Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1). The polynomial is f(x)=-5(x+4)³(x-3).

Given that,

Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1)

We have to find the polynomial of f(x) which satisfy the conditions.

Here,
We have the zeros of the polynomial are -4 (multiplicity 3), 3(multiplicity 1)

Which we can write as -4,-4,-4,3 are the zeros.

Then we can write the polynomial as

f(x)=ω(x+4)³(x-3)

We have to first find the value of ω.

So,

We have f(0)=960

ω(0+4)³(0-3)=960

ω(4)³(-3)=960

64ω(-3)=960

-192ω=960

ω=960/-192

ω=-5

We got the ω as -5.

The polynomial f(x)=-5(x+4)³(x-3)

Therefore, the polynomial is f(x)=-5(x+4)³(x-3).

The statement that justifies the triangles' similarity is (c) SSS similarity theorem

The triangles are given as

Triangle ABC and Triangle DBE

From the figure, we can see that the corresponding vertical lines of either triangle are parallel (but not equal)

This means that, the triangles are similar triangles

This is so because the other two sides of the smaller triangle lie completely on the bigger triangle

As a general rule, the corresponding sides of similar triangles are in proportions

So, we can say that the corresponding side lengths of the triangles are similar

The statement that justifies this is the Side-Side-Side similarity theorem

Answer:

the ratio is 6.5 : 1.5

Step-by-step explanation:

it asks "what is the ratio of time spent studying in math to studying for English?"

ratio uses the ":" mark. also you put the parts like this:

first part : second part

the parts can be found by looking for the "to" as indicated bold in the question

the first part of the ratio it asks is the "time spent studying in math" in hours which is 6.5

the second part of the ratio it asks is the "time spent studying in English" in hours which is 1.5

so the answer is:

6.5 : 1.5

Answer:

Ratio of time spent studying in math to studying for English

[tex]\large \text{$=\dfrac{13}{3}$ }[/tex]

Step-by-step explanation:

What is a ratio?
We use ratios to compare two numeric quantities or quantities with the same units

Basically a ratio of one quantity x to another quantity y can be expressed in the following ways, all read as the ratio of x to y

x/ y

x to y

x : y

The most useful way of representing a ratio is by using the fractional form because it can be used in determining other quantities

In this problem you spend 6.5 hours/week  studying for math and 1.5 hours/week studying for English

Since both units are the same (hours/week) we can compute the ratio as

[tex]{\dfrac{\text{Number of hours studying math}}{\text{Number of hours studying English}}\\\\= \dfrac{6.5}{1.5}\\\\[/tex]

We can simply this fraction as follows

Multiply both numerator and denominator by 10

[tex]= \dfrac{65}{15}\\\\[/tex]

Divide both sides by 5

[tex]\dfrac{65 \div 5}{15 \div 5}\\\\= \boxed{\bold{\dfrac{13}{3}\\\\}}[/tex]

This is the same as 13:3 or 13 to 3

(Be careful what is the numerator and what is the denominator.
If the question had asked for the ratio of hours studying English to hours studying Math then the ratio would be 1.5/65 = 15/65 = 3/13)

The relation which is a function among the answer choices is; A coordinate grid containing a U shape with arrows on both ends that opens to the right. The bottom portion of the U passes through the origin.

A function is a relation in which each element of the domain is associated with exactly one element of the codomain.

A relation can be tagged a function if it describes that there should be only one output (y - value) for each input ( x - value). Put simply, a function is a kind of relation (defined by a set of ordered pairs) in which case, it ensures that every x-value is associated with only one y-value.

On this note, since the relation described in the first answer choice is such that every x-value is associated with only one y-value as it is a parabola (quadratic function), it is termed a function.

y = -1/5x +1/2 linear function has the same slope .

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. We shall comprehend the slope-finding method and its applications in this essay.

First solve for the slope

Based on the fact that the researchers are 96% confident that they are correct, then the probability that they are actually wrong is 4%.

If we are to believe the assertions of the researchers that they are 96% certain of them being correct, then the probability that they are wrong can be found by the formula:

The slope of the line is [tex]\frac{2}{3}[/tex]

The increase divided by the run is the slope. By examining the rise and run, you can infer the slope of a line from its graph. A line has the property that its slope remains constant throughout.

Determine the coordinates of two points along the line that you choose. Find the difference between these two points' y-coordinates (rise). Find the difference between these two points' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.

The slope of the line is [tex]\frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]

⇒ [tex]\frac{-7-(-5)}{9-6}[/tex]

Dilate figure A with center o and scale factor 2

What is transformation?
The transformation, or f: X → X, is the name given to a function, f, that maps to itself. The pre-image X becomes the picture X following the transformation. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point.
Example: A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.

We know that re-sizing an item uses a transition called dilation.

The equation of the line passing through points (-2, 5) can be written as follows

Equation of a straight line is an equation of the form y = mx + c, where

The slope is the gradient which is the ratio of the difference in the y direction to the difference in x direction.

given that the equation of the line is x + 3y = 7

rewriting the equation gives

y = -x/3 + 7/3

hence the slope is -1/3, and this is equated with the formula for slope

[tex]\frac{y-y_{1} }{x-x_{1} }=-\frac{1}{3}[/tex]

substituting the values for points  (-2,5)  and cross multiplying gives

3 (y - 5) = - ( x - -2)

y - 5 = - (x + 2 ) /3

y - 5 = -x/3 - 2/3

y = -x/3 - 2/3 + 5

y = -x/3 + 13/3

Rewriting the equation of the line in standard form is done as follows

y = -x/3 + 13/3

3y = -x + 13

x + 3y = 13

Answer:

  $1258.09

Step-by-step explanation:

You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.

In order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.

  I = Prt

  150,000 = P(0.08)(1)

  P = 150,000/0.08 = 1,875,000

The value of an ordinary annuity is given by the formula ...

  A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.

Using the values we know, we can find P:

  1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P

  P ≈ 1258.09

You would need to deposit $1258.09 each month.

Additional comment

The formulas used here assume that the deposits and withdrawals occur at the end of the month.

Given that P is a point on the perpendicular bisector, l, of MN, we have proved that PM = PN because By the definition of reflection, point P is the image of itself and point N is the image of N.

We are given :

P is a point on the perpendicular bisector, l, of MN.

Now, we want to prove that PM = PN

A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .

By the definition of reflection, we can deduce that point P is the image of itself , and point N is the image of M .

The line l acts as a Line of symmetry or axis of reflection.

Now, in transformations, we know that reflections preserve length and as a result, PM = PN.

Therefore, we will conclude that point N is the image of M .

Answer:

P(A|B) =  1/2

Step-by-step explanation:

Sample space for B = {10, 20, 30, 40, 50, 60, 70, 80}

where B is even

Total number of elements in sample space = 8

P(A|B) = Probability of a number being 40 or less from the sample space of 8

Sample space for A|B  = {10, 20, 30, 40}

So out of a possible 8 elements in the sample space for B only 4 elements can be chosen for the sample space of A

So P(A|B) = 4/8 = 1/2
