Hi there! :)

Answer:

<em><u>C. Third option.</u></em>

<em><u>*The answer must have a positive sign and open inequality.*</u></em>

Step-by-step explanation:

<h2><u><em>Lesson: Graphing Inequalities</em></u></h2>

First, add by 6 from both sides of an equation.

$4d-6+6$

And then simplify.

$4d$

Next, divide by 4 from both sides of an equation.

$\frac{4d}{4}$

And finally, simplify and solve.

$24/4=6$

$24/6=4$

You can also multiply by the numbers.

$6*4=24$

$4*6=24$

Answer: $d$

The arrow must go to the left, and it should be open inequality.

Hope this helps!

Thanks!

Have a great day!

A company is started by four friends. The company was Erica’s idea, so she wants to fill 70% of the orders. Jen, Heather, and To

Pie

The appropriate hypotheses for this test are :

Erica filled 70
Jen filled 10
Heather filled 10
Tonya filled 10

<h3>Meaning of hypothesis</h3>

A hypothesis is a statement that proposes a result that will be tested to get a verified result.A hypothesis is not hundred percent true, that is why it is always put to test. Hypothesis is singular while hypotheses is plural

Making a hypothesis in this case is an attempt to predict an answer or result that will be verified by doing the experiment.

We can conclude by saying that a hypothesis is not hundred percent true.

A parabolic arch has a height of 25 feet and a span of 40 feet. How high is the arch 8 feet from each side of the center?

Llana [10]

Answer:

The correct option is;

21 ft

Step-by-step explanation:

The equation of the parabolic arc is as follows;

y = a(x - h)² + k

Where the height is 25 ft and the span is 40 ft, the coordinates of the vertex (h, k) is then (20, 25)

We therefore have;

y = a(x - 20)² + 25

Whereby the parabola starts from the origin (0, 0), we have;

0 = a(0 - 20)² + 25

0 = 20²a + 25 → 0 = 400·a + 25

∴a = -25/400 = -1/16

The equation of the parabola is therefore;

$y = (-\frac{1}{16})(x-20)^2 + 25$

To find the height 8 ft from the center, where the center is at x = 20 we have 8 ft from center = x = 20 - 8 = 12 or x = 20 + 8 = 28

Therefore, plugging the value of x = 12 or 28 in the equation for the parabola gives;

$y = (-\frac{1}{16})(12-20)^2 + 25 = (-\frac{1}{16})(-8)^2 + 25 = 21 \ ft$ .

For this i would use the equation of a cylinder to find the surface area and the equation would be 2(3.14)1.5(7) + 2(3.14)1.5 = 75.36 and you would want to wrap it in something bigger than the vase itself so the best answer would be 80.11 inches squared
