Final answer:

The most helpful form to determine the time for the ball to hit the ground is Option A, h(t) = -16(t - 3)(t + 1), as it is already in factored form, making it easy to find the positive root, which represents the time when the ball would hit the ground.

Explanation:

When attempting to determine the time required for the ball to hit the ground in a quadratic model, we are essentially looking for the time when the height of the ball, h(t), is zero. To find this, we need to find the roots of the quadratic equation. Function A, h(t) = -16(t - 3)(t + 1), is already factored, which makes finding the roots straightforward. When dealing with quadratic equations, remember that negative time values do not make sense in this context, so we are only interested in the positive root.

The most helpful form for this task would therefore be Option A, h(t) = -16(t - 3)(t + 1), as the roots can be easily read from the factored form, which directly gives the times when the ball reaches the ground level without further calculation. In this case, the positive root t = 3 seconds represents the time when the ball would hit the ground. Ignoring the root t = -1 because time cannot be negative.

Answer:

h(9) = 62

Step-by-step explanation:

Equate 8x - 10 = 62 and solve for x

8x - 10 = 62 ( add 10 to both sides )

8x = 72 ( divide both sides by 9 )

x = 9

That is h(9) = 62

4^(x- 3) = 18

ln[4^(x- 3)] = ln(18)

ln4(x - 3) = ln(18)

ln4x - ln4(3) = ln18

ln4x = ln18 + 3ln4

x = [ln18 + 3ln4]/ln4

x = 5.0849625007

x is approximately 5.085.

To solve the equation 4^x - 3 = 18, isolate the exponential term, take the logarithm of both sides, apply the power rule, and then divide to solve for x. The solution to the nearest thousandth is x ≈ 2.416.

To solve the equation 4^x - 3 = 18, first add 3 to both sides of the equation to isolate the exponential term:

4^x = 18 + 3

4^x = 21

Now, take the logarithm of both sides. You can use any logarithm base, but it's most common to use either the natural logarithm (ln) or the common logarithm (log base 10). For this example, we'll use the common logarithm.

log(4^x) = log(21)

Using the power rule for logarithms, which states that log(a^b) = b * log(a), you can write:

x * log(4) = log(21)

Now, divide both sides by log(4) to solve for x:

x = log(21) / log(4)

Use a calculator to find the value of x. Be sure to round your answer to the nearest thousandth, as the problem instructs. The answer comes out to:

x ≈ 2.416

This value of x solves the original equation when rounded to the nearest thousandth.

EXPLANATION

The given fractions are:

[tex] \frac{{a}^{3} + {a}^{2} b}{5a} \times \frac{25}{3b + 3a} [/tex]

We factor to obtain:

[tex]\frac{{a}^{2}(a + b)}{5a} \times \frac{25}{3(a + b)} [/tex]

We cancel the common factors to get:

[tex]\frac{{a}(1)}{1} \times \frac{5}{3(1)} [/tex]

We multiply the numerators and also multiply the denominators to get:

[tex] \frac{5a}{3} [/tex]

Answer:

The function has a domain of all real numbers.

The function is a reflection of y =³√x.

Step-by-step explanation:

1. The function is always increasing. - False

(Taking a cube root makes the number smaller so the domain of the function should be decreasing)

2. The function has a domain of all real numbers. - True

The cube root of real number is also real so the minus sign would not result in an imaginary number as it is outside the radical.

3. The function has a range of {y |– ∞ < y < ∞ }. - False

4. The function is a reflection of y =³√x. - True

5. The function passes through the point (3, –27). - False

(these coordinates do not satisfy the function)

The answers are:

[tex]Hypothenuse=28ft+7ft=35ft\\LongerLeg=28ft\\ShorterLeg=28ft-7ft=21ft[/tex]

Since we are working with a right triangle, we can use the Pythagorean Theorem, which states that:

[tex]Hypothenuse^{2}=a^{2}+b^{2}[/tex]

Then, we are given the following information:

Let be "a" the shorter leg and "b" the the longer leg of the right triangle, so:

[tex](7ft+b)^{2}=(b-7)^{2}+b^{2}[/tex]

We can see that we need to perform the notable product, so:

[tex](7ft+b)^{2}=(b-7ft)^{2}+b^{2}\\\\7ft*7ft+2*7ft*b+b^{2}=b^{2}-2*7ft*b+7ft*7ft+b^{2}\\\\49ft^{2} +14ft*b+b^{2}=b^{2}-14ft*b+49ft^{2}+b^{2}\\\\49ft^{2} +14ft*b+b^{2}=-14ft*b+49ft^{2}+2b^{2}\\\\-14ft*b+49ft^{2}+2b^{2}-(49ft^{2} +14ft*b+b^{2})=0\\\\-28ft*b+b^{2}=0\\\\b(-28ft+b)=0[/tex]

We have that the obtained equation will be equal to 0 if: b is equal to 0 or b is equal to 28:

[tex]0(-28+0)=0[/tex]

[tex]28(-28+28)=28(0)=0[/tex]

So, since we are looking for the side of a leg, the result that we need its 28 feet.

Hence, we have that the answers are:

[tex]Hypothenuse=28ft+7ft=35ft\\LongerLeg=28ft\\ShorterLeg=28ft-7ft=21ft[/tex]

Have a nice day!

Answer:

Base = 21 ft

Height = 28 ft

Hypotenuse =  35 ft

Step-by-step explanation:

It is given that,the shorter leg of a right triangle is 7ft shorter than the longer leg. The hypotenuse is 7ft longer than the longer leg

Let longer leg = x then shorter leg  = x - 7 and hypotenuse = x+ 7

To find the side lengths of triangle

Here Base = x-7

Height = x

Hypotenuse = x + 7

By using Pythagorean theorem we can write,

Base² + height² = Hypotenuse²

(x - 7)² + x² = (x + 7)²

x² -14x + 49 + x² = x² +14x + 49

x² - 14x = 14x

x² - 28x = 0

x(x - 28) = 0

x = 0 or x = 28

Therefore the value of x = 28

Base = x - 7 = 21

Height = 28

Hypotenuse = 28 + 7 = 35

Answer:

x < 3

Step-by-step explanation:

Given

x - 5 < - 2 ( add 5 to both sides )

x < 3

Answer:

x < 3

Step-by-step explanation:

The points in inequalities like these is to get x by itself. This being said, since 5 is being subtracted from x, we need to add 5. Whenever you do this, you need to add to both sides. The 5 being added to the -5 will cancel out. -2+5 is 3. Now the equation remains as x < 3

Recall:

For a right triangle where c is the hypotenuse and a and b are the other legs of the right triangle, the Pythagorean Theorem states that: c² = a² + b².

The distance between the two poles = BC + DC

Given:

Apply the Pythagorean Theorem to find BC and DC respectively.

Length of BC:

BC = √(AC² - AB²)

BC = √(15² - 13²)

BC = 7.48 feet

Length of DC:

DC = √(EC² - ED²)

DC = √(10² - 4²)

Final answer:

To find the greatest possible width of the rectangle, set up an equation based on the given information and solve for the width.

Explanation:

The greatest possible value for the width of the rectangle can be calculated by setting up an equation based on the given information.

Let the width be 'w'.

Since the length is three times the width, the length is '3w'.

The perimeter of a rectangle is twice the sum of its length and width. So, 2(3w + w) ≤ 112.

Solving this inequality gives the maximum width as 14 cm.

The vertex is (1,-3)

Step-by-step explanation:

Just look for the numbers that make the inner parts 0. Here, x - 1 is 0 when x = 1 and y + 3 is 0 when y = -3.

Answer:

Step-by-step explanation:

Compare:

(y+3)^2=12(x-1)

(y - k)^2 = 12(x - h)

Here we see that k = -3 and h = 1.  Thus, the vertex of this horiz. parabola is (1, -3).  We know that this parabola is horiz. because it's y or y+3 that is squared, not x or x-1.

Answer:

The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)

Step-by-step explanation:

The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.

Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.

Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).

Remember, a system of equation has a solution when an interception occurs between its equations

Answer:

Step-by-step explanation:

b

Answer:

Step-by-step explanation:

Remember that the solution of a linear system of equations is shown by the interception point between those lines.

In this case, the interception point is at (2,3).

Also, the horizontal line is [tex]y=3[/tex]. Notice that the solution are is below this line, that means the inequality that represents that part is [tex]y\leq 3[/tex].

Now, the other line has y-intercept at -1, that means [tex]b=-1[/tex].

Then, we use two points (0,-1) and (2,3) to find its slope.

[tex]m=\frac{3-(-1)}{2-0}=\frac{4}{2}=2[/tex]

So, the equation that represents that line is [tex]y=2x-1[/tex].

Notice that the area of solution is above this line, that means the inequality is

[tex]y>2x-1[/tex]

Therefore, the sytem that represents the graph is

[tex]y>2x-1\\y\leq 3[/tex]

Notice that we used [tex]\leq[/tex] for the solid line and [tex]>[/tex] for the not solid line.

3rd choice

Step-by-step explanation:

In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.  

The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.

You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)

The error is the 3rd option.

We start with

[tex]\dfrac{4m^{-3}n^{-2}}{m^{-1}n}[/tex]

Simplifying the exponents, we have

[tex]\dfrac{4m^{-3}n^{-2}}{m^{-1}n} = 4m^{-3}n^{-2} (mn^{-1}) = 4m^{-3+1}n^{-2-1}=4m^{-2}n^{-3}[/tex]

So, the exponents are ok.

If we plug the values, we have

[tex]4m^{-2}n^{-3} \mapsto 4(-2)^{-2}(4)^{-3} = 4\cdot \dfrac{1}{(-2)^2}\cdot\dfrac{1}{4^3} = 4\cdot \dfrac{1}{4}\cdot \dfrac{1}{64} = \dfrac{1}{64}[/tex]

The second set of brackets is a little bit tricker. Minus signs are not to be ignored.

(-10r - 25) : -5(2r + 5)

Now put both together,

2r^2(2r + 5) - 5(2r + 5)            

Notice that there is a common factor on either side of that isolated minus sign. The common factor is 2r + 5. Use the distributive property to pull it out.

(2r + 5)(2r^2 - 5)
