Let f(x) = y

y = 2^x

x = 2^y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.

Answer: 51,440

Step-by-step explanation:

If a Veterinary tech earns 32,490 and a Barista earns 19,630

You're gonna create the equation ( 32,490 x 4 ) and get 129,960. Then your gonna subtract ( 19,630 x 4 ) from 129,960  and get around 51,440.

Also, you get the 4 from the number of years he works, which is 4.

This is because it’s asking for double of 16

Answer:

First, we find how many red beads there are:

2 + 1 + 3 = 6

12 - 6 = 6

Red beads = 6

Now we add the red beads and the purple beads:

Purple beads = 3

Red beads = 6

3 + 6 = 9

9/12 = 3/4

Answer:

split it into two shapes

Step-by-step explanation:

you will get a rectangle and triangle, evaluate areas.

Answer:

84m

Step-by-step explanation:

First split the shape up. There can be rectangle and then a triangle at the top.

Find the area of the rectangle first:

12 * 4 = 48.

Rectangle area 48m

Now find the area of the triangle at the top:

The base of the triangle is 12. The height would be 10-4 which gives you the height of 6.  So, 12 * 6 divided by 2 would give you the area of the triangle.

12 * 6 = 72, 72/2 = 36

Triangle Area 36m

Now add the two areas up: 48 + 36 = 84

So the area of the polygon is 84m

The probability that a exactly one chocolate contains nuts is 3/16 and probability that at least one chocolate contains nuts is 0.339.

Probability is calculated by dividing the number of possible outcomes by the total number of possible outcomes. Probability and odds are two distinct concepts. Odds are calculated by dividing the probability of something happening by the probability of it not happening.

When you calculate probability, you are estimating the likelihood of something occurring and representing it with a precise number.

The probability that a exactly one chocolate contains nuts

No of total chocolates = 16 chocolates

No of chocolates contain nuts = 3

The probability that a exactly one chocolate contains nuts = 3/16

Probability that  at least one chocolate contains nuts is

P(at least one contains nut) = 1 – P(given contains no nuts )^n

P(at least one contains nut) = 1 – (0.8125)^2

P(at least one contains nut) = 0.339

Probability that  at least one chocolate contains nuts = 0.339

Step-by-step explanation:

Hey!

This is a direct variation problem:

Direct variation describes a simple relationship between two variables . We say y varies directly with x.

y=kx, where k is the constant of variation or constant of proportionality.

==================================================================

We can substitute x and y in the given equation.

40=k20

Divide by 20 on both sides.

40/20=k

k=2

Substitute k in the Direct variation Equation:

y = 2x

Answer:

x = 12

m(QS) = 52°

m(PD) = 152°

Step-by-step explanation:

Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)

Thus:

m<R = ½[m(PD) - m(QS)]

50° = ½[(12x + 8) - (4x + 4)] => substitution

Solve for x

Multiply both sides by 2

2*50 = (12x + 8) - (4x + 4)

100 = (12x + 8) - (4x + 4)

100 = 12x + 8 - 4x - 4 (distributive property)

Add like terms

100 = 8x + 4

100 - 4 = 8x

96 = 8x

96/8 = x

12 = x

x = 12

✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°

✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°

We want to find the missing measures for the given square.

We know that squares have the same length in all of their 4 sides, with that in mind we can see that:

TS = TU = UV = SV = 15

Then we can already complete:

VU = 15

Now we need the two diagonals, SU and TV.

The diagonal for a square of side length s is:

diagonal = (√2)s

Then the diagonals for our square are:

TV = SU = (√2)*15 = 21.2

And SW is half of the diagonal, so we have:

SW = 21.2/2 = 10.6

45 + 3x = 180 subtract 45 from both sides

3x = 135 divide both sides by 3

x = 45 and to find angle UVW replace x with 45
