A statement which correctly compares the two functions on the given interval [-1, 2] is: C. Both functions are increasing, but function g increases at a faster average rate.

First of all, we would determine the values of function g(x) on the given interval [-1, 2] as follows:

g(x) = -18(⅓)^x + 2

At x = -1, we have:

g(-1) = -18(⅓)^(-1) + 2

g(-1) = -52.

At x = 0, we have:

g(0) = -18(⅓)^(0) + 2

g(0) = -16.

At x = 1, we have:

g(1) = -18(⅓)^(1) + 2

g(1) = -4.

At x = 2, we have:

g(2) = -18(⅓)^(0) + 2

g(2) = 0.

By critically observing the values of each functions, we can logically deduce that both functions are increasing but function g(x) increases at a faster average rate because it started with a lower value and ended with a higher value.

Answer:

120%

Step-by-step explanation:

10.14 is more than all of 8.45.

8.45 is 100% of 8.45.

So 10.14 will be more than 100%.

10.14 ÷ 8.45 = 1.2

This is the decimal value.

To change to %, multiply by 100.

1.2 × 100 = 120

Did the math to find the solution earlier, got right xoxo :)

The value of w is 38400 when the value of c is 6 as per the concept of a proportional relationship.

Given:

We have to find the value of w at c = 6.

If c = 6, then the value of a becomes a = 48 times (6 divided by 3)

Therefore, the value of a can be evaluated as,

a = 48 x 6/3

a = 48 x 3

a = 144

To find the value of w, rearrange the value of 'a' in the multiple of 9.

For that, divide 144 by 9.

144/9 = 16.

Now, multiply 16 by 2400.

The final value of w = 2400 x 16

w = 38400

Answer:

Step-by-step explanation:

The friend solved

The value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

The current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms.

As we know,

V = IR

V = (3 + j2)(4 - j3)

[tex]\rm V=\left(3\cdot \:4-2\left(-3\right)\right)+\left(3\left(-3\right)+2\cdot \:4\right)j[/tex]

j² = -1 (complex part)

The rocket will take 2 seconds for the rocket to hit the ground.

We have,

To find the time it takes for the rocket to hit the ground, we need to determine when the height, h, becomes zero (since the ground is at height zero).

Given the equation for the height of the rocket at time t:

h = -4.9t² + 9.1t + 1.4, we can set h to zero and solve for t:

0 = -4.9t² + 9.1t + 1.4

This is a quadratic equation in the form of at² + bt + c = 0,

where a = -4.9, b = 9.1, and c = 1.4.

To solve for t, we can use the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

Substituting the values:

t = (-(9.1) ± √((9.1)² - 4(-4.9)(1.4))) / 2(-4.9)

t = (-9.1 ± √(82.81 + 27.44)) / (-9.8)

t = (-9.1 ± √110.25) / (-9.8)

Now, we have two possible solutions for t:

t₁ = (-9.1 + √110.25) / (-9.8)

t₂ = (-9.1 - √110.25) / (-9.8)

Calculating these values:

t₁ ≈ -0.143

t₂ ≈ 2

Since time cannot be negative, the only meaningful solution is t₂ ≈ 2 seconds.

Thus,

The rocket will take 2 seconds for the rocket to hit the ground.

The correct answer is option B which is we need ∠L ≅  ∠R to prove congruency.

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

According to the SAS theorem which means Side Angle Side, The angle which is included between the two sides must be congruent.

Here we are given that

KL = NR

JL = MR

Now in the figure, we can clearly see that the angle included between JL & KL is L & the angle included between NR & MR is R.

So for the triangles to be congruent by SAS, angle L must be congruent to angle R.

∠L=∠R

Therefore the correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.

Answer: option b

Step-by-step explanation:

Answer:

5√3

Step-by-step explanation:

An equilateral triangle is a triangle that has all same 3 measurements of 60°, and since all measurements are same, all sides are also equal too.

Hence, there'll be 3 sides that are 10 units. Since the base is divided into half, each will be 5 for base.

Then apply Pythagoras Theorem where states that:

[tex]\displaystyle{c=\sqrt{a^2+b^2}}[/tex]  or [tex]\displaystyle{c^2=a^2+b^2}[/tex]

where c is hypotenuse, a and b can be defined either adjacent or opposite.

We know that our adjacent is 5 units, opposite is h unit(s) and hypotenuse is 10 units. Apply the theorem:

[tex]\displaystyle{10^2=h^2+5^2}[/tex]

Solve the equation for h-term:

[tex]\displaystyle{100=h^2+25}\\\\\displaystyle{100-25=h^2}\\\\\displaystyle{75=h^2}\\\\\displaystyle{h=5\sqrt{3} }[/tex]

Therefore, the height or value of h is 5√3

Answer:

First Option

Step-by-step explanation:

First, we will find the equation for the total cost of the tickets.

Given x = Cost of 1 adult ticket

y = Cost of 1 Child ticket

Total Cost of tickets at $40:

2x + 4y = 40

To find which graph represent the cost of the tickets,

we can substitute x = 0 to find y and vice-versa.

If x = 0 ,

[tex]2(0) + 4y = 40\\4y = 40\\y = \frac{40}{4} \\= 10[/tex]

So when x = 0 , y = 10 which gives the coordinates (0,10).

Now if y = 0,

[tex]2x+4(0) = 40\\2x = 40\\x = \frac{40}{2} \\= 20[/tex]

So when y = 0 , x = 20 which gives the coordinates (20,0)

This shows that this particular line passes through these 2 points and therefore the answer is the first option.

Mary should pour around 3.7 liters or 226.08 in³ volume of water in the vase.

Given Information and Formula Used

Radius of the cylindrical vase, r = 3 inches

Height of the cylindrical vase, h = 8 inches

The formula for the volume, V of a cylinder is given as,

V = πr²h

Here, r is the radius of the cylinder and h is the height of the cylinder.

Calculating the Volume

Substituting the given values of r and h in the formula for the volume of cylinder, we get

Volume, V = π(3)²(8)

Using π = 3.14, we have,

V = 3.14(9)(8)

V = 226.08 cubic inches

Volume in Liters

Since, 1 Liter = 61.0237 cubic inches,

1 cubic inch = 1/61.0237 liters

⇒ 226.08 cubic inches = 226.08/61.0237 liters

⇒ 226.08 cubic inches ≈ 3.07 liters

Thus, Mary needs to pour approximately 3.07 liters volume of water in the vase.

The compound inequality which represents the number of ounces of clay is c≤4.5 or c≥12.

Given ELISA uses no more than 4.5 ounces of clay and to make a large vase, she uses at least 12 ounces of clay.

Let c denote the wide variety of oz of clay that Elisa makes use of to make one vase of both length.

The words "no more than" implies "much less than or equals to".

So, for a small vase c must be less than or equal to 4.5 ounce, which gives

c≤4.5       ...(1)

And to make a huge vase, she makes use of as a minimum 12 oz of clay.

The word "at least" implies "extra than or equals to"

So, for a large vase c must be more than or equal to 12 ounce, which gives

c≥12         ...(2)

By combining equations (1) and (2), we get
