What is an equation in point line slope form of the line that passes through the point (4,-1) and had slope 6
Answer:
y+1=6(x-4)
This is if you want it in point slope for,.
Step-by-step explanation:
Then, if you simplify it.
y+1=6x-24
y=6x-25
Now, it is in slope intercept form.

I think it's a pattern, so x would be 3 and y would be 5 for the first one
x would be 20 for the second
and i dont even do word problems so...

Decrease 40 by ratio of 4:5
A decrease in the ratio 4:5 implies that :
New quantity:Old quantity = 4:5
Let the new quantity be [tex] \bf \: x[/tex]
[tex] \bf∴ x : 40 = 4:5[/tex]
[tex] = > \bf \frac{x}{40} = \frac{4}{5} [/tex]
[tex] \bf = > 40 \times \frac{x}{40} = 40 \times \frac{4}{5} [/tex]
[tex] \bf = > x = 8 \times 4[/tex]
[tex] \bf = > x = 32[/tex]
So, the new quantity is 32
A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12 more feet to get a better look at a coral reef.
Complete question :
A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12
more feet to get a better look at a coral reef.
What is the scuba diver's final position relative to sea level?
Answer:
- 22 feets
Step-by-step explanation:
Given that:
Starting position of scuba diver = 10 feets below sea level = - 10 feets
Then a further descent of 12 feets in other to get a better look of the coral Reef
Further descent = - 12 feets (below sealevel)
Hence, Final position of the scuba diver will be:
Starting position + depth of further descent
(-10 + - 12) feets
-22 feets

PLEASE HELPP! The diameter of a decorated plate is 20 centimeters. There is a flower painted every 15.7 centimeters around the edge of the plate. How many flowers are painted on the plate? Use 3.14 for
Answer:
4 flowers
Step-by-step explanation:
First we need to calculate the circumference of the plate.
C = πd
Given
diameter d = 20cm
C = 3.14(20)
C = 62.8 cm
If there is a flower painted every 15.7 centimeters around the edge of the plate, the amount of flower on the plate will be;
Number of flower = Circumference of the plate/length of flower
Amount of flower = 62.8/15.7
Amount of flower = 4
Hence there are 4 flowers painted on the plate

A new cars salesperson, sold an average of $28,000 per day for the first 5 days she worked.
The next 3 days she worked, she sold an average of $42,000. How much did she sell on average
per day over the entire 8 days?
Answer: 15
Step-by-step explanation:
The average number of cars sold for entire 8 days is $33250.
What is the average?In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
Given that, a new cars salesperson, sold an average of $28,000 per day for the first 5 days she worked.
So, number of cars sold for 5 days =28,000×5
= 140000
The next 3 days she worked, she sold an average of $42,000.
Number of cars sold for 3 days
= 42,000×3
= 126000
So, average of 8 days =(140000+126000)/8
= 266000/8
= 33250
Therefore, the average number of cars sold for entire 8 days is $33250.

How do I find the 5 roots of 1^(1/5) using De Moivre's Theorem?
Do you mean the 5th roots of 1? Or the 5th roots of 1^(1/5), i.e. the 5th roots of the 5th roots of 1?
I assume you mean the former. To begin with,
1 = exp(0°i ) = cos(0°) + i sin(0°)
Take the 5th root, i.e. (1/5)th power of both sides, so that by DeMoivre's theorem,
1^(1/5) = [ cos(0°) + i sin(0°) ]^(1/5)
1^(1/5) = cos((0° + 360°n)/5) + i sin((0° + 360°n)/5)
where n = 0, 1, 2, 3, or 4. Then 1^(1/5) has the 5 possible values,
• cos(0°/5) + i sin(0°/5) = 1
• cos(360°/5) + i sin(360°/5) = cos(72°) + i sin(72°)
• cos(720°/5) + i sin(720°/5) = cos(144°) + i sin(144°)
• cos(1080°/5) + i sin(1080°/5) = cos(216°) + i sin(216°)
• cos(1440°/5) + i sin(1440°/5) = cos(288°) + i sin(288°)
If you wish, or are required to, you can go on to write these in terms of radicals by expanding cos(5x) and sin(5x) (where x = 72° so that 5x = 360°). For example,
cos(5x) = cos⁵(x) - 10 cos³(x) sin²(x) + 5 cos(x) sin⁴(x)
cos(5x) = cos⁵(x) - 10 cos³(x) (1 - cos²(x)) + 5 cos(x) (1 - cos²(x))²
cos(5x) = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)
which follows from the expansion
(cos(x) + i sin(x))⁵ = cos(5x) + i sin(5x)
due to DeMoivre's theorem and equating the real parts. Then cos(5x) = 1, and you can try to solve for cos(x) :
1 = 16 cos⁵(x) - 20 cos³(x) + 5 cos(x)
Actually, it would be easier to find sin(x) first, since sin(5x) = 0. The expansion in terms of sin(x) will look quite similar to the one shown here.

Lucy did 8 laps of an 800m derek did 12 laps of a 1.5km track on his bike who went further and by how munch
Answer:
Derek; by 11600 m.
Step-by-step explanation:
Convert 1.5km into m.
1.5 is 1500m.
1500 * 12 = 18000 m
8 * 800 <= Lucy
6400 m <= Lucy's distance
18000-6400=11600m
Based on the information, Derek went further by 11600m.
Lucy did 8 laps of an 800m. The total distance will be:
= 8 × 800m
= 6400m
Derek did 12 laps of a 1.5km track. The total distance will be:
= 12 × 1500m
= 18000m
Therefore, the difference will be:
= 18000m - 6400m
= 11600m
