Answer:

y=4(3)^x

Step-by-step explanation:

The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.

Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)

The exponential form of an equation is given by =

y = abˣ

Where, a is the y-intercept,

a = 4 here,

y = 4bˣ

Now substitute 6 for x and 2916 for y,

2916 = 4(b)⁶

b⁶ = 729

b = 3

Therefore,

y = 4(3)ˣ

Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent

Step-by-step explanation:

In the proof to show that the sum of the angles in a triangle = 180°, we have;

For a triangle located between two parallel lines, such that the base of the triangle coincides with one of the parallel lines, we have;

The angle formed by one of the base angles and the adjacent side of the extension = 180° by the sum of angles on a straight line

From the attached diagram of a triangle between two parallel lines, we have;

∠e + ∠b = 180° by the sum of angles on a straight line postulate

∠e = ∠a + ∠d by alternate interior angles postulate

∠c = ∠d by alternate interior angles postulate

∴ ∠e = ∠a + ∠c by substitution property

∴ ∠e + ∠b = ∠a + ∠c + ∠b  = 180° by substitution property

Therefore, the sum of the interior angles of a triangle, ∠a + ∠c + ∠b  = 180°.

Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.

Therefore,

21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

Answer:

Use 12 more pounds of pasta.

Step-by-step explanation:

A restaurant uses 3 pounds of pasta for a party of 14 people. If they are cooking pasta for a party of 56 people, what should they do?

Hence, we have:

14 people = 3 pounds of pasta

56 people = x

Cross Multiply

14 × x = 56 × 3

14x = 56 × 3

x = 56 × 3/14

x = 12 pounds of pasta

Hence, if they are cooking for 56 people they should use 12 pounds of pasta

y =  3x - 4

x = 0,  y = 3*0 - 4

          y = -4

(0 , -4)

x = 1 ,    y = 3*1 - 4

            y = 3 - 4

            y = -1

(1 , -1)

x = 2  , y = 3*2 - 4

           y = 6 - 4

           y = 2

Given:

Number of students = 35

Two out of every five boys in the club are boys.

To find:

The number of students in the club that are boys.

Solution:

Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.

Let the number of boys be 2x and number of students be 5x.

According to the question,

[tex]5x=35[/tex]

[tex]x=7[/tex]

Now, the number of boys is

[tex]2x=2(7)[/tex]

[tex]2x=14[/tex]

Therefore, 14 students in the club are boys.

Step-by-step explanation:

Answer:

x column- 1.25, 7.5, 45.

y column- 5, 30, 180.

Step-by-step explanation:

Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.

Step-by-step explanation:

1000 is the answer man you want it right

Step-by-step explanation:

100 / 2 (1500/5 (6 + (21 + 7 - 24)))

= 100 / 2 (1500/5 (6 + (28 - 24)))

= 100 / 2 (1500/5 (6 + (4)))

= 100 / 2 (1500/5 (10))

= 100 / 2 (300 (10))

= 100 / 2 (3000)

= 50 (3000)

= 150000

Rule: BODMAS (Brackets first so if there's bracket in bracket solve the bracket in the brackets first)

if left + - x /, solve x and / first from left to right then when there's + - left solve everything from left to right
