A1 or just a as it is in the equations is just the initial term of the sequence. In this case a1=1

r is the common ratio which is that constant ratio found by dividing any term by the term preceding it...

In this case r=3/1=9/3=27/9=etc=3

So a1=1 and r=3, C. is your answer.

What is the slope and y-intercept of this equation? y = 5x

denis-greek [22]

Answer:

Slope- 5 y-int- (0,0)

Step-by-step explanation:

y=mx+b, where m=slope and b=y-int. m=5, and we don't see a b, so it must be 0.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify

Leg a = 24

Leg b = 7 in

Leg c = x

Step 2: Solve for x

Substitute in variables [Pythagorean Theorem]: 24² + 7² = x²
Evaluate exponents: 576 + 49 = x²
Add: 625 = x²
[Equality Property] Square root both sides: 25 = x
Rewrite/Rearrange: x = 25

Pls help me guys, I’d really appreciate it

Answer:

∠ PQR = 70°

Step-by-step explanation:

The tangent- tangent angle PQR is half the difference of the intercepted arcs.

minor arc PR = 360° - 250° = 110°

Then

∠ PQR = $\frac{1}{2}$ (250 - 110)° = $\frac{1}{2}$ × 140° = 70°

"let v be the event that a computer contains a virus, and let w be the event that a computer contains a worm. suppose p(v) = 0.1

morpeh [17]

Here we might have to find p(v intersection w) and for that we use the following formula

p(v U w) = p(v)+p(w)-p(v intersection w)

And it is given that p(v) =01.3 , p(w) = 0.04 and p(v U w ) = 0.14 .

Substituting these values in the formula, we will get

0.14 = 0.13 +0.04 -p(v intersection w)

p(v intersection w) =0.13 +0.04 -0.14 = 0.03

So the required answer of the given question is 0.03 .
