Answer:

y = (4)(3)^x, with a = 4, b = 3

Step-by-step explanation:

y = ab^x

4 = ab^0 = a(1) = a

108 = 4b^3

108/4 = 27 = b^3

cube root of 27 = 3, so b = 3

Answer:

16

Step-by-step explanation:

So, we know it isn't D. We've narrowed it down to the top 3 answers now we would have to Divide 39 and 7 that would equal to 19.5. So, it could be A or B now. It says less 7 years, so we would know have to do this 39 - 7 = 32 32 / 2 = 16.

Therefore your answer is 16

Answer:

There is no graph

Step-by-step explanation:

One has to solve this using either substitution or elimination then...

x + y = 5

–2x + y = –4

x + y = 5

2x –y = 4

3x = 9

x = 3

y = 2

Solution (3 , 2)

42+8=50 inc

Step-by-step explanation:

It says that ty is shorter so you add 8 inches to get reese height

Answer:

50 inches tall

Step-by-step explanation:

R-8=42

r=reece height

the reason why you need to add is  becuase ty is shorter by 8 inches, so you need to add those 8 inches, if it said he was taller then you wouldve subtracted

∠ YZX ≈ 19.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinZ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{7.5}{22.3}[/tex] , then

∠ YZX = [tex]sin^{-1}[/tex] ([tex]\frac{7.5}{22.3}[/tex] ) ≈ 19.7° ( to 3 significant figures )

x=NEGATIVE 1/2, POSITIVE 2

Step-by-step explanation:

Just use math.waycom

The non-negative zero of the function f(x) is x = 2.

The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

here, we have,

For a given function f(x), the "zeros" of the function are the values of x such that:

f(x) = 0

In this case, we have the function:

f(x) = 6*x^2 - 9*x - 6

If we want to find the zeros of this function, we need to solve:

f(x) = 0 =  6*x^2 - 9*x - 6

To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:

0 = a*x^2 + b*x + c

The zeros are:

x = -b ±√b² - 4ac / 2a

In this case our equation is:

0 =  6*x^2 - 9*x - 6

then, in the above notation, we have:

a = 6

b = -9

c = -6

Replacing these in our general formula, we get:

x = 9±15 /12

Then we have two zeros:

x = (9 + 15)/12 = 24/12 = 2

x = (9 - 15)/12 = -6/12 = -1/2

But we want only the non-negative, so we can discard the second one.

Concluding, the non-negative zero of the function f(x) is x = 2.

Answer:

r = p(-b/a)

Step-by-step explanation:

Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.

Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.

So, p(x) = q(x)(ax + b) + r

Now, p(x) = r when q(x)(ax + b) = 0

since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a

⇒ p(x) = r when x = -b/a

So, r = p(-b/a)

So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)

Answer:

16.5 year

Step-by-step explanation:

Using, mean = sum/no. *of observations

Here,

=> 16.2 = (sum of ages of boys)/18

=> 16.2 x 18 = sum of ages of boys

=> 291.6 = sum of ages of boys

Similarly, sum of ages of girls = 27 x 16.7 = 450.9

Mean(total) = (sumof agesof boys + girls)/45

Mean = (291.6 + 450.9)/45 = 16.5

Answer:

The mean age of all 45 boys and girls is 16.5years

Step-by-step explanation:

Since the mean age of the 18 boys is 16.2years,

∴ Sum of their ages = 18 × 16.2

                                 = 291.6years

The mean age of the 27 girls is 16.7years

∴ Sum of their ages = 27 × 16.7

                                 = 450.9years

∴ Mean age of all 45 boys and girls = [tex]\frac{291.6 + 450.9}{45}[/tex] years

                                                           = [tex]\frac{742.5}{45}[/tex] years

                                                           = 16.5 years

∴ The mean age of all 45 boys and girls is 16.5 years.

$9.10 + 0.46 = 9.56

Answer:

Step-by-step explanation:

1 full container = 18 Liters.

The amount in the container = 7 2/3

The amount left to go is 18 - 7 2/3

Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3  If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3

17 - 5 = 12

3/3 - 2/3 = 1/3

So the answer is 12 1/3

Answer:

$8.72

Step-by-step explanation:

Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.

8 x (9/100) = tax

8 x 0.09 = 0.72

8+0.72 = $8.72

The fraction 9 / 8 can also be written as [1/8 + 8/8] , [2/8 + 7/8] , [3/8 + 6/8]

What is a fraction?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.

Given data ,

The number = 9 / 8

The number can be written as the sum of two different fractions as

a) 1/8 + 8/8 = (1+8)/8

                  = 9/8

b) 2/8 + 7/8 = (2+7)/8

                   = 9/8

c) 3/8 + 6/8 = (3+6)/8

                   = 9/8

Hence ,

The fraction 9 / 8 can also be written as [1/8 + 8/8] , [2/8 + 7/8] , [3/8 + 6/8]
