[tex]5\frac{3}{8} = \frac{43}{8} [/tex]

Expressing 5 3/8 as an improper fraction would be written as 43/8

Given the fraction which is need for our Calculation:

Improper fractions have their Numerator values greater than the denominator

Hence, we have :

Therefore, the improper fraction representation is 43/8.

Answer:

1.36

Step-by-step explanation:

Answer:

The amount is 5,955.08

Step-by-step explanation:

Here, we want to calculate compound interest

We can find this by using the compound interest formula

A = P( 1 + r/n)^nt

A is amount

P

is the principal = 5,000

r is the interest rate = 6% = 6/100 = 0.06

n is the number of times per year in which the interest is compounded = 1

t is the number of years = 3

Substituting these values;

A = 5,000(1 + 0.06/1)^3(1)

A = 5000(1.06)^3

A = 5,955.08

Answer:

F 8.4

Step-by-step explanation:

4 [ 4.5 - 2(1.2)]

First, multipy 2 and 1.2

2 x 1.2 = 2.4

Then subtract 2.4 from 4.5

4.5 - 2.4 = 2.1

Last, multiply 2.1 from 4

4 x 2.1 = 8.4

Answer:

(4x + 7)(x - 2)

Step-by-step explanation:

Synthetic division can be a very useful tool in factoring, although there are certainly other methods.

-14 is the constant term; its factors here MAY include ±2 and/or ± 7.

Let's use synthetic division to determine whether or not 2 is a root of the quadratic:

2   /   4    -1    -14

               8     14

    --------------------

         4     7      0

Because the remainder here is zero (0), we have verified that 2 is a root and (x - 2) is a factor of 4x^2 - x - 14.  Note that the remaining coefficients, 4 and 7, indicate that the other factor is 4x + 7.

Thus, 4x^2– x - 14 = (4x + 7)(x - 2)

Answer:

2cos(3x)

Step-by-step explanation:

If the function were just cos(x), then the second peak would happen at 2π.  Instead though, it happen 2π / 3.   That means that the coefficient of x must be 3.

At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.

That tells us that the function graphed here must be 2cos(3x).

The correct answer is option A which is the equation of the given graph is y = 2cos(3x)

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

If the function were just cos(x), then the second peak would happen at 2π.  Instead, though, it happens 2π / 3.   That means that the coefficient of x must be 3.

At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.

Therefore the correct answer is option A which is the equation of the given graph is y = 2cos(3x)

We are given with information that , we have to find two consecutive positive integers , sum of whose squares is 365 .

[tex]{\pmb{\bf Assumption \: :-}}[/tex] Let's assume that the first number is x , and as the other no. is it's consecutive so , the second no. is (x+1)

Now , According to the question ;

[tex]{: \implies \quad \sf x^{2}+x^{2}+1^{2}+ 2\cdot x \cdot 1 = 365\quad \{\because (a+b)^{2}=a^{2}+b^{2}+2ab\}}[/tex]

Can be further written as ;

[tex]{: \implies \quad \sf 2{x^{2}}+2x -364=0}[/tex]

[tex]{: \implies \quad \sf 2(x^{2}+x-182)=0}[/tex]

As , [tex]\sf 2 \neq 0[/tex] . So ;

[tex]{: \implies \quad \sf x^{2}+x-182=0}[/tex]

Using splitting the middle term ;

[tex]{: \implies \quad \sf x^{2} +14x-13x-182=0}[/tex]

[tex]{: \implies \quad \sf x(x+14)-13(x+14)=0}[/tex]

[tex]{: \implies \quad \sf (x+14)(x-13)=0}[/tex]

When (x+14) = 0 , then x = - 14 , which is rejected as it's not +ve

When (x-13) = 0 , then x = 13 , which is +ve

Now ,

Hence , The required numbers are 13 and 14 respectively .

Answer: Corresponding

Step-by-step explanation:

They aren’t opposing therefore it can’t be vertical. The are not on the outside therefore it can’t be alternate exterior. The angles also fall on the same line, therefore it’s corresponding.
