If sin A = cos B and the measure of angle A is 1.5 times the measure of angle B, find the measure of angle A

Answers

Answer:

[tex]A = 54[/tex]

Step-by-step explanation:

Given

[tex]\sin A = \cos B[/tex]

[tex]A=1.5B[/tex]

Required

Find A

If [tex]\sin A = \cos B[/tex]

Then:

[tex]A +B = 90[/tex]

Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]

[tex]1.5B + B = 90[/tex]

[tex]2.5B = 90[/tex]

Solve for B

[tex]B = \frac{90}{2.5}[/tex]

[tex]B = 36[/tex]

Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]

[tex]A = 1.5 * 36[/tex]

[tex]A = 54[/tex]

Answer:

Answer B

Step-by-step explanation:

You have to use the pythagorean theorm which states that a^2+b^2=c^2

So, 7^2+x^2=9^2

49+x^2=81 subtract 49 from both sides of the equation

x^2=32

x=sqrt(32)

sqrt(32)=sqrt(16)*sqrt(2)

The minimum and maximum values are negative 1/4 and 9/4. In the interval of (0, π/2), the function is decreasing. And the range of the function will be [–1/4, 9/4].

What is a sinusoidal Function?

It is a function that repeats itself in a particular time interval.

The equation is given as

y = A sin (ωx + Ф) + C

Where A is the amplitude, ω is the frequency, Ф is the phase difference, and C is the constant.

The function is given below.

f(x) = (5/4) sin(x) + 1

Compare the function with standard equation.

A = 5 / 4

ω = 1

Ф = 0

C = 1

Then the maximum value of the function at sin x = 1, will be

Maximum value = 5/4 + 1

Maximum value = 9/4

Then the minimum value of the function at sin x = –1, will be

Minimum value = –5/4 + 1

Minimum value = –1/4

In the interval of (0, π/2), the function is decreasing.

And the range of the function will be [–1/4, 9/4].

Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid

Answers

Complete question :

Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid between 15500 and 17000

Answer:

49.85%

Step-by-step explanation:

Mean = 17000

Standard deviation = 500

Obtain the Z score, which is the number of standard deviations from the mean :

((17000 - 17000) / 500) = 0

((15500 - 17000) / 500) = - 3

-3 to 3 = (3 standard deviations)

However,

The value here is (-3 to 0) ; which is only 3 standard deviations to the left.

3 standard deviation = 99.7% (empirical rule)

Since it is only (-3 to 0) ; which is only 3 standard deviations to the left. ; the percentage will be halved

99.7% / 2 = 49.85%

Hence, percentage of buyers who paid between 15500 and 17000 is 49.85%

What was the median price of the items?
MEAN AND MEDINA

Answers

Answer:

Mean is 5.2 Median is $6.00

Step-by-step explanation:

To find mean u have to find the "average" whereby u add all the numbers and divide by the number of numbers.

($2+$4+$6+$6+$8)= $26. Then since there are 5 numbers in all u divide by 5.

$26÷5 =5.2 5.2 is the median.

Median is the middle number. To find it u have to rearrange the numbers from smallest to largest and find the middle number.

$2, $4, {$6,} $6, $8

$6 is the median.

Answers

Answer:

x = 135

Step-by-step explanation:

(100 + 121 + 105 + 113 + 108 + x) /6 = 112

(547 + x) /6 = 112

547 + x = 112 × 6

547 + x = 672

x = 672 - 547

x = 135

[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = 6 ÷ - 2 = - 18 ÷ 6 = 54 ÷ - 18 = - 3

This indicates the sequence is geometric with explicit formula

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = - 3 , then

[tex]a_{n}[/tex] = - 2 [tex](-3)^{n-1}[/tex]
