The percent increase  from last year to this year is 7.94%

From the question, we have the following parameters that can be used in our computation:

Initial height = 63 inches

New height = 68 inches

The percent change from last year to this year is then calculated as

Percent change = (New height - Initial height)/Initial height * 100%

Substitute the known values in the above equation, so, we have the following representation

Percent change = (68 - 63)/63 * 100%

Evaluate

Percent change = 7.94%

Hence, the percentage increase is 7.94%

Rewriting the given trigonometric form using trigonometric identities by eliminating fraction form gives [tex]-cotx.cosx.(sinx+1)[/tex]

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.

There are numerous distinctive trigonometric identities that relate a triangle's side length and angle. Only the right-angle triangle is consistent with the trigonometric identities.

The six trigonometric ratios serve as the foundation for all trigonometric identities. Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to define each of these trigonometric ratios. The six trigonometric ratios are the source of all fundamental trigonometric identities.

We know that,

To find the time and distance at which Liza passes Ralph, we need to solve the system of equations.

Subtracting the first equation from the second, we get:

65x - 60x = y - 25

5x = y - 25

y = 5x + 25

Substituting this value of y into the first equation, we get:

60x + 25 = 5x + 25

55x = 0

x = 0

This means that Liza will pass Ralph 0 hours after she leaves, or at the same time as Ralph. At this time, they will have both traveled 0 miles.

Therefore, the answer is A: Liza will not pass Ralph, because she will never catch up with him.

The annual percentage yield is 4.835%. Mabel Causino has $35,000 to invest in a certificate of deposit for 4 years. The CD earns 4.75% interest compounded daily.

An annual percentage rate, or APR, is a figure that expresses the entire cost of borrowing money as a proportion of the loan's principle. An accurate picture of how much it costs to borrow money is intended to be provided by the APR on a loan or credit card.

Given

Mabel Causino has $35,000 to invest in a certificate of deposit for 4 years. The CD earns 4.75% interest

compounded daily.

1.048353

The table on page A14 shows the cost per $1.00 (over the course of a year).

$35,000×1.048353=$36,692.36

The sum of the initial principle and the amount per $1.00 is the amount (for a year).

$36,692.36−$35,000=$1,692.36

The difference between the amount (for one year) and the initial principal is the interest (for one year).

$1,692.36÷$35,000

=0.04835

=4.835%

The interest (for a year) divided by the initial principle results in the annual percentage yield.

(c)  calculate standard deviation of x:

σ = √σ²

σ = √1.831

σ = 1.3539

The likelihood that the quantity of systems sold will be within one standard deviation of the its mean:

P(μ  - σ < x < μ  + σ ) = P(4.13 - 13539 < x < 4.13 + 1.3539)

                                = P(2.7761 < x < 5.4839)

In terms of b, the perimeter expression is 6 + 4b and the value of b is 9

From the question, we have the following parameters that can be used in our computation:

Dimensions = 8cm and 2b - 5 cm

The above parameters mean that

Length = 8

Width = 2b - 5

The perimeter is calculated as

Perimeter = 2 * (Length + Width)

Substitute the known values in the above equation, so, we have the following representation

Perimeter = 2 * (8 + 2b - 5)

Evaluate the like terms

Perimeter = 2 * (3 + 2b)

Open the brackets

Perimeter = 6 + 4b

Here, we have

Perimeter = 42

This means that

6 + 4b = 42

The proportionality used in the given diagram is 4/3=12/x if ΔABC and ΔDEF are similar. So, option 4 is correct.

Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.

In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle. If and only if all geometry is the Euclidean plane, all triangles are contained in a single plane; however, this is no longer true in higher-dimensional Euclidean spaces. The topic of this article, unless otherwise stated, is triangles in Euclidean geometry, specifically the Euclidean plane.

We have to assume that ΔABC and ΔDEF are similar.

If the triangles are similar,

Then the proportionality is:

AB/BC=DE/EF

4/3=12/x

Therefore, the proportionality used in the given diagram is 4/3=12/x.

The function that models the relationship between plant height (y) and growth time (x) is y = 18 + 5x

The linear equation of two variables

The two-variable linear equation is a solving system for a mathematical problem in which there are two case variables.

In the problem, we get the info that the plant's initial height is 18 cm, meaning this value will not change.

We also get information that the height of the plants increases by 5 cm every month, meaning this value will change over time. If x is the growth time (in months), then the increase in height over time can be written mathematically as 5x.

Based on the two statements above, if y is the plant height (in cm) after x months, then mathematically it can be written as:

y = 18 + 5x

Answer:

y=6

Step-by-step explanation:

The equation of a line in slope-intercept form is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis. In this case, we are given that the line passes through the point (8, 6) and has a slope of 0, so we can plug these values into the equation to find the equation of the line.

Since the slope of the line is 0, the equation of the line becomes:

y = 0x + b

To find the value of b, we need to plug in the coordinates of the point (8, 6) into the equation and solve for b. This gives us:

6 = 0 * 8 + b

b = 6

Therefore, the equation of the line is given by:

y = 0x + 6

This equation tells us that the y-coordinate of any point on the line is always 6, regardless of the x-coordinate of the point. This means that the line is horizontal and passes through the point (8, 6).

Answer:48

Step-by-step explanation:

The linear equation that represents the plant height is the one in the first option:

y = 14 + (3/2)x

We know that the initial height of the plant (this will be the y-intercept of the line) is 14cm, and we also know that the plant grows at a rate of 3/2 cm each day.

So, after x days, the plant is x times 3/2cm plus 14 cm of height, so the linear equation is:

y = 14 + (3/2)x

1.

it is always the same.

the usual equation of a line is

y = ax + b

"a" being the slope, "b" being the y-intercept (the y-value when x = 0).

we see that the y-value is +3 when x = 0. that is "b".

for the slope we pick 2 points (with integer coordinates, if possible).

I see e.g. (0, 3) and (3, 0)

x changes by +3 (from 0 to 3).

y changes by -3 (from 3 to 0).

the slope "a" is -3/+3 = -1

the equation is

y = -x + 3

and again the same

we see that the y-value is -3 when x = 0. that is "b".

I see e.g. (0, -3) and (3, 0) as points.

x changes by +3 (from 0 to 3).

y changes by +3 (from -3 to 0).

the slope "a" is +3/+3 = 1.

Answer:

  500

Step-by-step explanation:

You want to know the rate in 4 years if it is 380 units per day, and increasing by 30 units per day per year.

The rate in 4 years will be the sum of the current rate and the amount of increase. The amount of increase is the rate of increase, multiplied by time:

  amount of increase = (30 units/day)/year × (4 years) = 120 units/day

Then the rate in 4 years will be ...

  new rate = current rate + increase

  new rate = 380 units/day + 120 units/day = 500 units/day

The company will be producing 500 units per day in 4 years.
