Answer:

B. 1,500’

Step-by-step explanation:

Given;

dimension of the rectangular house, = 35’ x 40’

The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'

The rough estimate should be greater than the actual estimate in 100s;

rough estimate = 1,400' + 100' = 1,500'

Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.

Answer:

The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].

Step-by-step explanation:

The only function whose inverse is also a function is the linear function, also named first-order polynomial. The inverse of a linear function is also a linear function. That is:

[tex]y = \frac{1}{3}\cdot x -\frac{3}{4}[/tex]

[tex]\frac{1}{3}\cdot x = y + \frac{3}{4}[/tex]

[tex]x = 3\cdot y + \frac{9}{4 }[/tex]

The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].

Answer:

The cost of 432 meters square = $21924

Step-by-step explanation:

The length of the plot = l = 27m

The width of the plot = w = 16m

We know that the area of a rectangular object can be determined by multiplying the length and width.

Thus, the area of the rectangular vegetable plot will be:

[tex]A = wl[/tex]

substituting w = 16 and l = 27

A = 16 × 27

A = 432 m²

Therefore, the vegetable plot will be:

A = 432 meter square

Given

The cost of ploughing field of 1 meter square =  $50.75

so

The cost of ploughing field 432 meters square = 50.75 × 432

                                                                               = $21924

Therefore, the cost of 432 meters square = $21924

Answer:

Larissa takes 59.141 seconds to complete both laps.

Step-by-step explanation:

The complete time is the sum of time taken on each lap. We translate the two statements into mathematical expressions to determine the required output:

(i) She completes her first lap in 31.135 seconds:

[tex]x_{1} = 31.135\,s[/tex]

(ii) She completes her second lap 3.129 seconds faster than the first lap:

[tex]x_{2} = x_{1}-3.129\,s[/tex]

[tex]x_{2} = 31.135\,s - 3.129\,s[/tex]

[tex]x_{2} = 28.006\,s[/tex]

Then, the time taken by Larissa to complete both laps is:

[tex]\Delta x = x_{1} + x_{2}[/tex]

[tex]\Delta x = 31.135\,s+28.006\,s[/tex]

[tex]\Delta x = 59.141\,s[/tex]

Larissa takes 59.141 seconds to complete both laps.

[tex]7 \frac{26}{15}[/tex]

Step-by-step explanation:

[tex]8 \frac{11}{15} = 7 \frac{?}{15}[/tex]

Remember the multiply and add rule or improper fractions. To convert from a mixed number to an improper fraction, one must multiply the number part of the mixed number by the bottom (denominator) on the fraction. Then one must add that to the numerator (top) of the fraction. Since 7 is 1 less than 8, then one would have to multiply 15 by 1, and add it to 11, to get the value on top of [tex]7 \frac{?}{15}[/tex] The value would be;

Step-by-step explanation:

The graph of the function is a V-shaped curve.

Given that we need to determine the graph of the function f(x) = 7|x - 4| - 1.

To graph the function f(x) = 7|x - 4| - 1, you can follow these steps:

Start by identifying the key points of the function. In this case, the function involves an absolute value, which means it may change direction at the point inside the absolute value.

Set the expression inside the absolute value equal to zero and solve for x to find this critical point:

|x - 4| = 0

x - 4 = 0

x = 4

So, the critical point is x = 4.

Next, consider the behavior of the function on each side of the critical point.

Choose some values of x less than and greater than 4 and substitute them into the function to determine the corresponding y-values.

Let's choose x = 2:

f(2) = 7|2 - 4| - 1

f(2) = 7|-2| - 1

f(2) = 7(2) - 1

f(2) = 14 - 1

f(2) = 13

Let's choose x = 6:

f(6) = 7|6 - 4| - 1

f(6) = 7|2| - 1

f(6) = 7(2) - 1

f(6) = 14 - 1

f(6) = 13

Therefore, we have the points (2, 13) and (6, 13) on the graph.

Plot the critical point and the points you found on the coordinate plane. Mark them on the x-axis and y-axis.

To graph the absolute value part of the function, draw a V-shaped curve with the vertex at the critical point (4, 0).

The arms of the V-shaped curve will pass through the plotted points (2, 13) and (6, 13).

Extend the arms of the V-shaped curve indefinitely in both directions.

Finally, add the constant term (-1) by shifting the entire graph down by 1 unit. This means that every y-value on the graph should be reduced by 1 unit.

Your completed graph of the function f(x) = 7|x - 4| - 1 should resemble a V-shaped curve with its vertex at (4, -1), passing through the points (2, 12) and (6, 12), and extending infinitely in both directions.

The graph of the function is attached.

22.5/9=2.5

Answer:

Step-by-step explanation:

All the angles that have a cosine of 9/15 are,

⇒ ∠P and ∠X

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Triangle PQR is similar to triangle XYZ.

Hence, We get;

In triangle PQR,

cos P = 9/15

And, In triangle XYZ,

cos X = XZ / ZY

cos X = 9 / 15

Answer: y=0.5x-6. She forgot the y-intercept

Step-by-step explanation: use the slope formula to get the slope of 0.5 and just add in the y-intercept of -6 since:

Answer:

Ricky had 1205 hits. Pedro had 1481 hits.

Step-by-step explanation:

Set variables.

Set up an equation.

Pedro and Ricky got 2686 base hits total.

Pedro had 276 more hits than Ricky.

Plug p into your first equation.

Combine like terms.

Divide both sides by 2 to isolate r.

You now know that Ricky had 1205 hits. Pedro had 276 more hits than Ricky. Therefore,

Pedro had 1481 hits.

Check your work.

total hits = Pedro's + Ricky's

2686 = 1481 + 1205

2686 = 2686

Pedro's hits = Ricky's hits + 276

1481 = 1205 + 276

1481 = 1481
