someone please help me please please please help me please please please please please please please please please with these quadratic equations​

Step-by-step explanation:

According to the diagram:

The area is:

There are 1680 digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits between them

To determine the number of whole numbers, the following must be true

Case 1: If the sequence starts from the first digit

So, we have:

[tex]Case\ 1 = 3 * 1 * 2 * 1 * 10 * 10[/tex]

[tex]Case\ 1 = 600[/tex]

Case 2: If the sequence starts from the second digit

So, we have:

[tex]Case\ 2 = 9 * 3 * 1 * 2 * 1 * 10[/tex]

[tex]Case\ 2 = 540[/tex]

Case 2: If the sequence starts from the third digit

So, we have:

[tex]Case\ 3 = 9 * 10 * 3 * 1 * 2 * 1[/tex]

[tex]Case\ 3 = 540[/tex]

The total number of whole numbers is:

[tex]Total = 600 + 540 + 540[/tex]

[tex]Total = 1680[/tex]

Hence, there are 1680 6-digit whole numbers that the digits

Answer:

a = 11c - 4

Step-by-step explanation:

7,18,29,40

constant difference = 11

now,

an = a+(n-1)d

or, an = 7+(n-1)11

or, an = 7 + 11n - 11

or, an = 11n - 4

Answer:

25%

Step-by-step explanation:

Let George's salary = $50,000 per year

If his salary dropped by 20%, then his salary would be 80% of his previous salary (as 100% - 20% = 80%).

Convert 80% to a decimal: 80% = 80/100 = 0.8

Therefore, 80% of 50000 = 0.8 x 50000 = $40,000

We wish to increase his salary back to the original amount of $50,000.

The difference between the two salaries is : 50000 - 40000 = 10000

Therefore, we need to calculate the percentage that $10,000 is of $40,000.

⇒ (10000 / 40000) x 100 = 25%

So George's salary needs to increase by 25% to get back to where it was before the salary drop.

Answer:

Yes, they are equivalent expressions, by the Associative Property

Step-by-step explanation:

Both of these expressions are equal to:

4a + 5a + 3c

(and then, 9a + 3c)

This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

Answer:

Tree A equation: y = 2x + 5. Tree B equation: y = 3x + 8.

Step-by-step explanation:

The rate at which the tree's grow each month is m (y=mx + b) and the starting length of the trees is b (y=mx+b). Once you know those values plug them into the equation.

Given :-

To Do :-

Solution :-

Given equation to us is ,

→ y = 3x -1

As we know that , the slope intercept form of the line is ,

→ y = mx + c

where m is the slope and c is the y intercept .On comparing both , we have ,

So the graph will cut the y axis at (0,-1) . And will have a slope of 3 .

When y coordinate is 0 ,

So that ,

→ x - 0 / 0 -(-1) = 3

→ x/0+1 = 3

→ x/1 = 3

→ x = 3

Hence one other point is (3,0 ).

Now we may plot the graph using these two points (3,0) and (0,-1) .

Answer:

Step-by-step explanation:

Answer:

g(x) = 3^x -7

Step-by-step explanation:

In an exponential function like this, the constant at the end of the function represents the vertical shift. This means that the original function is shifted 2 units up. So, 9 units lower than +2 is -7. Thus, the new function, g(x), is g(x)=3^x - 7.
We can prove that g(x) is 9 units lower through y-intercepts. The function f(x) has a y-intercept of 3 and g(x) is -6. Since -6 is 9 lower than 3, we know that there is a 9 unit difference between the functions.

Answer:

The answer should be 236g.

Step-by-step explanation:

If we take the amount of flour used for the cake as 'x,' the flour used to make the scones would be (500-x)×2/3 as 2/3 of the remaining is used for the scones.

We know that 60g more flour is used for the cake.

So,

x-60=(500-x)×2/3

Cross multiply, and brng the 3 to the other side.

3(x-60)=(500-x)2

3x-180=1000-2x

Bring the x-terms to one side and the numbers to one side.

3x+2x=1000+180

5x=1180

Divide both sides by 5 to find x(the amount of flour used to make the cake)

Therefore,

x=236g

The term n is the initial amount that the television is to be sold.

We are told that the television in this case is to be sold at a discount piece. The implication of this is that there is something that has to be removed from the price of the television as it is sold.

We are told that what they are to remove from the price of the television is about $75  and that when this is done, the price of the television would be about $300. Thus n is the original price of the television.

The variable n represents the initial value of the television

From the question, we have the following parameters that can be used in our computation:

Amount off = $75

New price = $300

When represented as the equation, we have

n - 75 = 300

Add 75 to both sides of the equation

So, we have the following representation

n = 375

This means that the initial price of the television is $375

9, 30, 93, 282, 849

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

Explanation:

The first term is 9 because of the notation [tex]a_1 = 9[/tex]

To get the second term, we use the recursive rule given to us which is

[tex]a_n = 3a_{n-1} + 3[/tex]

I recommend using parenthesis to separate things like this

[tex]a_n = 3(a_{n-1}) + 3[/tex]

If n = 2, then,

[tex]a_n = 3(a_{n-1}) + 3\\\\a_2 = 3(a_{2-1}) + 3\\\\a_2 = 3(a_{1}) + 3\\\\a_2 = 3(9) + 3\\\\a_2 = 27 + 3\\\\a_2 = 30[/tex]

The second term is 30.

You can use the same idea as above to find the third term, or you can use this slightly different approach

[tex]\text{third term} = 3*(\text{second term}) + 3\\\\\text{third term} = 3*(30) + 3\\\\\text{third term} = 90 + 3\\\\\text{third term} = 93[/tex]

To generate any new term, we first triple the previous term and then add on 3.

Answer:

13.71% or rounded we have 14%

Step-by-step explanation:

We need to find the area so we need to use the formula of Area = piR^2

>> Area of bulls-eye = π(2.5)^2 = 19.63in^2

>> Area of whole target = π(6.75)^2 = 143.13in^2

NOTE: The target values above are halved values of 5 and 13.5

Now, all we have to do is divide the area of the bullseye by the area of the target, so some simple stuff.

19.63/143.13 > 0.13714804 > In a percent we have 13.71% or rounded we have 14%
