Which linear function represent the table?

rodikova [14]

Answer:

Step-by-step explanation:So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function. This rate of change is called the slope.Mar 9, 2011

I just need sum help:( and a tutor

seraphim [82]

Answer:

The forth answer.

Try also transformation of curves bite (size) page.

I think it would reflect y less than x as we start x^2 for f(x) and usually 1 or 2 is the answer in quadratics. Once we have found y we can work out x

The length of a bridge on a map is 1.5 cm. What is the actual length of the bridge in meters if the map is drawn at a scale of 1

Vitek1552 [10]

Answer:

The actual length of the bridge is 600 meters

Step-by-step explanation:

we know that

The scale on a map is

$\frac{1}{40,000}$

That means

1 unit on a map represent 40,000 units in the actual

1 cm on a map represent 40,000 cm in the actual

Remember that

$1/ m=100/ cm$

so

$40,000\ cm=40,000/100=400\ m$

we can rewrite the scale as

$\frac{1}{400}\frac{cm}{m}$

using proportion

Find out the actual length of the bridge in meters if the length of a bridge on a map is 1.5 cm.

Let

x ----> the the actual length of the bridge in meters

$\frac{1}{400}\frac{cm}{m}=\frac{1.5}{x}\frac{cm}{m}\\\\x=400(1.5)\\\\x=600\ m$

A. Write the formula for the area A of a trapezoid. Use b1 and b2 for the lengths of the bases, and use h for the height.

lesya692 [45]

Answer:

(a) The formula for the area A of a trapezoid

$A = \frac{1}{2}(b_{1}+ b_{2})h$

(b) Solve the formula for h

$h = \frac{2A}{b_{1}+b_{2}}$

(c) Find the height h of the trapezoid

The height h of the trapezoid is 6 cm.

Step-by-step explanation:

(a) The formula for the area A of a trapezoid

As b₁, b₂ being the lengths of the bases and 'h' is the height.

So, the formula for the area A of a trapezoid

$A = \frac{1}{2}(b_{1}+ b_{2})h$

(b) Solve the formula for h

As the formula for the area A of a trapezoid is

$A = \frac{1}{2}(b_{1}+ b_{2})h$

So, formula for height h of trapezoid

$h = \frac{2A}{b_{1}+b_{2}}$

(c) Using the new formula to find the height h of the trapezoid

Using $h = \frac{2A}{b_{1}+b_{2}}$ to find the height h of the trapezoid.

So,

$h = \frac{2A}{b_{1}+b_{2}}$

$h = \frac{2(72)}{16+8}$ ∵b₁ = 16, b₂ = 8, A = 72cm²

$h = \frac{144}{24}$

$h = 6 cm$

So, h = 6 cm

Hence, The height h of the trapezoid will be 6 cm.
