Answer:

C) x = -2

Step-by-step explanation:

We just subtract, -19 + 7 = -2

Answer:

f(x)= -7 * 2^x

Step-by-step explanation:

The graph of the function goes through the point (0,−7) and (1,−14), so if f(x)= ab^x, then

f(0)= ab^0 = a

f(1)= ab^1 =ab

a=-7 and ab =-14 so,

b= -14/-7 = 2

thus the function is f(x)= -7 * 2^x

The exponential function y = -7b² is the required function.

An exponential function is a function which can be defined as y = aˣ,  Where 'x' is  a variable and 'a' is a constant.

From the given diagram,

The graph of the function go through the points (0,-7) and (1,-14),

And graph is exponential,

Let y= abˣ     (1)

y₀ = a and y₁ = ab

At x=0, y₀ = -7 ⇒a=-7

and ab=-14 ⇒ b= 2

Substitute the value of a and b in equation (1) ,

The function,

y = -7b²

The required function is y = -7b².

Answer:

The probability is [tex]P(X < 450 ) = 0.18703[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = \$ 490[/tex]

     The standard deviation is  [tex]\sigma = \$ 45[/tex]

Generally the probability that he/she earns less than $450 a week is mathematically represented as

        [tex]P(X < 450 ) = P(\frac{X - \mu }{\sigma} < \frac{450 - 490}{45} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

          [tex]P(X < 450 ) = P(Z < -0.8889 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -0.8889  is

         [tex]P(Z < -0.8889 ) = 0.18703[/tex]

=>     [tex]P(X < 450 ) = 0.18703[/tex]

Step-by-step explanation: PLEASE GIVEBRAINLIEST IT HELPS ALOT

Answer:

x=8

Step-by-step explanation:

Follow the order of operations to simplify the equation:

5(x-3) +2x=41  

Start by multiplying into the parenthesis: 5x-15+2x=41

Combine like terms: 5x+2x-15=41 then simplify: 7x-15=41

Add 15 to both sides: 7x=56

Divide both sides by 7 to get x by itself: x=8

Answer: the value of the diversity index D is Zero (0)

Step-by-step explanation:

Just as the meaning of diversity index is boldly explained in the question, it is the probability that randomly selected organism from a population are from a different species.

Now if the organisms are all from the same species in a population  then it is impossible to select two organisms from different species.

That is, we can never select two organisms that are not from the same species.

Hence, we cant fulfil or meet the definition of diversity index .

Therefore in this situation the value of our diversity index D will be exactly zero, D = 0.

Answer: 449.48

Step-by-step explanation:

The amount of money in the account after 18 years will be $449.5.  

Compound interest is the addition of interest to the principal sum of a loan or deposit. Mathematically -

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

where -

[A] = final amount

[P] = initial principal balance

[r] = interest rate

[n] = number of times interest applied per time period

[t] = number of time periods elapse

Given is that a person places $308 in an investment account earning an annual rate of 2.1%, compounded continuously.

We have the expression for compounding as -

V = P[tex]$e^{rt}[/tex]

V = 308 x [tex]$e^{(0.021)(18)}[/tex]

V = 308 x [tex]$e^{0.378}[/tex]

V = 449.5

Therefore, the amount of money in the account after 18 years will be $449.5.

Answer:

The equation of the line in the form Ax+By=C is [tex]\mathbf{ x+4y=-7}[/tex]

Step-by-step explanation:

We need to write an equation of line that have slope m= -1/4 and point(-7,0)

We would use slope-intercept form: [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

We are given slope m = -1/4 but we need to find y-intercept

Finding y-intercept

Using the slope m= -1/4 and point(-7,0) we can find y-intercept (b)

[tex]y=mx+b\\0=-\frac{1}{4}(-7)+b\\0= \frac{7}{4}+b\\b=-\frac{7}{4}[/tex]

Now finding the equation of line having slope m= -1/4 and y-intercept b= -7/4

[tex]y=mx+b\\y=-\frac{1}{4}x-\frac{7}{4}[/tex]

Now converting into form Ax+By=C :

[tex]y=-\frac{1}{4}x-\frac{7}{4}\\y=\frac{-x-7}{4}\\4y=-x-7\\x+4y=-7[/tex]

The equation of the line in the form Ax+By=C is [tex]\mathbf{ x+4y=-7}[/tex]

Answer:

[tex]Model = 80cm[/tex]

Step-by-step explanation:

Given

[tex]Length = 19.2\ m[/tex]

[tex]Scale=1:24[/tex]

Required

Determine the scale measurement in centimeters

The scale can be represented as: [tex]Model : Actual[/tex]

[tex]Scale = Model : Actual[/tex]

Substitute 19.2 for Actual Length

[tex]Scale = Model : 19.2\ m[/tex]

Represent as a fraction

[tex]Scale = \frac{Model}{19.2m}[/tex] --- (1)

Recall that:

[tex]Scale=1:24[/tex]

Represent as a fraction

[tex]Scale = \frac{1}{24}[/tex] --- (2)

Equate (1) & (2)

[tex]\frac{Model}{19.2m} = \frac{1}{24}[/tex]

Multiply through by 19.2m

[tex]Model = \frac{1}{24} * 19.2m[/tex]

[tex]Model = \frac{ 19.2m}{24}[/tex]

Convert to centimeter

[tex]Model = \frac{ 19.2 * 100cm}{24}[/tex]

[tex]Model = \frac{ 1920cm}{24}[/tex]

[tex]Model = 80cm[/tex]

Hence, the length of the scale model is 80 cm
