Answer:

√181 units

Step-by-step explanation:

P(x1,y1)=(8,6)

P(x2,y2)=(-2,-3)

steps are in the picture above.

Step-by-step explanation:

Solution,

f(x) = -4x2 + 19

f(x)=-8+19

f(x)=27

As it is a constant function, therefore

f(-7)=27

Jake's answer is true; the change in temperature is -7.9° F.

Step-by-step explanation:

The change in temperature is the final value minus the initial value. Evening minus the morning.

The final value is 15.6° F, the initial value is 23.5° F.

So 15.6 - 23.5 = -7.9

Step-by-step explanation:

First you divide the number of clicks by seconds.

36÷5=7.2

26÷3=8.6

Now you know how much clicks the bots do in 1 second

Bot#3= 7.2

Bot#4= 8.6

Now multiply by 10.

Bot#3= 72

Bot#4= 86

Bot#4 does more clicks in 10 seconds.

Answer:

x=5 since if anything smaller than 0 it would be an imaginary number and would not be a real output

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

the function of f(x) = √(x – 5) + 2 will have real outputs , since √(x-5) ≥ 0

=> x - 5 ≥ 0

=> x ≥ 5

so, the input value begin from 5

Answer:

-5

Step-by-step explanation:

We can use the slope formula to find the slope

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

     =(-12 -8)/(3 - -1)

    =(-12-8)/(3+1)

   = -20/4

   = -5

Answer:

PQ=12

QR= 8

Hope it helps.

Answer: PQ = 12

QR = 8

Step-by-step explanation:

3x + 6 + 2x+4 = 20

5x = 20- 10

so, x = 2

so

PQ = 3x + 6 = 3*2+6 = 6+6 = 12

QR = 2x+4 = 2*2+4 = 4+4 = 8

An income is taxable is such income falls into a category where a proportion of the income is removed, as tax. To have an extra $5000 after tax, Tara must save $6173.

Given that:

[tex]Earnings = \$20000[/tex] --- normal earnings

[tex]Amount = \$5000[/tex] ---- the amount needed

From the complete question, the tax rate for earnings between $18201 and $37000 is 19%.

Let the additional amount be x.

So, the equation that calculates the amount needed (after tax) is:

[tex]x(1 - 19\%) = 5000[/tex]

Express as decimal

[tex]x(1 - 0.19) = 5000[/tex]

[tex]x(0.81) = 5000[/tex]

Make x the subject

[tex]x = \frac{5000}{0.81}[/tex]

[tex]x = \$6173[/tex]

Hence, she needs to make an extra of $6173 to save $5000

Answer:

183 divided by 3 = miles per hour

183 / 3 = 61

61 mph

Answer:

61

Step-by-step explanation:

To find unit rate, divide the amount of length to the time. In this instance, 183 miles is the length and 3 hours is the time.

Divide:

183/3 = 61

So, there are 61 miles in 1 hour.

Answer:

170.25

Step-by-step explanation:

I made 15% into a decimal. The decimal, being 0.15, was multiplied to 1135 to get the answer 170.25

1135 x 0.15 = 170.25

The value of the percentage is,

→ 15 ÷ 100

→ 0.15

We have to find,

→ 15% of 1135

Let's find the solution,

→ 1135 × 0.15

→ 170.25

Hence, the answer is 170.25.

UNIT OF MEASURE

BASED ON LANE

1

To begin, you must do Steps 1-3 to enter (or verify) the correct information for the track being used. Frequently-used values have been pre-entered in all three steps. Change them only if required.

Step 1. ENTER THE TRACK SIZE (i.e., the distance covered when completing one lap - normally in Lane 1) and select the unit of measure.

 most outdoor tracks are either 400 meters or 440 yards (4 laps to a mile)

 most indoor tracks are either 200 meters or 220 yards (8 laps to a mile)

See NOTE 3 for determining track size. Also note that a very small number of tracks use a lane other than Lane 1 to define the track size (see NOTE 4). If the size you entered is not based on Lane 1, select the lane number upon which the size is based.

Step 2. ENTER THE LANE WIDTH of lanes on the track (they should all be the same width). While the best tracks (IAAF, Olympic, etc.) have lanes that are 1.22m to 1.25m wide, most high school and college tracks have lane widths measured in inches (e.g., 42"). See NOTE 5 for information on how to measure lane width. LANE WIDTH

42

Step 3. IS THERE A RAISED CURB on the inside of Lane 1 (normally 2" - 2.5" high)? If there is, select "yes." If the inside edge of Lane 1 is defined only by a painted line, select "no." See NOTE 6 for further information about curbs.

no

After noting (or printing) the results, enter different parameters for the same calculation or proceed to another calculation section.

The equation after simplification is [tex]7x^{6}+42x^{2} -152=0[/tex].

Simplification of an equation is the process of writing an equation in the most efficient and compact form without affecting the value of the original equation. It involves, multiply out the brackets and then simplify the resulting equation by collecting the like terms.

For the given situation,

The equation is

[tex]7x^{6}=2[{45-3(7x^{2} -15+6)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-3(7x^{2} -9)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-21x^{2} +27}+4][/tex]

⇒ [tex]7x^{6}=2[-21x^{2} +76][/tex]

⇒ [tex]7x^{6}=-42x^{2} +152[/tex]

⇒ [tex]7x^{6}+42x^{2} -152=0[/tex]

Hence we can conclude that the simplified equation is [tex]7x^{6}+42x^{2} -152=0[/tex].
