Step-by-step explanation:

Function 1 and the slope is -4/7

=================================================

Explanation:

The slope of y = mx+b is m, which is the number to the left of x.

For function 1

y = (-4/7)x - 4

the slope here is m = -4/7 = -0.57 approximately

Let's use the slope formula to find the slope of function 2 given by the table of values.

Pick any two rows from that table. I'll pick the first two rows.

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

m = (0.8 - 2)/(2 - 0)

m = -0.60

Comparing -0.57 and -0.60, we see that -0.57 is closer to zero on the number line. Meaning that function 1 has the less steep slope (i.e. more shallow slope). The further you go away from zero on the number line, in either direction, the slope will get steeper.

Answer:

25%

Step-by-step explanation:

find the differences between original price $4000 and the altered price $5000.

$5000 - $4000 = $1000

to find the tax percent charged, take the difference price, divide by the original price and multiply with 100, ( to find percentage, it is a must to multiply with 100 ).

1000/4000 x 100

= 25%

so you will get 25 %

Step-by-step explanation:

I guess the meaning is that after 3 more days the week will be over, and she has to reach her goal by then.

x = the average number of miles to ride each of the 3 days

x = (34.1 - 14)/3

the solution is

x = 20.1/3 = 6.7 miles

Answer:

make sure it’s acute

Step-by-step explanation:

since when you measure 90°​ the angle has to be acute

The length of the arc of the QR which is formed in a circle from center P will be equal to 9.9 cm.

The arc of the circle is defined as the product of the angle and the radius of the circle.

[tex]Arc=\theta \times r[/tex]

Now it is given in the question that

circle P, i.e. center is point P.

QS is a diameter with a length of 20 cm so radius =10 cm

Given that RP is the radius with

To find the length of arc QR =?

Now for finding the arc of QR we will find the angle [tex]\angle QPR[/tex] since we have the angle [tex]\angle RPS=123^o[/tex].

[tex]\angle QPR+\angle RPS=180[/tex]

[tex]\angle QPR+123=180[/tex]

[tex]\angle QPR=57^o[/tex]

[tex]\angle QPR=\dfrac{57\times\pi}{180} =0.99\ radian[/tex]

Now the formula for finding the arc will be given by

[tex]Arc \ (QR)=\angle QPR\times r[/tex]

[tex]Arc\ (QR)=0.99\times 10=9.9\ cm[/tex]

Thus the length of the arc of the QR which is formed in a circle from center P will be equal to 9.9 cm.

Answer:

216

Step-by-step explanation:

6 * 6*6 = 216 possible outcomes

The number of outcomes for a rolling of cube three times = 216 outcomes

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

When rolling a six-sided number cube three times, we can calculate the total number of outcomes by considering the number of possible outcomes for each individual roll

Now , For each roll of the number cube, there are six possible outcomes

Since we are rolling the cube three times, we need to multiply the number of outcomes for each roll together:

Number of outcomes = 6 x 6 x 6 = 216

Hence , there will be 216 possible outcomes when rolling a six-sided number cube three times

Answer:

7.4secs

Step-by-step explanation:

If the path of a swim team member is modeled by the equation

h(t) = -0.875t²+5.25t+14

where t is time in seconds and h is the height above the surface of the water

If she need to finish in no later than 5feet above the surface, the expression will become:

-0.875t²+5.25t+14≤5

-0.875t²+5.25t+14-5≤0

-0.875t²+5.25t+9≤0

Rewriting using fraction

-7/8t²+21/9t+9≤0

To get the time that this happens we will need to factorize the resulting expression above;

On factorising

Find the roots of the equation using the formulas

t = 3+3√105/7

t = 3+ 3(10.25)/7

t = 3 + (30.75)/7

t = 3 + 4.393

t = 7.393

t = 7.4secs

Hence this happens at t = 7.4secs

Answer:

The time when the swim team member is 5 feet above the water surface is 7.4 seconds.

Step-by-step explanation:

You want to know when a member of the swim team finished his jump no later than 5 feet above the surface of the water to prepare for the splash, that is, when t is 5 feet above the surface of the water. Substituting h(t) for this value 5 in the equation you obtain:

5= -0.875*t²+5.25*t+14

A quadratic equation has the general form:

a*x² + b*x +c= 0

where a, b and c are known values ​​and a cannot be 0.

Taking the equation 5= -0.875*t²+5.25*t+14 to that form, you get:

 -0.875*t²+5.25*t+14-5=0

  -0.875*t²+5.25*t+9=0

The roots of a quadratic equation are the values ​​of the unknown that satisfy the equation. And solving a quadratic equation is finding the roots of the equation. For this you use the formula:

[tex]\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]

In this case, solving the equation is calculating the values ​​of t, that is, you find the time when the swim team member is 5 feet above the water surface.

Being a= -0.875, b=5.25 and c= 9, then

[tex]\frac{-5.25+-\sqrt{5.25^{2}-4*(-0.875)*9 } }{2*(-0.875)}[/tex]

[tex]\frac{-5.25+-\sqrt{27.56+31.5 } }{-1.75}[/tex]

[tex]\frac{-5.25+-\sqrt{59.06 } }{-1.75}[/tex]

[tex]\frac{-5.25+-7.685}{-1.75}[/tex]

Then:

[tex]t1=\frac{-5.25+7.685}{-1.75}[/tex] and [tex]t2=\frac{-5.25-7.685}{-1.75}[/tex]

Solving for t1:

[tex]t1=\frac{2.435}{-1.75}[/tex]

t1= -1.39 ≅ -1.4

Solving for t2:

[tex]t2=\frac{-12.935}{-1.75}[/tex]

t2= 7.39 ≅ 7.4

Since time cannot be negative, the time when the swim team member is 5 feet above the water surface is 7.4 seconds.

Answer:

x = 4 ± [tex]\sqrt{5}[/tex]

Step-by-step explanation:

to find the solutions equate the quadratic to zero

x² - 8x + 11 = 0 ( subtract 11 from both sides )

x² - 8x = - 11

solve using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = - 11 + 16

(x - 4)² = 5 ( take square root of both sides )

x - 4 = ± [tex]\sqrt{5}[/tex] ( add 4 to both sides )

x = 4 ± [tex]\sqrt{5}[/tex]

Answer:

Answer:

False.

Step-by-step explanation:

Think of the number 12 which is 2 * 2 * 3.

Now square 12 to 144.

144 is a perfect square since it is the square of 12.

144 = 2 * 2 * 2 * 2 * 3 * 3

What are the factors of 144?

1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144.

That is a lot more than 3 factors.

Based on the scholarships and grants that Jamal will receive, his estimated cost per year is $25,050.

If his family contributes $21,000, he will have to contribute $4,050.

If Jamal has $0 in savings, the amount to save each month is $337.50.

If Jamal has $1,000 in savings, the amount to save each month is $254.17.

If Jamal has $2,000 in savings, the amount to save each month is $170.83.

= Cost per year of private university - Scholarships - Work study program

= (25,100 + 8,000 + 1,300 + 750) - 8,200 - 1,900

= 35,150 - 8,200 - 1,900

= $25,050

= Estimated cost - family contribution

= 25,050 - 21,000

= $4,050

The amount that Jamal should save monthly can be found as:

= (Amount to contribute - Amount already saved ) / Number of months in year

If Jamal has $0, he should save:

= (4,050 - 0) / 12

= $337.50

If Jamal has $1,000:

= (4,050 - 1,000) / 12

= $254.17

If Jamal has $2,000:
= (4,050 - 2,000) / 12

= $170.83
