Anybody know the answers to these 3?

Answer:

D

Step-by-step explanation:

D would be the correct answer because the x values have their individual y values. D is the only answer where the x point doesn't repeat, and the only time it can repeat is if the x points have the same y value such as: (2,4) (2,4)

For each value of x, the value of y is different. Then the correct option is D.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

Individual y values exist for each of the x values. The only instance the x point can recur is if the x locations have about the same y value, as in D. (2,4).

Then the points represents a function is (1, 7), (2, 1), (5, 3), (4, 9), (6, 3).

Thus, the correct option is D.

Chuck can afford both the convertible and sports car APEX

Step-by-step explanation:

Answer:

We can say that Chuck can afford both the cars.

Step-by-step explanation:

The EMI formula is :

[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]

p = 28700

r = 6/12/100=0.005

n = 6*12=72

Putting the values in the above formula, we get:

[tex]\frac{28700*0.005*(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

Monthly payment is = $475.67

p = 29200

r = 6/12/100=0.005

n = 6*12=72

Putting the values in the above formula, we get:

[tex]\frac{29200*0.005*(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

Monthly payment is = $483.96

We can see that in both the cases, the monthly payments or EMI's are less than $490.

Therefore, we can say that Chuck can afford both the cars.

Step-by-step explanation:

Answer:less than

Step-by-step explanation:

After multiplying by the LCD, the denominators are eliminated, resulting in the equation (x-2)(x+2) - 3x = (x-2)(x-3). Further simplifying this equation, we obtain x^2 - 3x - 4 = x^2 - 5x + 6 which can then be solved with algebraic methods.

To solve the given equation by multiplying each term by the lowest common denominator (LCD), which is 3x(x-2), we need to eliminate the fractions first.

The given equation is:

(x+2)/(3x) - 1/(x-2) = (x-3)/(3x)

After multiplying each term in the equation by the LCD, we have:

Now, we can write the new equation without denominators:

(x-2)(x+2) - 3x = (x-2)(x-3)

Next, we simplify it:

x^2 + 2x - 2x - 4 - 3x = x^2 - 3x - 2x + 6

x^2 - 3x - 4 = x^2 - 5x + 6

This equation can now be simplified or solved using algebraic methods such as combining like terms or moving all terms to one side in preparation for factoring or applying the quadratic formula.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

First, put this equation in slope intercept form.

[tex]y=mx+b[/tex]

Where m is the slope and b is the y intercept.

[tex]y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3[/tex]

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point [tex](2,1)[/tex] is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.

Answer:

A

Step-by-step explanation:

We can simply treat the inequality like an equation because the numbers are on the line. That is y + 1 = 2(x - 1).

Then, we can plug in some numbers:

If x = 2: y + 1 = 2(2 - 1)

y + 1 = 2

y = 1

So one point on the line is (2, 1). B, C, and D don't work because it is impossible for this point to be on the line; the x coordinate corresponds to another y-coordinate, or vise-versa ((3, 1), (2, 0) and (3, 1), respectively) . Therefore, the correct answer is A.

Answer:

M<FDE = 360 degrees

Step-by-step explanation:

120 degrees is supplementary to x which makes it 120. 120+120=240 degrees. angle x and angle d = 120+120 which makes it 360 degrees.

M<ADE however, is 110+120=280, 360-280=80 degrees which is 110+120+80=360 degrees. So, M<ADE is 360 degrees and it is equal to M<FDE which is also 360 degrees.

All of them are equal. The sum of the figure is 720 Degrees.

Answer:

∠FDE = 130°

Step-by-step explanation:

Since BC and DE are parallel lines, then

∠BDE = ∠ABC = 110° ( corresponding angles are congruent )

The sum of the angles round a point = 360°, thus

∠BDE + ∠BDF + ∠FDE = 360 , hence

110 + 120 + x = 360

230 + x = 360 ( subtract 230 from both sides )

x = 130

Hence x = ∠FDE = 130°

Answer:

3 pallets

Step-by-step explanation:

Divide to find the amount of pallets:

Subtract Exponents to divide

15^13 / 15^5 = 13 - 5 = 8 - 5 = 4 (subtracted 2 times)

You need three to store ALL the water

The stock room will need [tex]15^8[/tex] pallets to store the received [tex]15^13[/tex] water bottles since each pallet can store [tex]15^5[/tex] water bottles and we divide the total number by the pallet capacity.

To calculate the number of pallets needed to store all the water bottles the stock room received, we need to divide the total number of water bottles by the number of bottles a single pallet can hold.

The pallet can store 155 water bottles, and the stock room receives 1513 water bottles. By dividing the total number of bottles by the capacity of a pallet, the calculation is:

1513 ÷ 155 = 1513-5 = 158

Therefore, the stock room will need 158 pallets to store all the received water bottles.

The answer will be $29.02. :)

Answer:

$29.02.

Step-by-step explanation:

We have been given that you save 3 ,260.00 in a savings account earning a 3.55% APR compounded monthly. We are asked to find the total interest earned by the end of the third month.

We will use compound interest formula to solve our given problem.

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,

A = Amount of interest after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of periods interest is compounded per year,

t = Time in years.

[tex]3.55\%=\frac{3.55}{100}=0.0355[/tex]

[tex]\text{3 months}=\frac{3}{12}\text{ year}=\frac{1}{4}\text{ year}[/tex]

Upon substituting our given values in above formula, we will get:

[tex]A=3,260(1+\frac{0.0355}{12})^{12\times \frac{1}{4}}[/tex]

[tex]A=3,260(1+0.002958333)^{3}[/tex]

[tex]A=3,260(1.002958333)^{3}[/tex]

[tex]A=3,260*1.00890128109888[/tex]

[tex]A=3289.0181763823\approx 3289.02[/tex]

Now, we will subtract principal amount from final amount to find amount of interest.

[tex]\text{Amount of interest}=3289.02-3260[/tex]

[tex]\text{Amount of interest}=29.02[/tex]

Therefore, you will earn am amount of $29.02 by the end of the third month.

The exponential form is

[tex] \frac{1}{16} = {4}^{ - 2} [/tex]

EXPLANATION

The given logarithm is

[tex] log_{4}( \frac{1}{16} ) = - 2[/tex]

We want to write the given logarithm in exponential form:

We take the antilogarithm of both sides to obtain:

[tex] {4}^{log_{4}( \frac{1}{16} )} = {4}^{ - 2} [/tex]

We simplify the left hand side to obtain:

[tex] \frac{1}{16} = {4}^{ - 2} [/tex]

Hence the exponential form is

[tex] \frac{1}{16} = {4}^{ - 2} [/tex]

The surface area of Figure 1 is 10.2 square centimeters Less than the surface area of Figure 2.

Step-by-step explanation:

Figure 1

area of a square = s2

=9squared

=81 sq cm

area of triangle = 1/2 bh

=1/2 (9cm) (14cm)

=63 sq. cm

find surface area

SA = 81 sq. cm + 4(63 sq. cm)

SA = 81 sq. cm + 252 sq. cm

SA = 333 sq. cm

Figure 2 Calculation

area of rectangle = lw

a = (12cm) (8 cm)

a = 96 sq. cm

area of triangle = 1/2 bh

=1/2 (8 cm) (6.9 cm)

= 27.6 sq. cm

total surface are of figure 2

SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)

SA = 288 sq. cm + 55.2 sq. cm

SA = 343.2 sq. cm

find the difference between figure 1 and figure 2

343.2 sq. cm - 333 sq. cm = 10.2 sq. cm

Final answer:

We cannot complete the statement definitively about the surface area comparison between the square pyramid and the triangular prism without specific measurements. However, if we knew the dimensions, we could use the principle that surface area scales with the square of the linear dimensions to compare the two.

Explanation:

To complete the statement about the surface areas of Figure 1 (a square pyramid) and Figure 2 (a right triangular prism), we need to consider how areas scale with the dimensions of the shapes. Salviati's example illustrates that surface areas scale with the square of the linear dimensions, which is an important concept in geometry. Applying this concept to two triangles where one is larger than the other with linear dimensions twice as long, the larger triangle will have an area four times greater (area scales with the square of the linear dimensions).

Correct solution #1: Since the larger triangle's sides are twice as long, its area is 22 = 4 times more than the smaller triangle. If we applied similar reasoning and knew the dimensions of Figure 1 and Figure 2, we could compare their surface areas. However, with the provided information, we cannot definitively complete the given statement about the surface area of the pyramid relative to the prism without the specific measurements of each figure.

By understanding that the surface area of shapes scales with the square of their dimensions and using examples like cutting the larger triangle into four smaller ones (correct solution #2), we can tackle the surface area comparison confidently, provided we have the necessary dimensions.

Answer: 26in

s=r*theta

r=s/theta

d=r*2

136ft=r*40pi

r=136/40pi=1.082ft

d=1.082*2=2.1645ft*(12in/1ft)=25.97in

Rounded to nearest in is 26in diameter

The diameter of the bike's tire is calculated by dividing the total distance traveled by the number of revolutions to find the circumference and then dividing the circumference by pi (π) to find the diameter, which is approximately 26 inches.

To find the diameter of the bike’s tire, given that it completes 20 revolutions and travels 136 feet, we can use the relationship between the circumference of a circle (in this case, the tire) and its diameter.

First, we calculate the circumference of the tire by dividing the total distance traveled by the number of revolutions:

Circumference = Total Distance ÷ Number of Revolutions

Total Distance = 136 feet (1 foot = 12 inches, so convert feet to inches for precision)

Total Distance in inches = 136 feet × 12 inches/foot = 1632 inches

Circumference = 1632 inches ÷ 20 = 81.6 inches

Now, we use the circumference to find the diameter:

Circumference = π × Diameter

Diameter = Circumference ÷ π

Diameter ≈ 81.6 inches ÷ π ≈ 26 inches

Therefore, the diameter of the bike’s tire, rounded to the nearest inch, is approximately 26 inches.

Step-by-step explanation:

Length of the right rectangular prism [tex]=7\frac{1}{4}[/tex] inches

Width of the right rectangular prism [tex]=8[/tex] inches

Height of the right rectangular prism [tex]=9[/tex] inches

Then volume of the right rectangular prism = (Length)(Width)(Height)

[tex]=\left(7\frac{1}{4}\right)\left(8\right)\left(9\right)[/tex]

[tex]=\left(7.25\right)\left(8\right)\left(9\right)[/tex]

[tex]=522[/tex] cubic inches

Now volume of the small cubic prism [tex]=(Length)^3=\left(\frac{1}{2}\right)^3=\frac{1}{8}[/tex]

Then number of cubes that can fit into the right rectangular prism [tex]=\frac{522}{\left(\frac{1}{8}\right)}=522*8=4176[/tex]
