Answer:

Measure of arc CD = 112°

Step-by-step explanation:

Since quadrilateral ABCD is a cyclic quadrilateral,

m∠A + m∠C = 180°

129° + m∠C = 180°

m∠C = 180° - 129°

m∠C = 51°

Since, m(arc BD) = 2(m∠C) [Since measure of the arc is double of its inscribed angle]

                           = 2(51°)

                           = 102°

Since, m(arc BD) + m(arc CD) + m(arc BC) = 360°

102° + m(arc CD) + 146° = 360°

m(arc CD) = 360° - (102° + 146°)

                = 112°

Therefore, measure of arc CD is 112°.

What is the minimum value?
valentinak56 [21]

Answer:

The minimum value of a function is the lowest point of a vertex. If your quadratic equation has a positive a term, it will also have a minimum value. ... If you have the equation in the form of y = ax^2 + bx + c, then you can find the minimum value using the equation min = c - b^2/4a.

How can you tell the difference between debit and credit​
TiliK225 [7]

Answer:

When you use a debit card, the funds for the amount of your purchase are taken from your checking account in almost real time. When you use a credit card, the amount will be charged to your line of credit, meaning you will pay the bill at a later date, which also gives you more time to pay.

1. What is the value of the expression f2 + 5 if f = 3?<br> A. 8<br> B. 2<br> C. 6<br> D. 14
zaharov [31]

Option D: 14 is the right answer

Step-by-step explanation:

In order to find the value of given expression we have to put the given value for f in the expression

Given expression is:

f^2+5

We have to find the value of expression on f=3

So,

putting f=3 in expression

= (3)^2+5\\= 9+5\\=14

The value of given expression at f=3 is 14

Hence,

Option D: 14 is the right answer

Write an equation in slope intercept and form of the line through point(6,-1)with slope m=4
aniked [119]

To solve this problem, we must first remember that slope-intercept form is y=mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the equation.

To begin, we can take this form and substitute in the slope for the variable m.

y = mx + b

y = 4x + b

Next, because we weren't given the y-intercept, we can find it by substituting the value of 6 for x and the value of -1 for y (these values came from the ordered pair that we were given in this problem).

-1 = 4(6) + b

After that, we can begin to simplify and solve for the variable b by computing the multiplication on the right side of the equation.

-1 = 24 + b

Next, we should subtract 24 from the right side of the equation in order to get the variable b alone.

-25 = b

Now, if we substitute in this value for the variable b in our equation with the slope, we get:

y = 4x - 25

Therefore, your answer is y = 4x - 25.

Hope this helps!
