a + b/c when a=16 b=64 c=8

============================================================

Explanation:

The average rate of change is the same as the slope of the line through the endpoints mentioned.

The interval [6, 8] means that we're talking about [tex]6 \le x \le 8[/tex]

So we're tasked to find the slope of the line through (6,1178) and (8,2742)

We'll use the aptly named slope formula.

[tex](x_1,y_1) = (6,1178) \text{ and } (x_2,y_2) = (8,2742)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2742 - 1178}{8 - 6}\\\\m = \frac{1564}{2}\\\\m = 782\\\\[/tex]

The slope through those two endpoints is 782, which is the average rate of change on the interval [6, 8].

------------------

For the interval [5,7] we have [tex]5 \le x \le 7[/tex]

According to the function table,

Like before, use the slope formula to find the slope through (5,690) and (7,1182)

[tex](x_1,y_1) = (5,690) \text{ and } (x_2,y_2) = (7,1182)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1182 - 690}{7 - 5}\\\\m = \frac{492}{2}\\\\m = 246\\\\[/tex]

This is the average rate of change on the interval [5,7].

------------------

The last step is to subtract the slopes:

782 - 246 = 536 which is the final answer

Answer:

Total area = 937.75

Step-by-step explanation:

Area of triangles = ((b*h)/2) * 5

= (12*23/2) * 5

= 138 * 5

Area of triangles = 690

Area of pentagon = a² * √(25 + 10√5) / 4

= 12^2 * √(25 + 10√5) / 4

Area of pentagon = 247.75

Total area = Area of triangles + Area of pentagon

Total area = 937.75

The median is 26

Step-by-step explanation:

A "median" is equivalent to, when the terms are arranged in the proper order, whichever term is in the "middle".

So- first, arrange the terms in ascending order.

[22, 22, 23, 23, 29, 29, 29, 31]

There are an even number- eight- terms in total, so we will take the average of the two "middle" terms.

(29+23)/2; 29 and 23 are the "middle" terms, and there are two of them.

(52)/2 = 26

Therefore, the median is 26.

By setting up the equation 2/5=x/300, we can cross cancel, changing the equation into 5x=600, and by dividing both sides by 5, the 5 in 5x cancels out and 600 divided by 5 is 120.

Answer:

  the dilated coordinates are (12, 9), (6, 9), (12, -6), (6, -6)

Step-by-step explanation:

The dilation factor multiplies each coordinate value when the center is the origin.

__

  (8, 6) ⇒ 1.5(8, 6) = (12, 9)

  (4, 6) ⇒ 1.5(4, 6) = (6, 9)

  (8, -4) ⇒ 1.5(8, -4) = (12, -6)

  (4, -4) ⇒ 1.5(4, -4) = (6, -6)

A quadrilateral is a shape with four vertices

The true statement about the quadrilateral ABCD is that the quadrilateral has unequal lengths

The coordinates of the vertices are given as:

A = (1,1)

B = (5,2)

C =  (8, -6)

D = (0, -8)

Next, we calculate the distance between the vertices using the following distance formula

[tex]d=\sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]AB=\sqrt{(1 -5)^2 + (1 -2)^2} = \sqrt{17}[/tex]

[tex]BC=\sqrt{(5 - 8)^2 + (2 +6)^2} = \sqrt{73}[/tex]

[tex]CD=\sqrt{(8 - 0)^2 + (-6 + 8)^2} = \sqrt{68}[/tex]

[tex]DA=\sqrt{(0 - 1)^2 + (-8 - 1)^2} = \sqrt{82}[/tex]

From the above computation, we have the lengths to be unequal

Hence, the true statement about the quadrilateral ABCD is that it has unequal lengths

Step-by-step explanation:

x = weight of a small box

y = weight of a large box

x + y = 70 pounds

55x + 60y = 4050 pounds

from the first equation we get

x = 70 - y

and we can use that identity in the second equation :

55(70 - y) + 60y = 4050

3,850 - 55y + 60y = 4050

5y = 200

y = 40 pounds

x = 70 - y = 70 - 40 = 30 pounds

so, a small box weighs 30 pounds, and a large box weighs 40 pounds.

Answer:

80cm^2

Explanation:

Okay to do this, it's often better to find the area of each shape separately.

Let's start with the top rectangle:

4cm*7cm = 28cm^2

Bottom rectangle:

to find the length of it, we just add 3cm and 7cm which = 10cm

so:

10cm*4cm = 40cm^2

And finally the triangle:

to find the bottom side: 13cm - 7cm - 3cm = 3cm

to find the height: 4cm + 4cm = 8cm

so:

8cm*3cm*/2 = 24cm/2

= 12cm^2

Now we add them all up:

28 + 40 + 12 = 80cm^2

In the given figure there are two shapes:

First, we have to find the area of Rectangle ABGF & DCGE. After that, area of triangle CHB.

1) Area of Rectangle ABGF:

As, we know:

Formula for Area :-

★ Length × Breadth ★

where,

➝ 4 cm × 10 cm

➝ 40 cm²

Hence, the area of Rectangle ABGF is 40cm².

2) Area of Rectangle DCGE:

As, we know:

Formula for Area :-

★ Length × Breadth ★

where,

➝ 4 cm × 7 cm

➝ 28 cm²

Hence, the area of Rectangle DCGE is 28cm².

3) Area of Triangle CHB:

As, we know:

Formula for Area :-

★ ½ ( base × height ) ★

where,

➝ ½ ( 3cm × 8cm )

➝ ½ ( 24cm )

➝ ½ × 24cm

➝ 12 cm²

Hence the Area of Triangle CHB is 12cm².

Now, Area of Given Shape is:

➝ 40cm² + 28cm² + 12cm²

➝ 52cm² + 28cm²

➝ 80cm²

Thus, the area of the given shape is 80cm².

12÷48=0.25 or 25%. As a result, the percent error is 25%. Hope it helps!

Step-by-step explanation:

The percentage error is 40.9%.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, the estimated value is 52 and the actual value is 88.

The percent error is given

error% = (|estimated - actual|)/actual × 100 %

error% = (|52 - 88|)/88 × 100 %

error% = 40.9%

Hence, the percentage error is 40.9%.
