It takes 1 second  for the ball to reach its highest point.

Acceleration of gravity is the acceleration by which earth pulls

objects towards itself. Acceleration is the rate of change of speed.

Given,

The initial velocity of the ball = 16 feet/second

The initial height of the ball = 10 feet

The ball will first travel upward with an initial velocity of 16 feet/second

and the ball will reach a height of x feet from the point of release. After

that the ball will travel a total downward distance of (10+16) = 26 feet.

At highest point, velocity=0.

Applying, v = u + at

                0 = 16 + (-16)t

                t = 16/16

                t = 1 second

Hence, the ball will take 1 second to reach the highest point.

The polygons from the figure given below that are similar are Polygon B and Polygon C .

In the question ,

it is given that there are three polygons ,

we have to check which polygons are similar ,

to find the similarity we compare the length of all the polygons .

Let us first check for  Polygon A and Polygon B ,

105/120 = 7/8

80/90 = 8/9.

and  105/120 ≠ 80/90 ,

So , Sides are not in proportion for Polygons A and B.

Hence , the Polygons A and B are not Similar.

Let us check for Polygon A and C .

105/100 = 21/20

80/75 = 16/15.

and 105/100 ≠ 80/75

So , sides are not in proportion for Polygons A and C.

Hence , the Polygons A and C are Non Similar.

Now  for Polygon B and C .

120/100 = 6/5.

90/75 = 6/5.

and  120/100 = 90/75 = 6/5

So , Sides are in proportion for Polygons B and C .

Hence , the Polygons B and Polygon C are Similar.

The APR for this loan is equal to 468%.

In Mathematics, APR is an abbreviation for annual percentage rate and it can be defined as a measure of an amount of money based on a yearly rate of interest, which a borrower must pay on a loan or credit card.

Mathematically, the annual percentage rate (APR) of a loan can be calculated by using this formula:

APR = [((simple interest/principal)/n) × 365] × 100

Where:

n represents the number of days.

Note: n is equal to 14 days (2 weeks).

Next, we would determine the FC for this loan as follows;

FC = $295 - $250

FC = $45.

For the two-week period, we have;

Interest = 45/250

Interest = 0.18.

Therefore, the annual percentage rate (APR) of this loan is given by;

APR = 0.18 × 52/2

APR = 468%.

Answer:

The Answer is 6.

Step-by-step explanation:

12x = 72

12 x 6 = 72

X = 6 because 6 can go into 72 12 times

Answer:

x = 6

Step-by-step explanation:

following the working through

substitute y = - x + 2 into the other equation

5x - 7y = 58

5x - 7(- x + 2) = 58 ← distribute parenthesis by - 7

5x + 7x - 14 = 58

12x - 14 = 58 ( add 14 to both sides )

12x = 72 ( divide both sides by 12 )

x = [tex]\frac{72}{12}[/tex] = 6

substitute x = 6 into y = - x + 2

y = - 6 + 2 = - 4

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, etc.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" symbol in it.

Answer:

  3 solutions

Step-by-step explanation:

You want to know the number of solutions (zeros) of the cubic function ...

  f(x) = -x³ -32x² +12x +40

Any 3rd-degree polynomial function has 3 zeros. (This is the fundamental theorem of algebra.)

Descartes' rule of signs says the one sign change in the coefficients (--++) means there is one positive real root. On its face, this means there will be 0 or 2 negative real roots.

The value of f(0) is positive (40), and the value of f(-1) is negative (-3), so there must be two negative real roots. (F(x) is positive for very large negative x, so there must be two x-intercepts for x < 0.)

A graph shows the roots to be irrational. The three real roots are approximately ...

__

Additional comment

The "steps" are to find the degree of the polynomial. It is 3, so there are 3 zeros. It is not complicated.

What is more complicated is finding their values. The checks we described above can tell whether there are 1 or 3 real roots. (An odd-degree polynomial always has at least 1 real root.) A graph is helpful for finding whether the roots are real or complex, rational or irrational.

Here, any rational roots must be integer divisors of the constant term, 40. We know the root between 0 and -1 is irrational, so all of them are.

The above root values were obtained by Newton's Method iteration, starting from the approximate values shown on the graph.

Answer:

black and white striped bass

Answer: No, they are not inverses of one another.

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

Explanation:

There are at least 3 methods we can use to prove the functions aren't inverses of each other.

------------------------------------

Method 1

Let's say we plugged x = 0 into f(x).

[tex]f(\text{x}) = 2\text{x}+1\\\\f(0) = 2*0+1\\\\f(0) = 1\\\\[/tex]

The input x = 0 leads to the output y = 1.

Then let's treat y = 1 as the input of the g(x) function, so we'll plug x = 1 into here.

[tex]g(\text{x}) = -2\text{x}-1\\\\g(1) = -2*1-1\\\\g(1) = -3\\\\[/tex]

If g(x) was the inverse of f(x), then the g(1) output value should be 0 to get us back where we started. However, we get an output of -3 instead.

This is sufficient evidence to conclude that f(x) and g(x) are not inverses of each other. We only need one counter-example to disprove this claim.

------------------------------------

Method 2

Recall that if f(x) and g(x) are inverses of each other, then we have the following two properties

The left hand side of each equation involves the concept of "function composition".

Let's see what f(g(x)) is equal to in this case.

[tex]f(\text{x}) = 2\text{x}+1\\\\f(g(\text{x})) = 2(g(\text{x}))+1\\\\f(g(\text{x})) = 2(-2\text{x}-1)+1\\\\f(g(\text{x})) = -4\text{x}-2+1\\\\f(g(\text{x})) = -4\text{x}-1\\\\[/tex]

We do not get an output of simply x only, so this is another way to see how we don't have inverses.

Through similar steps, you should find that [tex]g(f(\text{x})) = -4\text{x}-3[/tex] which is further confirmation that f(x) and g(x) are not inverses of each other.

------------------------------------

Method 3

Let's ignore g(x) for now. We'll start with f(x) and find the inverse of it.

The process involves this basic outline:

So,

[tex]f(\text{x}) = 2\text{x}+1\\\\\text{y} = 2\text{x}+1\\\\\text{x} = 2\text{y}+1\\\\\text{x}-1 = 2\text{y}\\\\\text{y} = \frac{\text{x}-1}{2}\\\\f^{-1}(x) = \frac{\text{x}-1}{2}\\\\[/tex]

Unfortunately we do not end up with -2x-1 as the actual inverse.

So if [tex]g(\text{x}) = \frac{\text{x}-1}{2}[/tex] was the case, then f(x) and g(x) would be inverses of each other.

Through similar steps, the inverse of [tex]g(\text{x}) = -2\text{x}-1\\\\[/tex] is [tex]g^{-1}(\text{x}) = -\frac{\text{x}+1}{2}\\\\[/tex]

For the given right triangle the measure of the remaining angles are 2.9° and 87.1° and the remaining sides are 5.9 cm and 116.85 cm respectively.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

Given that,

In a right triangle tan(P) = 0.051

And, hypotenuse = 117 cm.

The given data can be shown in the diagram as follows,

From the diagram it can be written as,

tan(P) = 0.051

=> P = 2.9°

Then, ∠Q = 180° - (90° + 2.9°)

                = 87.1°

Now, Sin(P) = p/117

        => Sin(2.9°) = p/117

        => p = 117 × Sin(2.9°)

                = 5.9

Similarly, Cos(P) = q/117

            => Cos(2.9°) = q/117

             => q = 117 × Cos(2.9°)

                      = 116.85

Hence, the measure of the remaining angles are 2.9° and 87.1° and the remaining sides are 5.9 cm and 116.85 cm respectively.
