Step-by-step explanation:

rule for line c: y=x+3

x  y

0  3

1  4

2  5

3   6

I was able to determine the rule because line c has a slope (m) of 1 (it goes up one and sideways one each time). Its y int. is at 3, so that means 3 is b in the equation y= mx+b

Rule for line D: y=1/2x

x y

0 0

2 1

4 2

6 3

Line d is y=1/2x becaise it goes up 1 and then sidewys 2, so slope (m)= 1/2. There is no b becase it crosses the origin.

(-2,-1) (-4,-2) (-6, -3) just extend the line with a ruler.

hope this helps! :)

Answer:

Yes,it is

Step-by-step explanation:

The correct answer should be A.

First consider that 2357/1180 is around 2. So the first part must have the answer of times 2. Then decide how many zeroes must be added. By simple math if you do 118,000,000,000 * 20 (which is ) then you get 2,360,000,000,000. which is roughly the correct number.

The correct answer should be A.

First, consider that 2357/1180 is around 2.

Estimation is the process of finding the number which is close enough to the exact solution. But it is not an exact answer.

So the first part must have the answer of times 2.

Then decide how many zeroes must be added. By simple math if you do 118,000,000,000 * 20.

Then you get 2,360,000,000,000.

which is roughly the correct number.

The whole numbers between 3.75 and 6 is 4 and 5

Answer:

1.22 s

Step-by-step explanation:

h = -810t² + 1980t

This is the equation of a parabola.

We must solve the equation to find the maximum height (h).

The coefficient of x² is negative, so the parabola opens downward, and the vertex is a maximum.

One way to solve this problem is to convert the equation to the vertex form.

We do that by completing the square.

Calculation:

h = -810t² + 1980t

Divide both sides by -810 to make the coefficient of  t² equal to 1.

(-1/810)h = t² - (22/9)t

Square half the coefficient of t

(-11/9)² = 121/81

Add and subtract it on the right-hand side

(-1/810)h = t² - (22/9)t  + 121/81 - 121/81  

Write the first three terms as the square of a binomial

(-1/810)h = (t - ¹¹/₉)² -121/81

Multiply both sides by -810

h = -810(t - ¹¹/₉)² + 1210

You have converted your equation to the vertex form of a parabola:

y = a(t - h)² + k = 0,

where (h, k) is the vertex.

h = ¹¹/₉ and k = 1210, so the vertex is at (¹¹/₉, 2100).

The maximum height of the rocket is 2100 cm.

After ¹¹/₉ s ≈ 1.22 s, the rocket will have reached a height of 1210 cm.

The graph below shows the rocket reaching 1210 cm at 1.22 s.

Step-by-step explanation:

triangle= 1/2bh

rectangle or square = bh

so 1/2(4)3=6

6 times 3= 18

1/2(4)3= 6

4 times 6 = 24

5 times 6 = 30

now you add them all up

6 + 18 + 6+ 24+ 30 =

The Surface area of this wedge is 84 square ft.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area.

To find the Surface are we will find the area of each part individually.

We have two triangle and 3 rectangles.

So, area of Triangle

= 1/2 b h

= 1/2 x 4 x3

= 6 square ft

Area of rectangle

= l w

= 6 x 3

= 18 square ft

Area of 2 rectangle

= l w

= 4  x 6

= 24 square ft

and, area of 3rd rectangle

= 5 x 6

= 30 square ft

So, the Surface area of Figure is

= 6 + 18 + 6 + 24 + 30

= 84 square ft

Answer:

$4.20

Step-by-step explanation:

you first do 1.75 divided by 5 which gives you .35

so you do .35 times 12 which gives you 4.2

The price of a 12-minute phone call is  $4.2.

We have given that,

The price of a 5-minute phone call is $1.75.

We have to determine, the price of a 12-minute phone call.

A price is the (usually not negative) quantity of payment or compensation given by one party to another in return for goods or services.

We first 1.75 divided by 5 which gives you .35

That is,

[tex]\frac{1.75}{5} =0.35[/tex]

[tex](0.35)( 4)=4.2[/tex]

0 .35 times 12 which gives  $4.2.

Answer:

10/3

Step-by-step explanation:

Answer:

You can use the Law of Sines for this problem, but what makes it tough at first glance is that they put a step in before you can use it directly. That first step is to get m∠C. When solving a triangle, always get the third angle if you know the other two so that you can use the Law of Sines (or Law of Cosines) more directly.

The sum of the angles of any triangles is 180°. We know the measures of the two other angles. So we subtract them from 180° to find that third angle.

180° - 76° - 66° = 38°

Now we can use the proportion from the picture. Angle B measures 76°, side b is our unknown, Angle C measures 38°, and side c measures 3 units.

sin 76° sin 38°

----------- = -----------

b 3

Cross multiply to find b (the side). We carry out five places in these calculations to get more accuracy.

3 * sin 76° = b * sin 38°

b = 3 * sin 76° 3 * 0.56611 1.69832

--------------- = --------------- = ---------------- = 5.73044

sin 38° 0.29636 0.29636

To the nearest tenth, b - 5.7 units.

Answer:

8 inches

Step-by-step explanation:

ROCK is a kite. The area of a kite is denoted by:

A = (1/2) * d1 * d2, where d1 and d2 are the diagonals

Here, the two diagonals are x and 15, and we know the area is 60, so plug these into the equation:

A = (1/2) * d1 * d2

A = (1/2) * 15 * x

60 = (1/2) * 15 * x

x = 120 / 15 = 8

Thus, x = 8 inches.

Answer:

the top of the ladder is at 24 feet from the ground

Step-by-step explanation:

Use the Pythagorean theorem to solve for the unknown, since we notice that the ladder is the hypotenuse of a right angle triangle formed by the horizontal distance from the wall to the base of the ladder, and the height of the top of the ladder against the wall. We need to find one of the triangle's sides given its hypotenuse and the other side, so we use the formula:

[tex]side_2=\sqrt{hyp^2-side_1^2}\\ side_2=\sqrt{26^2-10^2} \\side_2=\sqrt{676-100} \\side_2=\sqrt{576} \\side_2=24\,\,ft[/tex]
