O D. 130 cm2

9514 1404 393

Answer:

  -3, 7, 8

Step-by-step explanation:

You can fill in the boxes from the table values as shown in the attachment.

The leading coefficient is negative because the parabola opens downward. The value of it is the change in y-value as x changes by 1 unit either side of the vertex.

The vertex is identified by the fact that the y-values are symmetrical either side of the vertex.

Answer:

13 m.

Step-by-step explanation:

Formula for perimeter of a rectangle: side + side + side + side.

In other words, add every side of the rectangle.

[tex]2.5+4+2.5+4=13.[/tex]

Therefore, 13 meters is the perimeter of this shape.

Answer:

13m

Step-by-step explanation:

Perimeter of a Rectangle: 2(L + W) where L is the Length, and W is the Width of the rectangle.

=> 2(4 + 2.5)

=> 2(6.5)

=> 13

Perimeter of the Figure = 13 m

Answer:

from top to bottom: 12, 17, 90

Step-by-step explanation:

the total for the first row is 45, and 2 of the numbers are 23 and 10. so, what you do is add 23 and 10 to get 33. Then you just subtract 33 from 45 to get 12.

Same with the other one. the total is 40 so you just subtract 23 from 40 to get 17.

The last one you add the numbers up. So 40+17+33 is 90.

Answer:

d

Step-by-step explanation:

The ΔDGF and ΔABC can be proven similar through SSS similarity. Therefore, option D is the correct answer.

We need to find which of the given pairs of triangles can be proven similar through SSS similarity.

If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.

Now, form option D.

DF/AB=DG/AC=FG/BC

⇒8/2=10/2.5=11/2.75

⇒4=4=4

Thus, ΔDGF and ΔABC are similar.

Therefore, option D is the correct answer.

Answer:

[tex](d)\ x = 4[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -x^2 + 4x + 12[/tex]

[tex]g(x) = x + 8[/tex]

Required

Find x such that: [tex]f(x) = g(x)[/tex]

This gives:

[tex]-x^2 + 4x + 12 = x+8[/tex]

Collect like terms

[tex]-x^2 + 4x -x + 12 -8=0[/tex]

[tex]-x^2 + 3x +4 =0[/tex]

Expand

[tex]-x^2 + 4x - x+4 =0[/tex]

Factorize

[tex]x(x - 4) - 1(x-4) = 0[/tex]

Factor out x - 1

[tex](x- 1)(x - 4)=0[/tex]

Answer:

50 feet

Step-by-step explanation:

Perimeter is the sum of all of the lengths of the sides.

A triangle has three sides, and three lengths are given, therefore all the sides are given.

The sum of the sides is 20 + 20 + 10 = 50

So the Perimeter is 50 feet

Answer:50

Answer:

The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 9 - 1 = 8

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 3.3554

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 3.3554\frac{2.1}{\sqrt{9}} = 2.35[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 24.3 - 2.35 = 21.95 milligrams

The upper end of the interval is the sample mean added to M. So it is 24.3 + 2.35 = 26.65 milligrams

The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.
