Answer:

Step-by-step explanation:

B

theres no constant so its y intercept is (0,0)

then the x is negative so it goes down from left to right

Answer: On interval f(x) is increasing =  [tex]( -\infty, -2)[/tex]

On interval f(x) is decreasing = [tex]( -\infty, -2)[/tex]

Step-by-step explanation:

The given function: [tex]f(x)=-(x+2)^2+4[/tex]

The graph of the function is attached below

In graph , function is increasing till point (-2,4) or x=-2 and then it is decreasing.

So f(x) is increasing in [tex]( -\infty, -2)[/tex] and decreasing in [tex](-2, \infty)[/tex]

So, On interval f(x) is increasing =  [tex]( -\infty, -2)[/tex]

On interval f(x) is decreasing = [tex]( -\infty, -2)[/tex]

Answer:

m = 16

Step-by-step explanation:

2(4m - 5) - (6m - 11) = 33 (Given)

8m - 10 - 6m + 11 = 33 (Distribute)

2m + 1 = 33 (Combine like terms)

2m = 32 (Subtract 1 on both sides)

m = 16 (Divide 2 on both sides)

You can check by substituting your answer into the equation:

2(4(16) - 5) - (6(16) - 11) = 33

2(64 - 5) - (96 - 11) = 33

2(59) - (85) = 33

118 - 85 = 33

33 = 33

Answer: y = 3, x = 5

Step-by-step explanation:

Solution by substitution method

4x+y=23

3x-y=12

Suppose,

4x+y=23→(1)

and 3x-y=12→(2)

Taking equation (1), we have

4x+y=23

⇒y= -4x+23→(3)

Putting y= -4x+23 in equation (2), we get

3x-y=12

3x-1(-4x+23)=12

⇒3x+4x-23=12

⇒7x-23=12

⇒7x=12+23

⇒7x=35

⇒x=5→(4)

Now, Putting x=5 in equation (3), we get

y=-4x+23

⇒y=-4(5)+23

⇒y=-20+23

⇒y=3

∴y=3 and x=5

Answer:

Amount spent after sales tax = $112.58

Step-by-step explanation:

Given that:

Cost of jacket = $49.00

Cost of new Vans = $55.00

Total spent = 49.00 + 55.00 = $104.00

Sales tax = 8.25%

Amount of sales tax = [tex]\frac{8.25}{100}*104[/tex]

Amount of sales tax = $8.58

Total after sales tax = 104.00 + 8.58 = $112.58

Hence,

Amount spent after sales tax = $112.58

Answer:

sqrt 58

Step-by-step explanation:

7^2+3^2=c^2

c=[tex]\sqrt{58}[/tex]

Answer:

sqrt(58)

Step-by-step explanation:

Use the Pythagorean Theorem.

a^2 + b^2 = c^2

3^2 + 7^2 = c^2

9 + 49 = c^2

58 = c^2

c = sqrt(58)

any number that isnt a fraction or decimal :)

Answer:

See below.

Step-by-step explanation:

1.

3x + 7 + 10x + 17 = 180  ( property of inside angles of 2 parallel lines)

13x + 24 = 180

13x = 180 - 24 = 156

c = 156/13

x = 12.

As the triangle is a right triangle:

42.7 + N = 90

N = 90 - 42.7

= 47.3. degrees.

Answer:

for the first question it will be

Step-by-step explanation:

first make the equation from the numbers you see, (3x+7)+(10x+17)=180

the 180 comes from the lines that the equations are on both of the equations add up to 180 degrees,

then first add all like numbers [(3x+10x) + (7+17) = 180]= 13x+24=180

next subtract the non-variable number (forgot the term for it)

13x+24=180

     -24  -24

      13x=156

then divide the number in front of the variable

13x=156

13    13

x=12

then once you divide the answer is shown so you can put it in

Question:

Leah took her friends for a ride in her hot air balloon.

The function r(t) = 210 - 15t models the height of the hot air balloon about the ground (in meters) as a function of time (in minutes) after takeoff.

Explain what r(10) means in the context of the real-world scenario, and how to find its value.

Answer:

The balloon reaches a height of 160 meters, 10 minutes after take off.

Step-by-step explanation:

Given

[tex]r(t) = 210 - 5t[/tex]

Required

Explain r(10)

First, we calculate r(10)

Substitute 10 for t in [tex]r(t) = 210 - 5t[/tex]

[tex]r(10) = 210 - 5 * 10[/tex]

[tex]r(10) = 210 - 50[/tex]

[tex]r(10) = 160[/tex]

Hence: r(10) means that the balloon reaches a height of 160 meters, 10 minutes after take off.

The answer is 3.785, but rounding it to the nearest hundredth is 3.68 or 3.79, depending on rather they wanted you to take the t and round up or just leave it off.

The jug hold the amount of 3.77 liters of milk.

To find out how many liters of milk the jug holds, we can use the conversion factor that 1 L is equal to 1.06 qt.

Given that the jug of milk holds 4 quarts, we can convert this to liters by multiplying it by the conversion factor:

4 quarts x (1 L / 1.06 qt)

= 3.77 liters

Thus, the jug holds 3.77 liters of milk.

Answer: 348

Step-by-step explanation:

Given : Total employees work = 725

Proportion of employees are post graduate = 52%

Proportion of employees are not post graduate = 100%-52% = 48%

The number of employees were not post graduate  = 48% of 725

= 0.48 x  725

= 348

Hence, the number of employees were not post graduate  = 348
