Answer 1
Answer:

Answer:

tan(\theta) = (3)/(4)

Step-by-step explanation:

Remember the trigonometric ratios, keep in mind that the way the side is referred to is based on its position relative to the angle getting referenced. The side next to the referenced angle (\theta) is called the adjacent side, the one opposite the angle is called the opposite side, and the side opposite the right angle of the triangle is called the hypotenuse.

sin (sine) = (opposite)/(hypotenuse)\n\ncos (cosine) = (adjacent)/(hypotenuse)\n\ntan(tangent) = (opposite)/(adjacent)

In this problem, one is asked to find the value of (\theta) with regards to a trigonometric function. One is given the opposite and adjacent sides, it would make the most sense to use the trigonometric function (tangent). Substitute the sides into their respective place, and simplify to find the value of the trigonometric function.

tan(\theta) =(15)/(20)\n\n\ntan(\theta)=(3)/(4)

if the perimeter of a rectangle picture frame must be less than 180 in., and the width is 26 in. what must the height h of the frame be?

Answers

180 > 2(26) + 2h 
180 > 52 + 2h 
128 > 2h 
64 > h 
height must be less than 64 inches

The sum of 3 consecutive integers is -192. What is the middle number?

Answers

-192 ÷ 3 = -64

therefore the numbers must be -63, -64, and -65

the middle number is -64 :)
 the middle number is -64 , because -192 / 3

Find the balance in the account. $700 principal earning 5%, compounded monthly, after 9 years

Answers

Answer: The balance in the account after 9 years is $1085.93.

Step-by-step explanation:

Since we have given that

Principal amount = $700

Rate of interest = 5%

Number of years = 9

Since we have mentioned to use "Compound Interest " method:

As we know the formula for above i.e.

A=P(1+(r)/(100))^n\n\nA=700(1+(5)/(100))^9\n\nA=\$1085.93

Hence, the balance in the account after 9 years is $1085.93.
A=700×(1+0.05÷12)^(12×9)
A=1,096.79

Rite an equation of a line parallel to line EF in slope-intercept form that passes through the point (2, 6).E
Oy=2x+3
Oy = 3x + 6
F
Oy=-3x+23
Oy=-3x+6
22

Answers

The equation of a line parallel to line EF in slope-intercept form is Oy = 2x + b, where b is the y-intercept.

To determine the value of b, we will use the fact that this line passes through the point (2, 6).

Plugging in the x-coordinate of the point (2, 6) into the equation Oy = 2x + b, we get:

6 = 2(2) + b

6 = 4 + b

Subtracting 4 from both sides, we get:

2 = b

Therefore, the equation of the line parallel to line EF in slope-intercept form that passes through the point (2, 6) is:

Oy = 2x + 2.

What is the range and domain of the function : y= sqrt(x) -5 ... Can you please explain? Thanks btw the square root is only over the x

Answers

Domain of √(x) - 5 :  x ≥ 25 .

Range of   √x - 5 : y ≥ -5 .

Given,

f(x) = √x - 5

Here,

To find the domain,

√x - 5 ≥ 0

√x ≥ 5

Squaring both sides ,

x ≥ 25 .

Thus domain of √x - 5 is x ≥ 25 .

Range of √x - 5,

To define the range of the function the value of x can not be negative as it will make the function complex .

So,

Range will be ,

y ≥ -5 .

Know more about domain and range,

okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0

for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.
