I need help with math I tried my best but couldn’t get it

Mathematics
1 answer:
notsponge [240]3 years ago
3 0

Answer:

Step-by-step explanation:

1. Convert to slope intercept form (y=mx+b)

2. Find slope (the 'm' in mx)

3. Find slope of perpendicular line

So for the first question:

Convert to slope Intercept form if necessary:

3x+4y=12

4y=12-3x<<Subtract by 3x

y=3-<u>3/4</u>x<<Divide by 4

Find slope

y=3-<u>3/4</u>x

3/4 is the slope

Find slope of perpendicular line

To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.

Here is what I mean:

3/4<<original slope

4/3<<reciprocal

-4/3<<opposite

So for the first question -4/3 is the answer.

Now you can do the rest! Hope this helps!

(If you have more questions feel free to comment to let me know!)

Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest poss
julia-pushkina [17]

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

$c^2 > a^2 +b^2$

$c^2 > (9)^2 +(14)^2$

$c^2 > 81 +196$

$c^2 > 277$

c > 16.64

Therefore the smallest possible whole number is 17 inches.

Flura [38]

Answer:

The probability that she will escape detection for at least three years is P=0.343.

Step-by-step explanation:

If Jody has a 30% chance each year of having her tax returns audited, she also has 70% chance each year of escaping detection.

The probability of this happening 3 years in a row is:

P_n=q^n=0.7^3=0.343
