -\frac{1}{1.001} }[/tex]

[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{\frac{1.001 -1}{1.001} }[/tex]

[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{\frac{0.001}{1.001} }[/tex]

[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001^{1893}})}{\frac{0.001}{1.001} }[/tex]

Simplify the numerator

[tex]S_{1893} =\frac{1.001^{1892} -\frac{1.001^{1892}}{1.001^{1893}}}{\frac{0.001}{1.001} }[/tex]

[tex]S_{1893} =\frac{1.001^{1892} -1.001^{1892-1893}}{\frac{0.001}{1.001} }[/tex]

[tex]S_{1893} =\frac{1.001^{1892} -1.001^{-1}}{\frac{0.001}{1.001} }[/tex]

[tex]S_{1893} =(1.001^{1892} -1.001^{-1})/({\frac{0.001}{1.001} })[/tex]

[tex]S_{1893} =(1.001^{1892} -1.001^{-1})*{\frac{1.001}{0.001}}[/tex]

[tex]S_{1893} =\frac{(1.001^{1892} -1.001^{-1}) * 1.001}{0.001}[/tex]

Open Bracket

[tex]S_{1893} =\frac{1.001^{1892}* 1.001 -1.001^{-1}* 1.001 }{0.001}[/tex]

[tex]S_{1893} =\frac{1.001^{1892+1} -1.001^{-1+1}}{0.001}[/tex]

[tex]S_{1893} =\frac{1.001^{1893} -1.001^{0}}{0.001}[/tex]

[tex]S_{1893} =\frac{1.001^{1893} -1}{0.001}[/tex]

[tex]S_{1893} =5632.97970294[/tex]

Hence, the sum of the sequence is:

[tex]S_{1893} =5632.98[/tex] ----- approximated

Answer:

3 adult tickets and 4 child tickets

Step-by-step explanation:

a + k = 7

a = 7 - k

12a + 9k = 72

12a + 9k = 72

12(7 - k) + 9k = 72

84 - 3k = 72

84 - 3k = 72

3k = 12

k = 4

a = 3

The number of adult tickets purchased is 3 and the number of child tickets purchased is 4.

Given that, adult tickets cost $12 and child tickets cost $9.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

If they spent $72 total and purchased 7 tickets.

Let the number of adult tickets be x, then the number of children tickets will be 7-x.

Now, 12x+9(7-x)=72

⇒ 12x+63-9x=72

⇒ 3x=72-63

⇒ 3x=9

⇒ x=3

So, 7-x=4

Therefore, the number of adult tickets purchased is 3 and the number of child tickets purchased is 4.

Answer: y=1/3x-2

Step-by-step explanation:

To find the equation of the line, we need the slope and y-intercept. To find the slope, we can take any two points on the graph and use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. To find the y-intercept, we find the point that crosses the y-axis. The two points on the graph are (0,-2) and (3,-1).

[tex]m=\frac{-1-(-2)}{3-0} =\frac{1}{3}[/tex]

Now, we know the slope is 1/3.

The graph crosses the y-axis at (0,-2). Therefore the y-intercept is -2. This tells us that the equation is y=1/3x-2.

Answer:

A,C,E.

Step-by-step explanation:

slope=(-12-0)/(4-0)=-3

A.The slope is proportional.

C. Slope is negative.

E. The eq. of line is y=-3x
