A.564

B.420

C.427

D.394

C. 427

The median is the middle number of all the data

Since there is an even number of data points the median is in between the middle two data points (434 and 420)

To find this: 434-420=14

14/2=7

434-7=427

**Answer:**

See answer below.

**Step-by-step explanation:**

P(v) = -4v³ + 12v² - 9v

Point (-5, -845) is not a point on the graph

P(-5) = -4(-5)³ + 12(-5)² - 9(-5)

P(-5) = 500 + 300 + 45

P(-5) = 800 + 45

P(-5) = 845 point (-5, 845) is a solution

Write the equation of the graph shown below in factored form. a graph that starts at the top left and continues down through the x axis at one to a minimum around y equals negative zero point six and goes up to cross the x axis two to a maximum around y equals zero point two and and then goes back down to a touch the x axis at three and then goes back up to the top right. f(x) = (x − 3)2(x + 2)(x − 1) f(x) = (x + 3)2(x − 2)(x + 1) f(x) = (x + 3)2(x + 2)(x + 1) f(x) = (x − 3)2(x − 2)(x − 1)

**Answer:**

(d) f(x) = (x − 3)^2(x − 2)(x − 1)

**Step-by-step explanation:**

In this context, a crossing of the axis at x=p means there is a factor of (x-p). A "touch" of the axis at x=q means there is a factor of (x -q)^2.

A crossing at x=1 and x=2, and a touch at x=3 means the factors are ...

Rafael runs 7 miles in 60 minutes. at the same rate, how many miles would he run in 24 minutes

**Answer:**

2.8 miles

**Step-by-step explanation:**

Time for next run = 24 min

Length of the next run = 7/60 miles/min *24 min = 2.8

Veronica traveled 562 miles to Venice, Florida. She drove 85 miles every day. On the last day of her trip, she only drove 52 miles. Write and solve an equation to find the number of days veronica traveled.

Answer:

562 = 85x +52

x is the number of days

Veronica traveled for 7 days

Step-by-step explanation:

562 = 85x + 52

510 = 85x Subtract 52 on both sides

6 = x Divide by 85 to isolate x

Even though Veronica only had to drive 52 miles on the last day of her trip, it still counts as a day of driving. Hence, she traveled 7 days in total.

It requires 350 joules to raise a certain amount of a substance from 10. 0Â°C to 30. 0Â°C. The specific heat of the substance is 1. 2 J/gÂ°C. What is the mass of the substance? 12 g 15 g 18 g 30 g.

The correct option is **B** which is** 15 g**.

Given to us:

the heat [tex]Q= 350\ Joules[/tex],

the **specific heat** [tex]c= 1.2\ J/g\ ^o C[/tex],

the **lower temperature **[tex]t_1= 10^o C[/tex],

the **higher **temperature [tex]t_2= 30^o C[/tex],

Formula for **specific heat**:

[tex]Q=mc(\Delta T)[/tex]

where,

[tex]m[/tex] is the mass,

[tex](\Delta T)[/tex] is the **temperature difference**,

Putting in the values;

[tex]350=m\times 1.2\times (30-10)\\\\m= \dfrac{350}{1.2\times (30-10)} \\\\m=14.5833 grams[/tex]

Hence, the **mass **is 14.5833 grams. therefore, the correct option is B which is** 15 g**.

Elizabeth lives on a straight road that goes east and west. She starts from a point 5.8 miles west of her home and drives a certain distance to the store. The store is more than 434 miles east of her home.

Let d represent the distance Elizabeth drove.

Which inequality represents this situation?

**Answer:**

−5.8+d>43/4

**Step-by-step explanation:**

The **inequality **represents the **situation **as −5.8+d>434.

When two **expressions **are connected by a sign like "not equal to," "**greater **than," or "less than," it is said to be inequitable. The inequality shows the greater than and **less **than relation between variables and the numbers.

A line passes through (3,7) and (5,9). Write the equation of the

line in slope-intercept form.

**Answer:**

y = x+4

**Step-by-step explanation:**

First, we find the slope

m = (y2-y1)/(x2-x1)

m = ( 9-7)/(5-3)

= 2/2

=1

Slope intercept form of a line is y = mx+b where m is the slope and b is the y intercept

y = 1x+b
