What is the slope of a line perpendicular to this line? Y=-1/4x+5

1 answer:

IRISSAK [1]3 years ago

Answer:

4

Step-by-step explanation:

Two perpendicular lines must have a slope that multiplies to -1. With this in mind, we take the slope from the given equation, -1/4, and add multiply it by a variable new slope, z. We get the equation -1=-1/4z

Working it out:

-1=-1/4z

-1/-1/4=-1/4z/-1/4 (The two -1/4's on the right cancel out, leaving us with just z on the right side. -1 divided by -1/4 is equal to 4)

4=z

The slope of your line perpendicular to the given line is 4.

A trick for me to remember this is the answer for a perpendicular slope is the negative reciprocal. Add a negative sign to the number and flip it. It will never be wrong if worked out correctly. I can help you with this strategy more if you ask.

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being

ladessa [460]

Using the probability concept, it is found that there is a $\mathbf{\frac{1}{k}}$ probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

There is a total of k documents to be reviewed, hence $T = k$ .
Of those documents, 1 is named “Relaxation Through Mathematics”, hence $D = 1$

The <em>probability </em>is:

$p = \frac{D}{T} = \frac{1}{k}$

A kite is flying 300 feet above the person flying it. The angle of depression to the person holding the kite is

Triss [41]

Answer:

the answer i got was 1159.1

Step-by-step explanation:

cos75 = 300/x

0.25881905 = 300/x

multiply everything by x

0.25881905x = 300

Divide everything by 0.25881905

x = 1159.1

is that close to any of your answers?
