Answer:

4.5 feet

Step-by-step explanation:

Here, we are concerned with calculating the actual height in feet of the door given the scale used in the maps drawing.

In the scale, scale to actual is 1 inch to 2.5 feet

let 1.8 inch scale = x actual feet

Thus mathematically, by cross multiplying; we have;

x = 2.5 * 1.8 = 4.5 feet

How many integers are between sqrt 37 and 5*sqrt 11?
34kurt

Answer:

There are 10 integers between the given values

Step-by-step explanation:

We start by finding approximations of the two real values given that include square roots of non-perfect-square numbers:

\sqrt{37} \approx6.0827

then this point is located in between the integers 6 and 7 on the x-axis.

5\,\sqrt{11} \approx 16.58

therefore, it is located between the integers 16 and 17 on the number line.

Then between \sqrt{37}, and 5\,\sqrt{11}, we have the following integers:

7, 8, 9, 10, 11, 12, 13, 14, 15, 16.

That is 10 integers

Determine the line that is parallel to y 2x+5 and passes through the point (2,3).
hodyreva [135]
Parallel lines have the same gradient so it’s the second or the fourth answer.

y = mx + c
y = 2x + c
3 = (2 x 2) + c
3 = 4 + c
3 - 4 = c
c = -1

y = 2x - 1

The graph of the function, B(x), is shown below. Determine the following values for the function:
Softa [21]

Answer:

B(-1) = 1\\\\B(3) = 0\\\\B(1) =2  

Step-by-step explanation:

By definition, a relation is a function if each input value has one and only one output value.

The input values are the x-values and the output values are the y-values.

Given:

B(-1),B(3) and B(1)

We can identify that we need to find the output values of these input values:

x=-1\\x=3\\x=1

Observe in the graph attached that:

  • When x=-1,\ y=1
  • When x=3,\ y=0
  • When x=1,\ y=2  

Therefore:

B(-1) = 1\\\\B(3) = 0\\\\B(1) =2
