Answer: 110 degrees
Step-by-step explanation:
We know that all the angles of a triangle add to 180 degrees. Notice how there are already 60 and 50 degrees on the triangle. In order to find the last angle, we subtract 110 (60+5) from 180 to get 70.
Now, we know that the angle of a straight line is 180.
So, in order to find <BCD, take 70 and subtract it from 180.
Doing this, we find that m<BCD is 110 degrees

After simplifying the radical expression 5 √(-64) x¹⁴ y²⁰, the result is 40 x¹⁴ y²⁰ i.
We are given the radical expression as:
5 √(-64) x¹⁴ y²⁰
We need to simplify the radical expression and find the value of the expression.
Now, we will first simplify the term √(-64)
We know that:
√(-64) = √( - 1 × 8 × 8 )
= 8 √ -1
Using the properties of complex numbers, we get that:
√ - 1 = i
= 8 i
Putting it in the expression, we get that:
= 5 ( 8 i ) x¹⁴ y²⁰
= 40 x¹⁴ y²⁰ i
Therefore, we get that, after simplifying the radical expression 5 √(-64) x¹⁴ y²⁰, the result is 40 x¹⁴ y²⁰ i.

y = 3x -5 is the equation of the line parallel to the line and going through the point (4,7). The format is slope intercept.
Slope intercept is what?A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.
Using the information provided,
y= 3x – 5
First, we must keep in mind that parallel lines have an equal slope.
In essence,
m1 = m2 if line 1 and 2 are parallel.
Y = mx + c is the slope-intercept form of the equation; y = 3x + 6, which already has this form.
incline of the m1 = 3.
Consequently, m1 = 3 = m2.
The slope of the parallel line, m2 = 3 and the line passes through the point (4,7).
Therefore;
3 = (y - 7)/(x-4)
By cross product;
3x - 12 = y - 7
y = 3x - 5

we can state that Option D may be accurate and true.
Assuming that the function, g, it has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18 and that g(-1) = 2 and g(2) = 8
Then the following properties must hold
1. The value(s) of x must be between -1 and 4
2. The values of g(x) must be between 0 and 18.
3. g(-1)=2
4. g(2)=9
We consider the options and state why they are true or otherwise.
A: g(5)=12
The value of x=5. This contradicts property 1 stated above. Therefore, it is not true.
B: g(1) = -2
The value of g(x)=-2. This contradicts property 2 stated above. Therefore, it is not true.
C: g(2) = 4
The value of g(2)=4. However by property 4 stated above, g(2)=9. Therefore, it is not true.
D: g(3) = 18
Given that its domain is between -1 and 4 and its range is between 0 and 18, this claim is reasonable.
Therefore, we can say that Option D can be true.

The given expression can be simplified by using rules of exponents.
There will be two rules applied, one for negative exponent and other for multiplication of exponents.
The expression can be solved by using either of the rules first. In this case, we will solve for the negative exponent first.
The base term x has a negative exponent of -4/7. The negative exponent rules states that the term with the negative exponent can be expressed in a reciprocal or reverse form without the negative sign.
In the general form, x^-a=1/x^a.
Applying the rule here,
(x^⁻⁴/₇)^7=(1/x^4/7)^7
Now multiplying the powers and simplifying,
(1/x^4/7)^7=1^7/x^(4/7)*7=1/x^4

if the point P(-4/5,y) lies on the unit circle and P is in the third quadrant, what does y equal
Answers
The value of y on the unit circle is y =-3/5
What is a circle?A circle is defined as the locus of a point such that it is equidistant from a fixed point.
The equation of a circle with center at the origin is given by x² + y² = r² where r = radius of circle
What is a unit?A unit circle is a circle with radius, r = 1.
So, the equation of a unit circle is x² + y² = 1
How to find the value of y on the unit circle?Given that the point P(-4/5, y) lies on the unit circle, and P is int he third quadrant, making y subject of the formula in the equation for unit circle, we have
y = ±√(1 - x²)
Substituting x = -4/5 into the equation, we have
y = ±√(1 - x²)
y = ±√(1 - (-4/5)²)
y = ±√(1 - 16/25)
y = ±√[(25 - 16)/25]
y = ±√[9/25]
y = ±3/5
Now, given that P is in the third quadrant, it implies that y is negative. so, y = -3/5
So, the value of y on the unit circle is y =-3/5

please find the area of the circle on the outside . and write the formula please thank you !!
Answers
first, you want to find the area of the whole circle. the formula for the area of a circle is pi r squared where r = radius
so we need radius squared x pi (3.14)
the radius of the big circle is 8. 8 squared is 64. 64 times 3.14 is 200.96
so the area of our big circle is 200.96
then, we need to subtract the area of the smaller circle. we know that the width of the shaded part is 3cm. the width of the bigger circle is 8cm (also the radius). so the radius of the smaller circle is 8-3, which is 5
now we can use the circle formula to find the area of the smaller circle (pi r squared)
5 squared is 25. 25 x 3.14 is 78.5.
now we subtract the area of the smaller circle. 200.96 minus 78.5 is 122.46.
the area of the shaded region in 122.46

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
