If you have a cubic polynomial of the form y = ax^3 + bx^2 + cx + d and lets say it passes through the points (2,28), (-1, -5), (4, 220), and (-2, -20) what would the coefficients a, b, c, and d equal? So confused, I'd greatly appreciate help! Thank you!

Answer:

fractions

Step-by-step explanation:

Answer:

A number or ratio expressed as a fraction of 100

Step-by-step explanation:

Use outside of percentages but reused under 100 when explained.

Steepness of a hill or gradient of a line =   rise/run x 100

On a graph the numbers go from 0 for flat, to 100% at 45 degrees, to infinity as it approaches vertical.

Percentage is Tangent of a circle as where it meets it angle it always is intercepted by the circumference or new angle and becomes less than 180 as it forms a leg of a shape, or a side and 1% represents 100 x 0.01000033334% in Radians as another example. we multiply by 100 and get 1 Rad or a 180 degree line.  Broadness of usefulness in percentage is the ratio so 1% of a radian can be the decimal above, and 100% of 1 rad = 180/pi =57.2957 We find a semi-circle has an arc length of pi*r and also that it is 180 degrees. From that you can conclude that the number of degrees in a radian is 180/pi and shows 50% of the circle but 100% of 1 radian.

Consider the triangle ABD,

Here,

AB = 5

BD = 15

AD = s

As we know,

In a triangle, the sum of lengths of two sides is greater than the third side.

So,

[tex]5 + 15 > s[/tex]

[tex]15 + s > 5[/tex]

[tex]s + 5 > 15[/tex]

Now,

To satisfy the equation, the value of s can possibly be 11, 12, 13, 14, 15, 16, 17, 18, 19

Answer: the value of s is 17 units

Step-by-step explanation: 14% of the mothers work part-time in families where the father works part-time while 7% of the mothers work part-time in families where the father is not working.

Probabilities are used to determine how likely or unlikely an event is. From the 2-column table, it is twice as likely to get a family where the father and the mother work part-time than a family where the father doesn't work, and the mother works part-time.

We use the following representation:

[tex]FF \to[/tex] Father works full-time

[tex]FP \to[/tex] Father works part-time

[tex]FW \to[/tex] Father not working

[tex]MF \to[/tex] Mother works full-time

[tex]MP \to[/tex] Mother works part-time

[tex]MW \to[/tex] Mother not working

Next, we test each of the 4 options, till one of the options is true (see attachment)

Choice A:

The claim in choice A is that:

[tex]P(FP\ and\ MP) = 2 \times P(FW\ and\ MP)[/tex]

From the given table, we have:

[tex]P(FP\ and\ MP) = 0.14[/tex] ---- father works part-time and mother works part-time

[tex]P(FW\ and\ MP) =0.07[/tex] ---- father not working and mother works part-time

Put the above values in the following equation

[tex]P(FP\ and\ MP) = 2 \times P(FW\ and\ MP)[/tex]

[tex]0.14 = 2 \times 0.07[/tex]

[tex]0.14 = 0.14[/tex]

The above equation is true.

Hence, choice (A) is true

Answer:

1x+ 1y =11

10x + 5y = 80

x = the cost of a taco = $5

y = the cost of a burrito = $6

Step-by-step explanation:

x = the cost of a taco

y = the cost of a burrito

1x+ 1y =11

10x + 5y = 80

rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:

10x + 5( 11-x) = 80 distribute left side

10x + 55 - 5x = 80 combine like terms

10x - 5x = 5x

5x + 55 = 80 subtract 55 from both sides

5x = 80 - 55

5x = 25 divide by 5

x = 5

plug in for y in 1st equation y = 11--x =11-5 = 6

Step-by-step explanation:

Answer:

91.92%

Step-by-step explanation:

Given that:

Mean (μ) = 6.2, standard deviation (σ) = 1.5

Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3

For x = 8.3, the z score is:

[tex]z=\frac{x-\mu}{\sigma}=\frac{8.3-6.2}{1.5} =1.4[/tex]

From the probability distribution table:

P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%

Answer:

f(-2)=15

Step-by-step explanation:

To find f(-2), we want to find what f(x), or y is, when x is equal to -2.

f(x)= -5x+5

Therefore, we can substitute -2 in for x.

f(-2)= -5(-2)+5

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Multiply -5 and -2

f(-2)=10+5

Add 10 and 5

f(-2)=15

Answer:

f(-2) = 15, or y = 15

Step-by-step explanation:

f(-2) = -5(-2) + 5

f(-2) = 10 + 5, a negative multiplied by a negative will be a positive !

f(-2) = 15

y = 15

Answer:

Eric

Step-by-step explanation:

First, we determine the distance of each player to the hole using the distance formula.

Given points [tex](x_1,y_1)$ and (x_2,y_2)[/tex]

Distance[tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Eric

The hole is at (3,2)

Eric's golf ball is at point (-6,6)

Distance=[tex]\sqrt{(-6-3)^2+(6-2)^2}[/tex]

[tex]=\sqrt{(-9)^2+(4)^2}\\=\sqrt{97} \\\approx 9.85[/tex]

Cam

The hole is at (3,2)

Cam's golf ball is at point (8,-6)

Distance=[tex]\sqrt{(8-3)^2+(-6-2)^2}[/tex]

[tex]=\sqrt{(5)^2+(-8)^2}\\=\sqrt{89} \approx9.43[/tex]

Brooke

The hole is at (3,2)

Brooke's golf ball is at point (10,8)

[tex]Distance=\sqrt{(10-3)^2+(8-2)^2}\\=\sqrt{(7)^2+(6)^2}\\=\sqrt{85} \approx 9.22[/tex]

Since Eric's ball is the farthest from the hole, Eric should shoot next.

C is (-18, 24)

Scale factor --> 1 1/3

A is (9, - 4 1/2)  *4 1/2 is also 4.5

Brainliest please, I need a few more :D

The true statement are; The coordinates of C prime are (–18, 24). The scale factor is 1 1/3 . The coordinates of A are (9, –4.5).

Dilation of a figure will leave its sides get scaled (multiplied) by same number.

Thus, suppose if a rectangle is dilated, and its sides were of length = L and width = W, then its dilated version would be having length = Ln, and width = Wn where n is the factor of scaling.

At image B (-24, -12) and pre image B (-18, -9),

we can work out the scale factor by (-24/-18) and (-12/-9) both equal 4/3

Using the scale factor to go from the pre image to the image,

We can find C coordinate by pre image C by the scale factor.

C is (-13.5 x 4/3) and (18 x 4/3)

C is (-18, 24)

So, The scale factor is 4/3, which is the mixed numeral of 1 1/3.

To find the pre image of point A;

A is (12/(4/3)) and (-6/(4/3))

A is (9, - 4 1/2)

Hence, the true statement are;

The coordinates of C prime are (–18, 24).

The scale factor is 1 1/3 .

The coordinates of A are (9, –4.5).
