Which trigonometric ratio for a˚ belongs with each value. Enter sin, cos, or tan in each box.
A right angle triangle with one angle a degree. The adjacent sides 6 and opposite side is 9. The hypotenuse 3 square root of 13.
= 313√13
= 213√13
= 32
Hey there! I'm happy to help you!
When talking about trigonometric ratios, we can use a handy little mnemonic device called soh cah toa which shows us the ratios for each one. Soh is sine equals opposite over hypotenuse, cah is cosine equals adjacent over hypotenuse, and toa is tangent equals opposite over adjacent.
In our triangle, we can apply the following with the given information.
[tex]sin=\frac{opposite}{hypotenuse} =\frac{9}{3\sqrt{13} } =\frac{3}{\sqrt{13} } =\frac{3\sqrt{13} }{13} \\\\cos=\frac{adjacent}{hypotenuse} =\frac{6}{3\sqrt{13} } =\frac{2}{\sqrt{13} } =\frac{2\sqrt{13} }{13} \\\\tan=\frac{opposite}{adjacent} =\frac{6}{9} =\frac{2}{3}[/tex]
Therefore, the answers will be sin, cos, and then tan going down in the answer order you gave!
I hope that this helps! Have a wonderful day!
Segments AB, DC and Ec intersect at point C. Angel DCE measures 148. Find the value of x.
The image is attached.
Answer:
x = 16°
Step-by-step explanation:
Segment AB, segment DC and segment EC all intersect at point C.
Here, we are told angle DCE measures 148°.
This is a semi-circle, and the total angle of a semi-circle is 180°.
Which means, x+x+148 = 180
Solving for x, we have:
x+x+148 = 180
2x + 148 = 180
2x = 180 - 148
2x = 32
[tex]x = \frac{32}{2}[/tex]
x = 16°
The value of x is 16°

What type of function is represented in the table? x|0|1|2|3|4|5|
A exponential B logarithmic C linear D quadratic. y|-1|0|-3|-10|-21|-36|
Answer:
This may be wrong but im guessing it is B.logarithmic
Step-by-step explanation:
The type of function is Quadratic.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
x 0 1 2 3 4 5
y - 1 0 - 3 - 10 - 21 - 36
As, we can see from the table ,
The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.
However, the second differences are all equal to -4, which indicates that the function has a quadratic form.
Hence, the function is quadratic.

Which choice is equivalent to the quotient shown here for acceptable values of x?
Answer:
(D)
Step-by-step explanation:
Equivalent expressions are expressions that have equal values
The equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]
The expression is given as:
[tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex]
Represent the expression as a quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x^2}{3x}}[/tex]
Evaluate the quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x}{3}}[/tex]
Hence, the equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]

Answer:
d =13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance across the circle, going through the center
d = 13 cm
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm
Answer:
Radius is 6.5
Diameter is 13
Step-by-step explanation:
The diameter is the distance across the circle. The radius is half the distance across the circle.

10. Two sides of a triangle have
the following measures. Find the
range of possible measures for
the third side.
35, 29
7
6
8
9
Answer:
The range of possible measures for the third side are 6 < x < 64.
Step-by-step explanation:
The sum of two sides of a triangle is always greater than the third side.
The two sides of a triangle are:
A = 35
B = 29
Suppose the third side is, C = x.
Then,
A + B > C
⇒ 35 + 29 > x
⇒ 64 > x
⇒ x < 64
But for the inequality theorem to be consistent for all the three sides, the third side must have a lower bound.
The difference between the two provided side is,
Diff = 35 - 29 = 6
The third side should not be less than 6 for the inequality theorem to hold.
Thus, the range of possible measures for the third side are 6 < x < 64.

The average age of people attending a concert was 23 years old, with a standard deviation of 7. What percentage of people at the concert were older than 37 years old?
Answer:
2.28%
Step-by-step explanation:
We have that the mean (m) equals 23 and that the standard deviation (sd) is 7.
We can calculate the value z and in this way we can calculate the probability in this case with the calculation of the normal distribution table:
z = m - x / sd
we know that x is 37, replacing:
z = (23 - 37) / 7
z = -2
according to the normal distribution table the value of z = -2, is equivalent to 0.0228
So the probability is 2.28%
