Answer:

49 acres

Step-by-step explanation:

Given that:

Initial coverage = 1200 at midnight

Spread rate = 5√t acres per hour

By how many acres will the fire grow between 6am and 10 am

Hours between (6 - 10) am = 6 hours

Take the integral of the rate function with upper limit = 6 and lower limit = 0

∫5√t dt at t = 6, t = 0

5∫√tdt = 5∫t^1/2 dt at t = 6, t = 0

5 (t^1/2 + 1 / 1/2 + 1) at t = 6, t = 0

5 ( t^3/2 / 3/2) at t = 6, t = 0

5 * 2/3 (t^3/2)

[10/3 *t^3/2] at t = 6, t = 0

(10/3 * 6^3/2) - (10/3 * 0^3/2)

(10/3 * 14.696938) - 0

48.989794

= 49 acres ( approximately)

Answer:

we conclude that only two points (-5, 5) and (-1, 4) satisfy the system of inequalities.

Step-by-step explanation:

Given the system of inequalities

y > 2x+3

y+3x ≤ 1

Checking the point (0, 5)

Let us substittue the point (0, 5) to check if it is satisfies system of inequalities

y > 2x+3

5 > 2(0) + 3

5 > 3

True

now check for the second inequality

y+3x ≤ 1

5 + 3(0) ≤ 1

5 ≤ 1

False

Therefore, the point (0, 5) does not satisfy the system of inequalities

Checking the point (-5, 5)

Let us substittue the point (-5, 5) to check if it is satisfies system of inequalities

y > 2x+3

5 > 2(-5) + 3

5 > -10+3

5 > -7

True

now check for the second inequality

y+3x ≤ 1

5 + 3(-5) ≤ 1

5-15 ≤ 1

-10 ≤ 1

True

Therefore, the point (-5, 5) satisfies the system of inequalities.

Checking the point (-1, 4)

Let us substittue the point (-1, 4) to check if it is satisfies system of inequalities

y > 2x+3

4 > 2(-1) + 3

4 > -2+3

4 > 1

True

now check for the second inequality

y+3x ≤ 1

4 + 3(-1) ≤ 1

4-3 ≤ 1

1 ≤ 1

True

Therefore, the point (-1, 4) satisfies the system of inequalities.

Checking the point (0, -5)

Let us substitute the point (0, -5) to check if it satisfies the system of inequalities

y > 2x+3

-5 > 2(0) + 3

-5 > 0+3

-5 > 3

False

now check for the second inequality

y+3x ≤ 1

-5 + 3(0) ≤ 1

-5+0 ≤ 1

-5 ≤ 1

True

Therefore, the point (0, -5) does not satisfy the system of inequalities.

Checking the point (-3, -3)

Let us substitute the point (-3, -3) to check if it satisfies the system of inequalities

y > 2x+3

-3 > 2(-3) + 3

-3 > -6+3

-3 > -3

False

now check for the second inequality

y+3x ≤ 1

-3 + 3(-3) ≤ 1

-3 - 9 ≤ 1

-12 ≤ 1

True

Therefore, the point (-3, -3) does not satisfy the system of inequalities.

Hence, we conclude that only two points (-5, 5) and (-1, 4) satisfy the system of inequalities.

Answer:

[tex]f(6) = 15[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \left \{ {{|x - 8| + 6 \ x<4} \atop {15\ x\ge 4}} \right.[/tex]

Required

Find f(6)

From the piecewise function, the value of f(x) is:

[tex]f(x) = |x - 8| + 6[/tex]

If [tex]x < 4[/tex]

And the value of f(x) is:

[tex]f(x) = 15[/tex]

If [tex]x \ge 4\\[/tex]

In f(6), the value of x is 6 and [tex]6 \ge 4[/tex]

So, we make use of

[tex]f(x) = 15[/tex]

Substitute 6 for x

[tex]f(6) = 15[/tex]

Answer:

the slope would be 17

Step-by-step explanation:

he earns $17 per hour

you find this by dividing the amount earned by the hours worked

102 / 6 = $17 per hour

187 / 11 = $17 per hour

Answer:

f(x) = 3x² + 1

Step-by-step explanation:

In this question, we need to find what equations equals to 13 when we plug in 2 to x.

Solve the equations to find which one is true:

f(2) = 2² + 8

= 4 + 8

= 12

---------------

f(2) = 3(2)² + 1

= 3(4) + 1

= 12 + 1

= 13

---------------

f(2) = 2(2)³ + 5

= 2(8) + 5

= 16 + 5

= 21

---------------

f(2) = 2² + 2

= 4 + 2

= 6

You will see that the 2nd equation, f(x) = 3x² + 1, is the only one that equals to 13, which makes it correct.

Answer:

10+7+.5

Step-by-step explanation: ez >:)

Answer: 25

Step-by-step explanation:

20/4=5 so 5 books per month then a total of 5 months so 5x5=25

20 divided by 4 is 5 meaning Jackson read 5 books every month so if he read 20 books in 4 months + 5 more months he read a total of 45 books...

5*5=25

25+20=45

Answer:

[tex] m = n = 9\sqrt 2[/tex]

Step-by-step explanation:

Given is a 45° 45° 90° triangle.

So,

[tex]m = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2} \\ \\ n = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2} \\ \\ [/tex]

Answer:

B. ¼.

Step-by-step explanation:

Equation that represents a proportional relationship usually takes the form, y = kx. Where, k is the constant of proportionality.

Therefore, if we are given an equation that represents a proportional relationship, to be y = ¼x, the constant of proportionality is ¼.

Equality Properties

Step-by-step explanation:

Step 1: Define equation

3x + 2 = 17

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 17 does indeed equal 17.

∴ x = 5 is a solution of the equation.

Answer:

[tex]\frac{760}{13}[/tex]  

¡Espero que esto ayude!

Answer:

7 sq rt 2

Step-by-step explanation:

must use pythagorean theorem: square of each leg = square of hypotenuse

7 squared the 7 squared = u squared

49+49=u squared

u = square root of 98, which is sq root of 49 times sq root of 2

8.139 rounded to the nearest tenth would be 8.1 because the tenth place that we’re looking at is the number 1 and the number after it is 3. if the number that is after the tenth place is greater than 5 then the tenth place number goes up. and if the number after tenth place is lower than 5, then we stay the same. since 3 is lower than 5, the tenth place number stays the same making the answer 8.1. hope that helped lol..
