Right Triangle ABC has its right angle at C, BC = 4, and AC= 8.
What is the value of the trigonometric ratio?
cos B
csc B
tan A
Drag a value to each box to match the trigonometric ratio?
Answers

Answer:
cos B = (√5)/5
csc B = (√5)/2
tan A = 1/2
Step-by-step explanation:
The length of hypotenuse AB is given by the Pythagorean theorem:
AB² = AC² +BC²
AB² = 8² +4² = 64 +16 = 80
AB = √80 = 4√5
The mnemonic SOH CAH TOA can help you remember the needed ratios.
Cos = Adjacent/Hypotenuse
cos B = BC/AB = 4/(4√5)
cos B = (√5)/5
__
Sin = Opposite/Hypotenuse
csc = 1/sin = Hypotenuse/Opposite
csc B = AB/AC = (4√5)/8
csc B = (√5)/2
__
Tan = Opposite/Adjacent
tan A = BC/AC = 4/8
tan A = 1/2
Answer:
tan A = 1/2
cos B = √5/5
csc B = √5/2

Determine whether the graph of the quadratic function y = –3x2 + 2x + 5 opens upward or downward. Explain.
Answers
Answer:
The graph of the function opens downwards.
Step-by-step explanation:
The graph opens upward if the coefficient of x^2 is higher than 0.
But, the coefficient of x^2 (-3) is less than 0.
So the graph of the function opens downwards.

write the equation of a line that passes through the point ( -1, 5) and has a slope of -7
Answers
Answer:
[tex]y=-7x-2[/tex]
Step-by-step explanation:
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
Let (-1, 5) be (x₁, y₁) and our slope m is -7. By substitution:
[tex]y-(5)=-7(x-(-1))[/tex]
Distribute:
[tex]y-5=- 7 x - 7[/tex]
Adding 5 to both sides gives us our equation:
[tex]y=-7x-2[/tex]

Step 1: 12x – 15 – 12x = 7x + 20
Step 2: 12x – 12x – 15 = 7x + 20
Step 3: -15 = 7x + 20
Step 4: -35 = 7x
Step 5: -5 = 3
Drag and drop the correct justification for each step.
Answers
Step-by-step explanation:
step 1. 12x - 15 - 12x = 7x + 20
step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)
step 3. -15 = 7x + 20 (adding like terms)
step 4. -35 = 7x (subtract 20 from both sides)
step 5. this step is incorrect.
step 6. -5 = x ( divide both sides by 7)
step 7. x = -5 (put the variable first).
Given the following number as an approximate measurement, 49.5 feet. What is the range of values for the actual value?
Answers
Answer:
range is 2
Step-by-step explanation:
The range of values for the actual value is 2.
A range is the simplest measurement of the difference between the values in a dataset. To find the range, subtract the minimum value from the maximum value and ignore the other values. Where the minimum is 155 and the maximum is 720.
The statistical range for a particular dataset is the difference between the maximum and minimum values. For example, if the specified record is {2,5,8,10,3}, the range is 10 – 2 = 8. Therefore, the range can also be defined as the difference between the highest and lowest observations.

Answers
Answer:
A. y = 2
B. x = 7/2
C. y = 12/5
D. x = 6
Step-by-step explanation:
A. Determination of y .
2x + 5y = 12
x = 1
2(1) + 5y = 12
2 + 5y = 12
Collect like terms
5y = 12 – 2
5y = 10
Divide both side by 5
y = 10 / 5
y = 2
B. Determination of x
2x + 5y = 12
y = 1
2x + 5(1) = 12
2x + 5 = 12
Collect like terms
2x = 12 – 5
2x = 7
Divide both side by 2
x = 7/2
C. Determination of y
2x + 5y = 12
x = 0
2(0) + 5y = 12
0 + 5y = 12
5y = 12
Divide both side by 5
y = 12/5
D. Determination of x
2x + 5y = 12
y = 0
2x + 5(0) = 12
2x + 0 = 12
2x = 12
Divide both side by 2
x = 12/2
x = 6
