Answer:

Option C.

Step-by-step explanation:

We know that

f(t) = 1.5t + 50

represents the approximate population of trout in Sky Lake

And

g(t) = 0.1t^2 - 4t + 70

represents the approximate population of trout in Lake Cyan

The total trout population in the area is described as

f(t) + g(t)

f(t) + g(t) =  [1.5t + 50] + [0.1t^2 - 4t + 70]

f(t) + g(t) =  [1.5t + 50+ 0.1t^2 - 4t + 70]

f(t) + g(t) =  [0.1t^2 -2.5t + 120]

f(t) + g(t) =  0.1t^2 -2.5t + 120

Answer with explanation:

Consider two linear equation in two variable,

ax + by =c

p x +q y=r

The equations have an infinite number of solutions , means the two lines are Coincident, when it follows the following law

[tex]\frac{a}{p}= \frac{b}{q}= \frac{c}{r}[/tex]

Now, equation of two lines are

1. y= 6 x -b

→6 x -y -b=0

2. -3 x +y= -3

⇒-3 x+y+3=0

By the above law,that is law 1, the two lines will be coincident

[tex]\frac{6}{-3}=\frac{-1}{1}= \frac{-b}{3}\\\\2=1= \frac{b}{3}[/tex]

Which is not possible that is ,2≠1.

→→→Hence the two lines can never be coincident for any value of b.

Answer:

Monthly Expense = $270.83

Step-by-step explanation:

The semi-annual premium is paid twice a year so,

Automobile insurance premium for whole year = 650*2

= $1300

Monthly premium will be paid 12 times a year so,

Health insurance premium for whole year = 125*12 = $1500

Annual premium is only paid once a year.

So adding all the premiums will give us the total premiums for whole year.

Total amount of premium for a year = $1300+$1500+$450

= $3250

The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.

So monthly expense is:

= 3250/12

= $270.83 ..

To find the monthly expense, calculate the total annual premium for each insurance and divide by 12. The monthly expense is $187.5.

To find the monthly expense, we need to calculate the total annual premium for each insurance and divide it by 12 (since there are 12 months in a year).

For automobile insurance, the semiannual premium is $650, so the annual premium is $650 * 2 = $1300.

The monthly premium for health insurance is $125.

For life insurance, the annual premium is $450.

Now, let's calculate the total monthly expense: ($1300 + $125 + $450) / 12 = $187.5.

So, the monthly expense is $187.5.

e. logₐ(3x)₂ = 2 logₐ3 + logₐx

False.

f. logₐ(3x)₂ = 2 logₐ3 + 2 logₐx

Answer:

a. False

b. True

c. False

d. True

e. False

f. True

Step-by-step explanation:

By properties of logarithms:

a. False: ㏒ₐb-㏒ₐc ≠ (㏒ₐb / ㏒ₐc) does not exists that property

b. True: (㏒ₐb)-(㏒ₐc) = ㏒ₐ(b/c)  Logarithm of a Quotient

c. False: Does not exists the property:  ㏒ₐ(c+b) = ㏒ₐc + ㏒ₐb

so

㏒₄(5x+16) ≠ ㏒₄5x + ㏒₄16 but,  ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x  

because ㏒₄16 = 2.

d. True:  Logarithm of a Product: ㏒ₐ(c×b) = ㏒ₐc + ㏒ₐb

so

㏒₄(16×5x) = ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x

e. False: Logarithm of a Power: ㏒ₐ(c×b)ⁿ = n ㏒ₐ(c×b) = n (㏒ₐc + ㏒ₐb) = n ㏒ₐc + n ㏒ₐb

so

㏒ₐ(3x)² ≠ 2 ㏒ₐ3 + ㏒ₐx

f. Correct use of property in point e.

The given compound inequality doesn't have any solutions because it creates a contradictory situation where x needs to be both greater than 9 and less than 0 at the same time, which is not possible.

The given compound inequality is −33 > −3x − 6 ≥ −6. To find the equivalent form, let's solve it step by step.

First, add 6 to all sides, resulting in -27 > -3x > 0.

Then, divide by -3. Remember that when dividing by a negative number, the direction of the inequality changes. So, we get 9 < x < 0.

This indicates that x is greater than 9 but x also needs to be less than 0. This, however, is a contradictory situation because a number cannot be both greater than 9 and less than 0 at the same time. So, there are no solutions for this inequality.

An equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.

To find an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6, we can break it down into two separate inequalities:

−33 > −3x − 6

−3x − 6 ≥ −6

To simplify the first inequality, we can add 6 to both sides: −27 > −3x. Then, we can divide both sides by -3, remembering to flip the inequality sign since we are dividing by a negative number: x > 9.5.

To simplify the second inequality, we can add 6 to both sides: −3x ≥ 0. Then, we can divide both sides by -3, remembering to flip the inequality sign: x ≤ 0.

Therefore, an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.

Answer:The age of daughter is 12 years  and age of son is 24 years

Step-by-step explanation:

Given :

Present age of father = 52 years

Let the present age of daughter be x

So according to the question son's age is twice that of daughter's

So present age of son =2x

Now after 4 years the sum of their ages = 100

i.e. x+4 + 2x+4 + 52 +4 =100

3x+ 64 = 100

Subtracting both sides by 64 we get

3x + 64 - 64=100 -64

3x = 36

Dividing LHS and RHS by 3 we get

x=12

i.e. Present age of daughter  = x = 12 years

Present age of son = 2x = 2× 12= 24 years

In order to solve these types of problems, you should first subtract the difference of the two pieces. You get 4. Divide by 2 (two pieces) and there are 2 and 2. Add the 8 back to one of them, and you get 10 ad 2.

Let

[tex]P(n):\ 1+2+\ldots+n = \dfrac{n(n+1)}{2}[/tex]

In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:

[tex]P(1):\ 1 = \dfrac{1\cdot 2}{2}=1[/tex]

So, the base case is ok. Now, we need to assume [tex]P(n)[/tex] and prove [tex]P(n+1)[/tex].

[tex]P(n+1)[/tex] states that

[tex]P(n+1):\ 1+2+\ldots+n+(n+1) = \dfrac{(n+1)(n+2)}{2}=\dfrac{n^2+3n+2}{2}[/tex]

Since we're assuming [tex]P(n)[/tex], we can substitute the sum of the first n terms with their expression:

[tex]\underbrace{1+2+\ldots+n}_{P(n)}+n+1 = \dfrac{n(n+1)}{2}+n+1=\dfrac{n(n+1)+2n+2}{2}=\dfrac{n^2+3n+2}{2}[/tex]

Which terminates the proof, since we showed that

Average = -1°C

Step-by-step explanation:

The data recorded is;

6, -7, -5, 5, -8, 3 (in °C)

Average = [tex]\frac{6 - 7 - 5 + 5 - 8 + 3}{6}[/tex] = -1°C

Answer:

Average temperature listed will be (-1).

Step-by-step explanation:

As we know average of any given set of numbers is = [tex]\frac{\text{Sum of all the numbers}}{\text{Total numbers }}[/tex]

Now the given set of temperatures is 6, -7, -5, 5, -8, 3

Now Sum of all numbers = 6 + (-7) + (-5) + 5 + (-8) + 3

= (-6)

Total numbers = 6

The volume of the cylinder is [tex]\( 2160 \pi \)[/tex] units³.

To find the volume of the cylinder, we'll use the formula for the volume of a cylinder, which is given by:

[tex]\[ V = \pi r^2 h \][/tex]

Where:

- V is the volume of the cylinder,

- r is the radius of the cylinder, and

- h is the height of the cylinder.

Given:

- Height h = 15 units

- Radius r = 12 units

We'll substitute these values into the formula:

[tex]\[ V = \pi \times (12)^2 \times 15 \][/tex]

[tex]\[ V = \pi \times 144 \times 15 \][/tex]

[tex]\[ V = 2160 \pi \][/tex]

So, the volume of the cylinder is [tex]\( 2160 \pi \)[/tex] cubic units.

Answer:

Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points A(-3, 0) and B(-6, 5). Substitute:

[tex]m=\dfrac{5-0}{-6-(-3)}=\dfrac{5}{-3}=-\dfrac{5}{3}[/tex]

The line passes through the origin, therefore the y-intercept is equal to 0.

Therefore we have the equation:

[tex]y=-\dfrac{5}{3}x[/tex]

Convert to the standard form [tex]Ax+By=C[/tex]

[tex]y=-\dfrac{5}{3}x[/tex]         multiply both sides by 3

[tex]3y=-5x[/tex]                add 5x to both sides

[tex]5x+3y=0[/tex]

The equation of the line parallel to AB passing through the origin is 5x - 3y = 0.

The equation of the line that passes through the origin and is parallel to AB is 5x - 3y = 0.

To find the equation of a line parallel to AB passing through the origin, we first need to find the slope of AB, which is (5 - 0) / (-6 + 3) = 5 / -3 = -5/3.

Since the line passing through the origin and parallel to AB has the same slope, its equation will be of the form y = mx. Substituting the point (0, 0) into y = -5/3x gives us y = -5/3x, which simplifies to 5x - 3y = 0.
