Question 6 answer is 35

Step-by-step explanation:

using pythagoras theorem, hypotenuse²= opposite²+ adjacent²

since it is said that we're looking for the hypotenuse then the values given are for opposite and adjacent.

therefore, hyp²= 21²+28²

hyp²= 1225 take square root of both sides to eliminate square and find hypotenuse

hyp= 35

The data representation where the median is the better measure of the center is the third data representation.

From the information, the last bar graph is skewed to the right, since the values of its fourth and fifth bars are way smaller than the values of its first, second, and third graphs.

The drastically smaller values pull down the mean of the last bar graph. Comparatively, bar graphs one and two have symmetrical distributions of numbers on both sides of the central bar and this implies that their mean is balanced out on both sides and that neither of them is significantly skewed left or right.

Applying the law of cosine, the largest angle in the given triangle, to the nearest whole degree, is: 99°.

Law of cosine is, c² = a² + b² - 2ab(cosC)

Let,

Plug in the values into the formula for the law of cosine:

26² = 15² + 19² - 2(15)(19)(cosC)

676 = 586 - 570(cosC)

676 - 586 = -570(cosC)

90 = -570(cosC)

90/-570 = cos C

-0.1579 = cos C

C = cos^(-1)(-0.1579)

C = 99°

The largest angle = 99°

Using the permutation formula, as the order is important, it is found that the officers can be chosen in 6840 ways.

Each "position" is a different role(president, vice president and secretary), hence the order is important.

Answer:

Step-by-step explanation:

Perpendicular formula

m1 * m2 = - 1

Givens

m1 = - 7

m2 = ??

Solution

-7 * m2 = -1

m2 = 1/7

y = 1/7 x + b

x = 8

y = -3                     Substitute these values into y = 1/7 x + b

-3 = (1/7)*8 + b    

-3 = 8/7 + b          Subtract 8/7  from both sides

-3 - 8/7 = b

-4 1/7 = b

Answer (perpendicular line) y = (1/7) x - 4 1/7  or

Answer (perpendicular line) y = (1/7) x - 4.14

Nothing changes except you have a different y intercept.

y = -7x + b

x = 8

y = -3                           Substitute these values into y = -7x + b

The requried, factored form of the given expression is (x - 1)(x - 3)(x + 2).

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

To factor the polynomial f(x) = x³ – 2x² – 5x + 6 completely, we can use a combination of the rational root theorem and synthetic division.

We can use synthetic division to test each possible root and see if it is a factor of the polynomial. Starting with x = 2, we have:

2 | 1 -2 -5 6

  | 2 0 -10

  |_____________

1 0 -5 -4

Since the remainder is not zero, x = 2 is not a factor of the polynomial. Continuing with the other possible roots, we find that x = 1 and x = 3 are roots, but x = -1, x = -2, x = -3, and x = -6 are not roots.

Therefore, we can factor the polynomial as follows:

f(x) = x² – 2x² – 5x + 6

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

So the completely factored form of f(x) is f(x) = (x - 1)(x - 3)(x + 2).

Step-by-step explanation:

I think you made some mistakes in the problem definition.

I guess you mean

9 = (1/27)^(a+3)

let's think about how to create 9 out of 1/27 just by using exponents.

we note that 27 is 3³. and therefore the cubic root of 27 is 3.

so,

(1/27)^(1/3) = 1/3

because the exponent 1/3 means "cubic root". an exponent 1/2 means square root. and so on.

making the exponent negative means 1/...

so,

(1/27)^(-1/3) = 3

and now, with what exponent operation can we turn 3 into 9 ?

by squaring it.

so,

((1/27)^(-1/3))² = 9

putting an exponent on an exponent means to multiply the exponents during simplification.

therefore,

((1/27)^(-1/3))² = (1/27)^(-2/3) = 9

that means

a + 3 = -2/3

a = -2/3 - 3 = -2/3 - 9/3 = -11/3

so, the first answer option is correct.

Step-by-step explanation:

A woman gives 1/4 of a cake to her son 1/4 to her daughter, and 1/3 to her husband. What fraction is left?

As 4*3=12, we need to convert into twelfths.

3/12 + 3/12 + 4/12 = 10/12. This needs to be subtracted from 1 (12/12).

12/12 - 10/12 = 2/12. Simplify to 1/6.

1/6 is left.

The approximate measure of angle acb in right triangle abc in which the length of the hypotenuse, line segment ac is 25 cm is 53.1 degrees.

In a right angle triangle, ratio of the adjacent side to the hypotenuse side is equal to the cosine angle between them.

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 16 - 1 = 15 df, is t = 1.7531.

Researching the problem on the internet, the standard deviation was of 42.1 mg/dL, hence the parameters are as follows:

[tex]\overline{x} = 264.7, s = 41.2, n = 16[/tex]

Thus, the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 264.7 - 1.7531\frac{41.2}{\sqrt{16}} = 246.6[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 264.7 + 1.7531\frac{41.2}{\sqrt{16}} = 282.8[/tex]
