$\huge \bold \green{Question}$

A scientist has collected the following data on the population of a bacteria colony over a thirty-minute period:

5 minutes: 78,000

10 minutes: 234,000

15 minutes: 657,000

20 minutes: 1,784,000

25 minutes: 5,040,000

30 minutes: 14,980,000

Which type of graph would be best to use to display the growth of the colony?

A.) a bar graph

B.) a circle graph

C.) a histogram

D.) a line graph

$\huge \bold \red{Answer}$

An bar graph suits the best in this type of study because we can easily understand the growth and decrease of that particular thing which is being studied.

Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. Whi

Romashka [77]

Answer:

$\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3$

Step-by-step explanation:

The x-intercepts are the values of x for which y=0, that is f(x)=0.

The x-intercepts of

$\bf f(x)=4x^2-24x+20$

are the values of x such that

$\bf 4x^2-24x+20=0$

Divide both sides by 4 to simplify a little

$\bf x^2-6x+5=0$

Solve the quadratic equation

$\bf x=\displaystyle\frac{-(-6)\pm\sqrt{(-6)^2-4*1*5}}{2*1}=\displaystyle\frac{6\pm\sqrt{36-20}}{2}=\\\\=\displaystyle\frac{6\pm\sqrt{16}}{2}=\displaystyle\frac{6\pm4}{2}$

and you get the 2 x-intercepts

x =10/2 and x = 2/2

x = 5 and x = 1

The average is the midpoint

$\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3$

X - m = p + n solve for x

Eva8 [605]

Answer: ⇒ x=m+n+p

____________________________________________________

Step-by-step explanation:

First you had to add by m from both sides of equation.

$-m+x+m=n+p+m$

$x=m+n+p$

Kate is at a T-shirt sale where she can buy one and get a second one for 30% off. She wants to buy two T-shirts listed at $19 ea

gladu [14]

So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. And how much will she pay?

Solution: 
1. 19 for each t-shirt 
2. Total of $38 if not provided with 30% off
3. 19 x 0.3 = 5.7
4. Hence 30% of $19 is $5.7
5. Next is we deduct $5.7 which is 30% of $19. 
6. 19 – 5.7 = $13.3 
7. Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3. 
8. 19 + 13.3 = 32.3
9. Conclusively, she will pay $32.3 for the shirts.

Can anyone help? If arcLM = 8x-56 and arcNP = 5x+22, find arcLP.

Mashcka [7]

Answer:

arcLP = 19

Step-by-step explanation:

Given the following

arcLM = 8x-56

arcNP = 5x+22

Required

arcLP

Given that arcLM = arcNP

8x-56 = 5x+22

8x - 5x = 22 + 56

3x = 78

x = 78/3

x = 26

Let assume arcLP = x - 7

arcLP = 26 -7

arcLP = 19
