Answer:

3√3+4

Step-by-step explanation:

Given the vectors u = <√3, -1> and v = <3, -4>

u · v = <√3, -1> *<3, -4>

u · v = 3√3 + (-1*-4)

u · v = 3√3+(4)

u · v = 3√3+4

Hence the dot product is 3√3+4

Find the value of x

-Dominant- [34]

Answer:

Step-by-step explanation:

we know that the sum of these two angles=180 degrees

5x/2 +125=180

5x/2=180-125=55

5x/2=55

5x=55*2

5x=110

x=110/5=22

x=22

An angle measures 10° less than the measure of its supplementary angle. What is the measure of each angle?

spin [16.1K]

Answer:

The two angles are 85 and 95 degrees

Step-by-step explanation:

Supplementary angles add to 180

Let x be one angle

The supplement is 10 less, ( x-10)

They add to 180

x+ ( x-10) = 180

2x -10 = 180

Add 10 to each side

2x-10+10 =180-10

2x= 190

Divide by 2

2x/2 =190/2

x=95

The other angle is 95-10 = 85

The two angles are 85 and 95 degrees

Write the exponential equation for this scenario. Mike buys a car for $45,000.00. The cars value depreciates (loses value) at a

gladu [14]

Answer:

$A=45000(0.82)^t$

Step-by-step explanation:

Given data

P= 45,000

rate= 18%

Recall the expression for the compound interest

$A=P(1+r)^t$

Since we are talking of depreciation

$A=P(1-r)^t$

Substitute

$A=45000(1-0.18)^t\\\\A=45000(0.82)^t$

Hence the exponential function is

$A=45000(0.82)^t$
