Someone please help with this I’m having a hard time and got it wrong!

Answer:

No solution

Step-by-step explanation:

Given equation is
5a - 10 = 2a -7 + 3a

On  the right side add the a terms together
5a - 10 = 2a + 3a - 7

5a - 10 = 5a - 7

Since we have 5a on both sides, these cancel out giving the absurdity

-10 = -7

This result indicates the equation has no solution

Answer:

x=70

Step-by-step explanation:

Due to the law of alternate interior angles, we can see that one of the angles in the triangle is equal to 35 degrees as well (please see the picture attached).

We're given that one of the exterior angles of the triangle is equal to 105. The exterior angle of a triangle will always be equal to the sum of the two opposite interior angles. Knowing this, we can write:

x+35=105

Subtract both sides by 35

x+35-35=105-35

x=70

Therefore, the value of x is 70 degrees.

Answer:

Step-by-step explanation:

S₄ is the area using Simpson's rule and 4 intervals.

Simpson's rule can be calculated as:

Sᵢ = Δx/3 (f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + ... + 4f(xᵢ₋₂) + 2f(xᵢ₋₁) + f(xᵢ))

Or, Simpson's rule can be calculated as a combination of midpoint and trapezoid sums:

S₂ᵢ = (2Mᵢ + Tᵢ) / 3

Using the first method:

Δx = (4−0)/4 = 1

S₄ = 1/3 (1.00 + 4(1.41) + 2(2.24) + 4(3.16) + 4.12)

S₄ = 1/3 (27.88)

S₄ ≈ 9.29

Using the second method:

S₄ = (2M₂ + T₂) / 3

The midpoint area for 2 intervals is:

M₂ = (2) (1.41) + (2) (3.16) = 9.14

The trapezoid area for 2 intervals is:

T₂ = ½ (1.00 + 2.24) (2) + ½ (2.24 + 4.12) (2) = 9.60

Therefore:

S₄ = (2 (9.14) + 9.60) / 3

S₄ ≈ 9.29

The unit rate of change (slope) from 1996 to 2016 is -.025

What is Ratio?

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. A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, m = y/x, where m is the slope, can be used to express the change in the y coordinate with regard to the change in the x coordinate.

Take notice that tan = y/x.

The given problem is about the decrease of two variables, which represent years and represent video rental.

The ratio here refers to the slope of the linear decreasing behavior, where pairs are (1996,9) and (2016, 4).

The formula for the slope is

\(&m=\frac{y_2-y_1}{x_2-x_1}\)

So, In the given question, we have:

10 video rental locations in 1996;

So,  Assuming a constant decrease in the number of stores:

The slope or the unit rate of change from 1996 to 2016 is:

\(\begin{aligned}&m=\frac{y_2-y_1}{x_2-x_1}=\frac{4-9}{2016-1996}=\frac{-5}{20}=-\frac{1}{4} \\&m=-0.25\end{aligned}\)

So, The Value of the Slope is -0.25

This means that the linear relation decreases, with a constant ratio of 0.25, that is, video rental decreases one per 4-years periods.

The maximum height of the golf ball on Mars is about 48.8 meters.

To find how much longer it would take for the golf ball hit on Mars to reach the ground, we can use the given equation h = -1.9t² + 26t, where h is the height of the object and t is the time in seconds. First, we need to find the time it takes for the golf ball to reach the ground on Mars. Setting h = 0, we get:

0 = -1.9t² + 26t

Solving for t using the quadratic formula, we get t = 13.684 or t = 0.856. Since the golf ball is launched upward, we need the positive value of t, so it takes about 13.7 seconds for the golf ball to reach the ground on Mars. Therefore, it takes 13.7 − 5.4 = 8.3 seconds longer for the golf ball hit on Mars to reach the ground than the golf ball hit on Earth.

To find the maximum height of the golf ball on Mars, we can use the formula h = -1.9t² + 26t, where t is the time when the height is maximum. Since the formula is a quadratic equation, the maximum height occurs at the vertex of the parabola, which is at t = -b/2a.

In this case, a = -1.9 and b = 26, so the time at maximum height is t = -26 / 2(-1.9) = 6.842. Plugging this value into the equation for h, we get:

= -1.9(6.842)² + 26(6.842) ≈ 48.8 meters

Answer:

Tanisha = 14 years

Ana = 7 years

Elicia = 16 years

Step-by-step explanation:

Let T = age of Tanisha

Let A = age of Ana

Let E = age of Elicia

Tanisha is twice as old as Ana:  

T = 2A

⇒ A = (1/2)T

Elicia is 2 years older than Tanisha:

E = 2 + T

Sum of all their ages is 37:

A + E + T = 37

Substitute A = (1/2)T and E = 2 + T into A + E + T = 37 and solve for T:

⇒ (1/2)T + 2 + T + T = 37

⇒ (5/2)T = 35

⇒ T = 14

If T = 14, then

A = (1/2)T = (1/2) 14 = 7

If T = 14, then

E = 2 + T = 2 + 14 = 16

The completed statement on how to graph the ellipse is as follows;

The center of the ellipse is (6, -3). The end points of the major axis are 8 units from the center. The endpoints of the minor axis are 5 units from the center.

To graph the ellipse, connect (-2, -3), (6, 2), (14, -3), and (6, -8) with a smooth curve.

An ellipse is the locus of a point that moves such that the sum of the distance of the point from the two fixed points (the foci of the ellipse) is constant.

The equation of the ellipse in the question is presented as follows;

\(\dfrac{(x - 6)^2}{64} +\dfrac{(y+3)^2}{25} =1\)

The standard form of the equation of an ellipse is \(\dfrac{(x - h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1\)

Where;

(h, k) is the coordinates of the center of the ellipse

a is the length of the semi major axis

b is the length of the semi minor axis

The location of the center of the ellipse in the question is therefore;

(h, k) = (6, -3)

The square of the length of the semi major axis of the ellipse in the question is therefore;

a² = 64

Which gives; a = √(64) = 8

The length of the square of the semi minor axis is b² = 25

Which gives; b = √(25) = 5

The parameters of the ellipse are therefore;

The points on the graph of the ellipse are found as follows;

At point (1, -3), we get;

\(\dfrac{(1 - 6)^2}{64} +\dfrac{(-3+3)^2}{25} \neq1\)

At point (6, 5), we get;

\(\dfrac{(6 - 6)^2}{64} +\dfrac{(5+3)^2}{25} \neq1\)

At point (11, -3), we get;

\(\dfrac{(11 - 6)^2}{64} +\dfrac{(-3+3)^2}{25} \neq1\)

At point (6, -11), we get;

\(\dfrac{(6 - 6)^2}{64} +\dfrac{(-11+3)^2}{25} \neq1\)

\(\dfrac{(-2 - 6)^2}{64} +\dfrac{(-3+3)^2}{25} =1\)

\(\dfrac{(6 - 6)^2}{64} +\dfrac{(2+3)^2}{25} =1\)

\(\dfrac{(14 - 6)^2}{64} +\dfrac{(-3+3)^2}{25} =1\)

\(\dfrac{(6 - 6)^2}{64} +\dfrac{(-8+3)^2}{25} = 1\)

Answer:

Step-by-step explanation:

Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.

From the diagram, it appears as if \(\overline{XZ} \perp \overline{XY}\). To determine if this is the case, we can find the slopes of both segments.

\(m_{\overline{XZ}}=\frac{4-1}{4-1}=1\\m_{\overline{XY}}=\frac{-1-1}{3-1}=-1\)

Since these slopes are negative reciprocals, we know that they are perpendicular.

This means we can use the formula \(A=\frac{1}{2}bh\), where b is the base (XY) and h is the height (XZ).

Using the distance formula,

\(XY=\sqrt{(3-1)^{2}+(-1-1)^{2}}=2\sqrt{2}\\XZ=\sqrt{(4-1)^{2}+(4-1)^{2}}=3\sqrt{2}\)

This means the area is \(\frac{1}{2}(2\sqrt{2})(3\sqrt{2})=\boxed{6}\)

Hey there!

I THINK the answer is 43.75, but im not entirely sure, im not that good at math

The total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.

To calculate the total value of the annuity in 16 years, we can use the formula for the future value of an annuity:

FV = P * ((1 + r)^n - 1) / r

Where:

FV is the future value of the annuity,

P is the yearly payment,

r is the interest rate per compounding period, and

n is the number of compounding periods.

In this case, the yearly payment (P) is $693, the interest rate (r) is 5.3% or 0.053, and the number of compounding periods (n) is 16.

Let's substitute these values into the formula and calculate the total value of the annuity:

FV = 693 * ((1 + 0.053)^16 - 1) / 0.053

FV = 693 * (1.053^16 - 1) / 0.053

Using a calculator, we can evaluate the expression inside the parentheses:

1.053^16 ≈ 1.9738

Substituting this value back into the formula:

FV = 693 * (1.9738 - 1) / 0.053

FV = 693 * 0.9738 / 0.053

FV ≈ 12739.62

Therefore, the total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.

The length of the fence around the enclosure not including the gates is:2l + 2w + 8 m

To find the length of the fence around the enclosure, we need to first find the perimeter of the rectangle and then subtract the combined length of the two gates from it.

Let's assume the length of the rectangle is 'l' and the width is 'w'.

From the given data, we know that each gate is 4 m wide.

Therefore, the width of the rectangle is:

Width = w + (4 m + 4 m) = w + 8 m

The perimeter of the rectangle is:

P = 2l + 2(w + 8 m) = 2l + 2w + 16 m

Now, we need to subtract the combined length of the two gates from the perimeter:

P - 2 × 4 m = 2l + 2w + 16 m - 8 m = 2l + 2w + 8 m

So, the length of the fence around the enclosure not including the gates is:2l + 2w + 8 m
