Step-by-step explanation:

zeroes = x intercept.

to find the x intercept we let y or in this case p(x) = 0

Hence,

-9x^2 + 1 = 0

-9x^2 = -1

x^2 = 1/9

x = 1/3

x = -1/3

Answer:

2 : 3

Step-by-step explanation:

if x = 3, y = 2

The difference : x - y = 3 - 2 = 1

represents for "y":

Answer:

A. and C.

Step-by-step explanation:

1. Plug in the values of a, b, and c into the quadratic formula:

[tex]x= \frac{-(-5)+-\sqrt{(-5)^{2}-4(1)(3) } }{2(1)}[/tex]

2. Solve the sqaure root:

[tex]x= \frac{-(-5)+-\sqrt{25-12} }{2(1)} \\\\x =\frac{-(-5)+-\sqrt{13} }{2(1)}[/tex]

3. Simplify the rest:

[tex]x=\frac{5+-\sqrt{13} }{2}[/tex]

4. Separate the solutions:

[tex]x= \frac{5+\sqrt{13} }{2} , x= \frac{5-\sqrt{13} }{2}[/tex]

A and C represent these solutions, therefore they are the anwsers.

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.

Points and their residual values are shown in the table. A 3-column table with 5 rows.

The simple regression line can be represented as,

[tex]\hat y=\alpha +\beta X+\hat e[/tex]

Here α is the constant, β is the slope and e is the residue.

The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.

Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

Answer:

P(blue) ≈ 14.3%

Step-by-step explanation:

probability P is calculated as

P = ( favourable outcome ) ÷ ( total number of possible outcomes )

here favourable outcome is blue of which there are 3

number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21

P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]

to convert to a percentage multiply the fraction by 100%

Using it's concept, it is found that there is a 0.7818 = 78.18% probability that this marble will be a green marble. ​

A probability is given by the number of desired outcomes divided by the number of total outcomes.

There are two ways to end up with a green marble selected.

Hence, the probability that this marble will be a green marble is given by:

[tex]p = \frac{6}{10} \times \frac{9}{11} + \frac{4}{10} \times \frac{8}{11} = \frac{54 + 32}{110} = 0.7818 = 78.18\%[/tex]

Step-by-step explanation:

The equation is 6(2x-1), where X is more than 0. When a shipping company charges $6 to ship a package that weighs up to 1 pound.

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound.

lets make an assumption that the total weight of the shipment is x pound and cost for shipping is y.

the shipping company charges $6 for the first pound.

Up to now, the charge is y=6

After 1 pound, i.e for the remaining (x-1) pounds, they charge $2 per pound.

So, the total charge will be, y=6+2(x-1)

weight is always starting from zero as there is no negative weight.so X>0

so the equation is 6(2x-1), where X is more than 0

Answer:

  (d)  opens the same; wider

Step-by-step explanation:

Multiplying a function by a constant has the effect of vertically scaling the graph of the function by a factor equal to that constant.

__

Here, you're multiplying by 2/3, so each y-value is 2/3 of its previous distance from the x-axis. The effect on the graph of a parabola is to make it "flatter", hence wider in appearance. This does not change the direction in which it opens.

The attachment shows an example.

Answer:

y = (1/4)x + 20

Step-by-step explanation:

The general equation of a line is

y = mx+ b , where m is the slope of the line and b is the y-intercept of the line ( where the line intersects the vertical y-axis)

From the graph we can see that the line intersects the y-axis at 20, so our y- intercept is b = 20

Now will find the slope of the line, and for that we need any two points from the line.

For example let's pick points ( x1= 0, y1 = 20) and ( x2 = 4, y2 = 21)

the slope m = (y2-y1)/(x2-x1) = (21-20)/ (4-0) = 1/4

slope of the line is m = 1/4

The equation of the graph shown in the graph is

y = (1/4)x + 20

The value of n you plug into your equation will be 6. Then the correct option is C.

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

When calculating a loan’s effective rate.

If the interest compounds every two months.

Then the value of n you plug into your equation will be

If the interest is compounded every two months, the interest will be applied six times every year.

Because there are 12 months in a year, the value of n that you will plug into your equation is 6, and it will be compounded every two months.
