I NEED HELP ON THIS ILL GIVE 10 POINTS!

Answer:

A) which graph represents the equation x^2 + y^2 = 2.25?

First, the general equation for a circle can be written as:

(x - a)^2 + (y - b)^2 = R^2

This is a circle of radius R centered in the point (a, b).

Then we can rewrite our equation as:

(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2

Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5

Then we can see that the correct one is graph C.

b) Now we want to solve the system:

x^2 + y^2 = 2.25

y - x = 1

graphically.

To do it we need to graph both equations and see in which points do they intersect.

We already have the first equation graphed, so we only need to also graph the linear equation:

y - x = 1

y = 1 + x

An example of this can be seen in the graph below:

There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

Answer:

5 in.

Step-by-step explanation:

Given that

b1 = 12

b2 = 8

A = 50

Formula is (1/2)h(b1 + b2), on substituting

50 = 1/2 * h(12 + 8)

50 = 1/2 * h(20)

100 = 20h

h = 100/20

h = 5

The height is 5 in

Answer:

A. Line r intersects line p

Step-by-step explanation:

to find the second graph multiply the slope of line p by -10

slope is 1/5 or 0.2

So,

0.2 * -10 = -2

slope of second line is -2

Answer:

40

Step-by-step explanation:

1. Plug in the given value for n

6(5) + (5)2

2. Solve using PEMDAS

(I'm not sure if the 2 after the n is supposed to be squared, but if it was n^2 then the correct answer would be 55, I think)

30 + 10 = 40

Therefore, the answer is 40

Hope this helps :)

Answer:

a = 3, b = 2

[tex]y = 3\cdot 2^x[/tex]

Step-by-step explanation:

[tex]y = ab^x\\3 = ab^0\\12 = ab^2\\~\\3=ab^0=a\cdot 1 = a\\a = 3\\~\\12 = ab^2 = 3b^2\\4 = b^2\\b = 2 \vee b = -2[/tex]

but we know from the graph being defined and positive, that b cannot be -2

b = 2

The value of a is 3 and value of b is 2.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The graph is y=abˣ

The points with coordinates (0, 3) and (2, 12) lie on the graph.

We need to find the values of a and b.

The point (0, 3)

3=ab⁰

a=3

Now point (2, 12)

12=ab²

Now plug in a value as 3

12=3b²

Divide both sides by 3

12/3=b²

4=b²

b=2

Hence, the value of a is 3 and value of b is 2.

Answer:

b

Step-by-step explanation:

Given

12x+ 8 = 10x + 18 ( subtract 10x from both sides )

2x + 8 = 18 ( subtract 8 from both sides )

2x = 10  ( divide both sides by 2 )

x = 5

The equation has one solution

Answer:

B

Step-by-step explanation:

verification

12 x 5 + 8 = 10 x 5 + 18

68= 68

since the answer is 68

it is the only one answer that you can get

Correct question is;

Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)​

Answer:

GCF = 5x² + 8x - 9

Step-by-step explanation:

The given polynomial is;

10x³ + 16x² - 18x

First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.

The greatest number is 2.

Secondly let's inspect the variables to see what we can factor out.

They all contain x. Thus, x is a factor.

Thus, we will divide each term by 2x to obtain the GCF of the polynomial.

GCF = (10x³/2x) + (16x²/2x) - (18x/2x)

GCF = 5x² + 8x - 9

I just did it on EDG, got it wrong so i could give you the answer XD

The likelihood that a randomly chosen consumer on plan B would text on the phone the most frequently is 13/23.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

According to the given data,

Number of customers on plan B = 13 + 10 = 23

Number of customers on plan B who text = 13

P(text|plan B) = P(text and plan B) / P(plan B),

where P(text and plan B) is the probability of a customer being on plan B and texting, and P(plan B) is the probability of a customer being on plan B, can be used to calculate the likelihood that a randomly chosen customer on plan B will text the most.

So,

P(text|plan B) = 13/23

Therefore, the probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23.
