The question is an illustration of simple interest.

The equation that relates Barry's savings after t years is; \(f(t)=1300 + 28.6t\)

The given parameters are:

\(P = 1300\) --- the amount deposited

\(r = 2.2\%\) --- annual interest

So, the interest is calculated using:

\(I = PRT\)

This gives

\(I = 1300 \times 2.2\% \times t\)

\(I = 28.6 \times t\)

\(I = 28.6t\)

So, the equation that relates Barry's savings after t years is;

\(f(t)=P + I\) --- i.e. the amount deposited plus the interest

This gives

\(f(t)=1300 + 28.6t\)

Hence, the required equation is: \(f(t)=1300 + 28.6t\)

I'm stuck on this question for math in middle school, so I can't help

The number of positive integers which are less than 1992 and  not factorial tails  are 396.

Let for some positive integer with exactly n zeros be m

Number at the end of zeros of m! be f(m)

f(m) = ( m /5 ) + ( m /25 ) + ( m /125 ) + ( m /625 ) + ....

Here 'm' is multiple of 5

So ,f(m) = f( m + 1) = f( m + 2) = f( m + 3 ) = f( m + 4 )

And f(m) ≤ ( m /5 ) + ( m /25 ) + ( m /125 ) + ( m /625 ) +...

              = m / 4.03

              = m / 4

Value of m greater than 7964 such that f(m) = 1991

f( 7975 ) = 1991

Number of distinct positive integer 7975 / 5 = 1595 less than 1992

Number of positive integers less than 1992 and they are not factorial tails  are equal to

= 1991 - 1595

= 396.

Therefore, there are 396 positive integers which are less than 1992 and  are not factorial tails.

Yes, you can show significant differences using superscripts in an ANOVA (Analysis of Variance) single-factor test.

In an ANOVA test, superscripts are commonly used to indicate significant differences between the means of different groups or treatments.

Typically, letters or symbols are assigned as superscripts to denote which groups have significantly different means. These superscripts are usually presented adjacent to the mean values in tables or figures.

The specific superscripts assigned to the means depend on the statistical analysis software or convention being used. Each group or treatment with a different superscript is considered significantly different from groups with different superscripts. On the other hand, groups with the same superscript are not significantly different from each other.

By including superscripts, you can visually highlight and communicate the significant differences between groups or treatments in an ANOVA single-factor test, making it easier to interpret the results and identify which groups have statistically distinct means.

Answer:

283.5 cm squared

Step-by-step explanation:

The surface area of a solid is basically just the sum of the areas of all the exterior sides. In this figure, we have 3 congruent triangles at the top, 3 congruent rectangles on the sides, and 1 triangle at the base. We need to find all these areas.

3 congruent triangles:

The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of one triangle is 10 and the height is 4. So:

A = (1/2) * b * h

A = (1/2) * 10 * 4 = 20

Since there are 3 such triangles, multiply 20 by 3:

20 * 3 = 60 cm squared

3 congruent rectangles:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 6 and the width is 10, so:

A = lw

A = 6 * 10 = 60

There are 3 such rectangles, so multiply 60 by 3:

60 * 3 = 180 cm squared

1 base triangle:

Again we use the formula A = (1/2) * b * h for this area.

Here, the base is 10 and the height is 8.7, so:

A = (1/2) * b * h

A = (1/2) * 10 * 8.7 = 43.5 cm squared

Add all these together:

60 + 180 + 43.5 = 283.5 cm squared

The answer is thus 283.5 cm squared.

Answer:

283.5 cm²

Step-by-step explanation:

3 rectangles + 3 triangles on top + triangular base

3(10×6) + 3(½×10×4) + (½×10×8.7)

180 + 60 × 43.5

283.5 cm²

(f-g)(x) = -x - 14 (option C)

f (x) = 4x - 8

g(x) = 5x + 6

(f-g)(x) means f(x) - g(x)

f(x) - g(x) = 4x - 8 - (5x + 6)

open the parnethesis:

Note: Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.

4x - 8 - (5x + 6) = 4x - 8 - 5x - 6

collect like terms:

f(x) - g(x)= 4x - 5x -8 - 6

f(x) - g(x) = -x - 14

To set up the artificial variable LP (Phase I LP) for the given problem, we introduce an artificial variable, LP, to the objective function with a coefficient of 1. The artificial variable is used to identify infeasible solutions.

To set up the artificial variable LP (Phase I LP), we modify the objective function as follows:

Maximize Z = 4x1 + 7x2 + x3 + LP

The artificial variable LP is introduced to the objective function with a coefficient of 1. This allows us to track its value during the iterations.

The initial constraints remain the same:

2x1 + 3x2 + x3 = 20

3x1 + 4x2 + x3 + x4 = 40

8x1 + 5x2 + 2x3 - x5 = 70

The initial basic variables (BV) are the slack variables corresponding to the equality and inequality constraints, namely, x3 and x4. The artificial variable LP is initially a non-basic variable.

The initial artificial variables' basic variable (BVB) values are set to the right-hand side values of the constraints:

x3 = 20

x4 = 40

The initial artificial variable LP's value is set to 0.

Next, the artificial variable LP is selected as the entering variable, as it has a positive coefficient in the objective function. To determine the leaving variable, we perform the ratio test using the ratios of the right-hand side values and the entering column values (coefficients of LP) for the respective constraints.

The leaving variable is determined based on the minimum ratio, ensuring that the corresponding row represents a valid pivot element. If no valid pivot element is found, the problem is infeasible.

This completes the setup of the artificial variable LP (Phase I LP) without performing a complete pivot. Further steps would involve applying the simplex method and iteratively pivoting to find the optimal solution or identify infeasibility.

Step-by-step explanation:

f(x) = x⁴ + 2

differentiate

f(x) = 4x³ + 0 =0

x(4x²) = 0

at x= 0 f(x) = 0 points = (0,0)

at x= 1. f(x) = 3 points = (4,3)......

The ordered pair is (4,3).

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.

Given:

f(x) = x⁴ + 2

Now, differentiate the above function for the small values

f(x) = 4x³ + 0 =0

x(4x²) = 0

When x= 0

f(x) = 0

So, the points = (0,0)

when x= 1

f(x) = 3

so, the points = (4,3).

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

Let x be the original price of a lawn mower,

If the hardware store is having a 15% off sale on lawn mowers this weekend, the amount discounted is expressed as;

= 15 % of x

= 0.15 of x

= 0.15x

Final sales price = Original price - discounted price;

Final sales price = x - 0.15x

Factor out x;

x - 0.15x = x(1 - 0.15)

Hence the correct equations are (x - 0.15x)  and x(1.00 - 0.15)

The given set of premises can be used to obtain a conclusion using the rule of inference called Modus Tollens. Modus Tollens is a valid argument form that uses the premise of a conditional statement and its negation to reach a valid conclusion. The argument form is as follows:

If P then Q.
Not Q.
Therefore, not P.

Using Modus Tollens, we can write the argument as follows:

If I play hockey, then I am sore the next day.
I did not use the whirlpool.
Therefore, I did not play hockey.

The conclusion obtained from the given set of premises is that the person did not play hockey. This is because the person did not use the whirlpool, which is a condition that follows from being sore after playing hockey. If the person did not use the whirlpool, it means that they were not sore, which implies that they did not play hockey.

In summary, using the rule of inference called Modus Tollens, we can conclude that the person did not play hockey based on the given premises.
