Answers

Answer 1

Answer:

The correct answer is C

Step-by-step explanation:

In a function, no two ordered pair has the same first element. if you check all the Rest, they have one or more two ordered pairs having the same first element. But C has unique first ordered elements, -1, 4, 1 and -3

Given: PB tangent PV, PU secants

angle1=30 and mSTarc= 20, then mVUarc=___​

Answers

Answer:

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

⇒ Measurement of the arc VU= 80°.

Answer:

80 is the correct answer

1 7/10 - 1 1/2
it has to be a fraction and no links

Answers

First you start solving each mixed fraction:
17/10 - 3/2
Now we have improper fractions; fractions that have a numerator larger than the denominator
Next we will find the common denominator using LCM but what I personally do is I multiply both sides by the opposite fraction’s denominator, like this:
17 x 2 _ 3 x 10 —-> 34 - 30
10 x 2 2 x 10 20 - 20

Now we have 34/20 - 30/20 and with the help of collecting the common denominator, all we have to do now is subtract 30 from 34, and our answer will be 4/20
**when we have the same number as our denominator we only add or subtract the numerator, depending on what question your teacher asks you to answer
*** sum = addition/adding
difference = subtraction/subtracting/taking away
The correct answer is 1/5
At first when you subtract you will get 4/20 however answers should always be in reduce /simplified do answer is
1/5

Write the equation of the line in fully simplified slope-intercept form.

Answers

Answer:

[tex]y=-\frac{1}{4} x-6[/tex]

Step-by-step explanation:

The slope-intercept form is [tex]y=mx+c[/tex], where m is the slope of the line and c is where the line crosses the [tex]y[/tex]-axis.

To calculate [tex]m[/tex] we can use the formula [tex]m = \frac{dy}{dx}[/tex] where [tex]dy[/tex] is the difference in [tex]y[/tex] between two points and [tex]dx[/tex] is the difference between [tex]x[/tex].

Information we can get from the graph given: [tex]c=-6[/tex]. Since [tex]c[/tex] is the point at which the line crosses the [tex]y[/tex]-axis.

To find [tex]m[/tex] let's get two points from the graph.

Point 1: [tex](4,-7)[/tex]

Point 2: [tex](8,-8)[/tex]

Now use the equation [tex]m = \frac{dy}{dx}[/tex].

[tex]m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}[/tex].

Now we have [tex]m[/tex] and [tex]c[/tex], let's put them back into the general equation.

[tex]y=-\frac{1}{4} x-6[/tex]

know how long it will take an investment of $1,000
to earn $500 in interest if the yearly interest rate is 4.75%. Please answer fast and show work I will mark you as brain

Answers

Answer:

It will take 8.73 years.

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $1,000

Future value (FV)= $1,500

Interest rate (i)= 4.75% compounded annually

To calculate the time required for the initial investment to reach the objective, we need to use the following formula:

n= ln(FV/PV) / ln(1+i)  

n= ln(1,500/1,000) / (1.0475)

n= 8.73

It will take 8.73 years.
