Compute: 5 ∙ (2 + 3i)

Mathematics
1 answer:
dimulka [17.4K]3 years ago
4 0

Answer:

It will be equal to 40

Step-by-step explanation:

We have to compute 5\times (2+3!)

Let first find 3 !

For this we have to use factorial concept

So 3! will be equal to 3! = 3×2×1 = 6

Now According to 6+2 = 8

And now after solving bracket we have to multiply with 5

So 5×8 = 40

So after computation 5\times (2+3!)=40

So the final answer will be 40

Write an equation in slope-intercept form of the line that passes through (7, 2) and (2, 12)
Anika [276]

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope, b is the y-intercept (when x=0).

the slope is the ratio y/x indicating how much y changes, when x changes for a certain amount of units when going from one point to another.

going from (7, 2) to (2, 12) :

x changes by -5 (from 7 to 2), y changes by +10 (from 2 to 12).

so, the slope is 10/-5 = -2

therefore, we have already

y = -2x + b

we get b by using the coordinates of one of the points as x and y. e.g. (7, 2)

2 = -2×7 + b = -14 + b

16 = b

so, the full line equation is

y = -2x + 16

OLEGan [10]

Answer:

160 mL of fruit juice and 400 mL of sparkling water

Step-by-step explanation:

According to the statement we have that the ratio between fruit juice and sparkling water is 2/5.

Therefore, we could also say that:

200/500

with it could be done with 200 mL of fruit juice and 500 mL of sparkling water, so for 400 mL, how much would it be:

400 * 200/500 = 160

Therefore, the largest amount of the drink can be made with 160 mL of fruit juice and 400 mL of sparkling water.
