Answer:

C

Step-by-step explanation:

To evaluate (f ￮ g)(x)

Substitute x = g(x) into f(x)

f(x² + 14) = x² + 14 - 14 = x² → C

The value of (fog)(x) = x^2. So, option C is correct.

The functions f(x) and g(x) are composite functions then,

(fog)(x) = f(g(x)).

Given that,

f(x) = x - 14

g(x) = [tex]x^2+14[/tex]

Then,

(fog)(x) = f(g(x))

           = ([tex]x^2+14[/tex]) - 14

           = x² + 14 - 14

           = x²

Therefore, the value of (fog)(x) = x².

Answer:

Option D is correct.

Step-by-step explanation:

The length of 2 sides of triangle are given i.e 10 cm and 16 cm.

We need to find the range of the values of length of the third side.

Sum of 2 sides of triangle is greater than the 3rd side

so, 10+16 = 26

So, the length of third side should be less than 26

and we know that the length of third side should be greater than the absolute difference of other two sides

16-10 = 6

So, the length of third side should be greater than 6

Combining both we get 6<x<26

Hence Option D is correct.

The range of possible values for the third side of the triangle is 6 < x < 26

10 + 16 = 26 cm

Difference = 16 cm - 10cm

= 6 cm

Therefore, the range of value of the third side is x is greater than 6cm less than 26cm

6 < x < 26

GCF=4

EXPLANATION

The given monomials are:

[tex]8m = {2}^{3} m[/tex]

[tex]36 {m}^{3} = {2}^{2} \times {3}^{2} {m}^{3} [/tex]

[tex]12 = {2}^{2} \times 3[/tex]

The greatest common factor is the product of all the least powers of the common factors.

We can see that:

[tex] {2}^{2} [/tex]

is the common to all the factors.

Therefore the greatest common factor is

[tex] {2}^{2} = 4[/tex]

Answer: [tex]GCF=4[/tex]

Step-by-step explanation:

To find the Greatest Common Factor (GCF) of 8m, 36m³, and 12, you need to descompose them into their prime factors. Then:

[tex]8m=2*2*2*m=2^3*m\\\\36m^3=2*2*3*3*m^3=2^2*3^2*m^3\\\\12=2*2*3=2^2*3[/tex]

You can observe that the common factor with the lowest exponent is the following:

[tex]2^2[/tex]

Therefore,  the Greatest Common Factor (GCF) of 8m, 36m³, and 12 is:

[tex]GCF=2^2\\GCF=4[/tex]

C = 50.24 inches

Final answer:

Maggie needs to practice at least 1.5 hours on each of the two remaining days.

Explanation:

To determine the minimum number of hours Maggie needs to practice on each of the two remaining days, we can set up an inequality based on the given information. Maggie needs to spend at least six hours each week practicing the piano, and she has already practiced three hours. Let's let x represent the number of hours she needs to practice on each of the remaining two days. The inequality can be written as:

3 + 2x ≥ 6

Solving for x, we subtract 3 from both sides of the inequality:

2x ≥ 3

Then, we divide both sides by 2 to solve for x:

x ≥ 1.5

Therefore, Maggie needs to practice at least 1.5 hours on each of the two remaining days.

Maggie must practice for at least [tex]$\dfrac{3}{2}$[/tex] hours each of the last two days.

Let x equal the number of hours Maggie practices each of the last two days. Since she Needs to practice at least 6 hours per week, and she already practiced 3 hours this week, she must practice for at least 6 - 3 = 3 more hours.

Splitting this time evenly between the two days means she practices x hours each day.

This can be expressed in the following inequality: [tex]$x + x \geq 3$[/tex] which combines the information about the minimum number of hours needed and the fact that she splits the remaining time evenly.

Simplifying the left side of the inequality gives [tex]$2x \geq 3$[/tex]. Dividing both sides by 2 gives [tex]$x \geq \dfrac{3}{2}$[/tex].

Thus, Maggie must practice for at least [tex]$\dfrac{3}{2}$[/tex] hours each of the last two days.

Answer:

iii) P=65h

iv) P=70h

Step-by-step explanation:

Payment of First day = $300

Number of hours = 5

Payment per hour = $60

Payment of First day = $240

Number of hours = 4

Payment per hour = $60

Payment of First day = $360

Number of hours = 6

Payment per hour = $60

Hence the rate of Payment for an hour is $60

Hence the rates

P=65h

and

P=70h

are more than the rate of payment made to labor.

[tex]A=(1/2)[b1+b2]h[/tex]

In this problem we have

[tex]b1=12\ cm[/tex]

[tex]b2=6+12+2=20\ cm[/tex]

[tex]h=6\ cm[/tex] ----> perpendicular distance between the two bases

[tex]A=40.8\ ft^{2}[/tex]

Answer:

25) 96 cm²

26)  40.8 ft ²

Step-by-step explanation:

25) To find the area of trapezoid

Area of trapezoid = h(a + b)/2

Here a = 6 + 12 + 2 = 20 cm

b = 12 cm and h = 6

Area =  h(a + b)/2

 = 6(20 + 12)/2

 = 96 cm²

26) To find the area of kite

Area of kite = pq/2

Where p and q are the two diagonals

Here p = 10.2 ft and q = 8 ft

Area = pq/2

 = (10.2 * 8)/2 = 40.8 ft²

A quadrilateral with at least one pair of parallel sides.  

2. bases of a trapezoid

The parallel sides

3. legs of a trapezoid  

The nonparallel sides.  

4. median of a trapezoid  

The segment connecting the midpoints of the legs.  

5. isosceles trapezoid

A trapezoid with legs of the same length.

Answer:

A trapezoid is defined as a quadrilateral with at least one pair of parallel sides, when the trapezoid as equal legs, it's called an isosceles trapezoid.

The bases of a trapezoid are the pair of parallel sides, both of them are called base, the longer one is the major base, and the shorter one is the minor base.

The legs of a trapezoid are the nonparallel sides, because if they were parallel, that wouldn't be a trapezoid, it would be another quadrilateral.

The median of a trapezoid is a segment that connects the midpoints of the legs. Remember that medians are always line that intercept midpoints.

As we said before, an isosceles trapezoid are those which have legs with equal legs. The name isosceles refers to equality.

Therefore, the right matches are

1. Trapezoid: A quadrilateral with at least one pair of parallel sides.  

2. Bases of a trapezoid: The parallel sides.

3. Legs of a trapezoid: The nonparallel sides.  

4. Median of a trapezoid: The segment connecting the midpoints of the legs.  

5. Isosceles trapezoid: A trapezoid with legs of the same length.

y + 5 = - [tex]\frac{1}{2}[/tex](x + 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line.

y - 4 = 2(x - 6) is in this form with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

Hence the equation passing through (- 3, - 5) is

The fraction 5/9 cannot be converted into a whole number because it results in a decimal number (approximately 0.55) upon division.

In Mathematics, we have different types of numbers - whole numbers, fractions, decimals, etc. Here, you are asked to convert a fraction 5/9 into a whole number. However, it's essential to understand, that 5/9 cannot be converted into a whole number because it is less than 1.

For general understanding, a whole number can only be a non-negative number without any fractional or decimal parts, such as 0, 1, 2, 3, 4, and so forth. A fraction like 5/9 implies division, and when you divide 5 by 9, you get a decimal number (approximately 0.55), which is not a whole number.

Thus, the fraction 5/9 cannot be precisely converted into a whole number without rounding it off.

Set the divisor, 2x - 1, equal to zero and solve for x:  2x = 1, so x = 1/2.  Statement C is true.

Answer:

The correct option is C.

Step-by-step explanation:

If a function f(x) is completely divisible by (x-a), it means (x-a) is a factor of f(x) and x=a is a root of that polynomial.

The given polynomial is

[tex]P(x)=2x^2+9x-5[/tex]

It is given that when David divide the above polynomial by (2x-1), then he get

[tex]Quotient=x+5[/tex]

[tex]Remainder=0[/tex]

Since the remainder is zero it means P(x) is completely divisible by (2x-1) or (2x-1) is a factor of P(x).

[tex]2x-1=0[/tex]

Add 1 on both the sides.

[tex]2x=1[/tex]

Divide both sides by 2.
