Are those supposed to be exponents? When multiplying exponents you add them together

b^3 * b^1 * b^4 * b^2
3 + 1 + 4 + 2 = 10

Answer: b^10

Jen has 3 bags of pears. If Jen gives the same number of pears to 4 friends. How many pears will each friend get

NISA [10]

Answer:

Each friend will get 3 pears.

Step-by-step explanation:

The question is incomplete and the complete question is:

Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pears will each friend get?

Now, to find the number of pears each of the 4 friends get:

So, as given:

Number of bags of pears = 3.

Number of pears each bag has = 5.

Thus:

Total number of pears = $3\times 5=15.$

Total number of friends = 4.

So, to get the number of pears each get we divide total number of pears by total number of friends:

$15\div 4$

$=3.75.$

Thus, if Jen gives same number pears to 4 friends 3 pears each will get.

Therefore, each friend will get 3 pears.

Find (f - g)(x)

Sidana [21]

Answer:

Step-by-step explanation:

We have the two functions:

$f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Hence, by substitution:

$=(3x^2-2x)-(9x^2-x+7)$

Distribute:

$=(3x^2-2x)+(-9x^2+x-7)$

Rearrange:

$=(3x^2-9x^2)+(-2x+x)+(-7)$

Combine like terms:

$=-6x^2-x-7$

Hence, our answer is A.

Complex numbers are used in electronics to describe the current in an electric circuit. Ohm's law relates the current in a circu

Marina CMI [18]

Answer:

E = 3072i - 5904ohms

Step-by-step explanation:

From ohms law recalled that E = IR given already

E = voltage (volts)

I = Current (amps)

R = resistance (ohms)

Therefore, by substitution

I = 16i and R = (2+4)ohms(32+66i)

= 6(32+66i) ohms

= (192+396i)ohms

E = (16i)×(192+396i)

E = 3072i + 5904i²

Recall that i² = -1 from complex number

E = 3072i +5904(-1)

E = 3072i - 5904ohms

Olin [163]

Answer:

19 degrees

Step-by-step explanation:

From the question given

The interior angles are x+12 and x - 3

Exterior angle is <IJK = 5x-6

Using the rule that states that the sum of interior angle of a triangle is equal to the exterior

<JHI + <HIJ = <IJK

x+12 + x-3 = 5x - 6

2x+9 = 5x -6

2x - 5x = -6-9

-3x = -15

x = -15/-3

x = 5

Get <IJK

Recall that <IJK = 5x - 6

<IJK = 5(5) - 6

<IJK = 25-6

<IJK = 19 degrees

Hence the measure of <IJK is 19 degrees
