What is the value of x?

Enter your answer in the box.

Answer:

Growth

Step-by-step explanation:

Given

[tex]\frac{2}{3}(2.5)^x[/tex]

Required

Growth or decay

The general form is:

[tex]y = ab^x[/tex]

Such that:

[tex]b = rate[/tex]

For b, we have the following conditions:

[tex]b > 1[/tex] ----- Growth

[tex]0<b <1[/tex] --- Decay

[tex]b = 1[/tex] ---- None

Compare [tex]\frac{2}{3}(2.5)^x[/tex] to [tex]y = ab^x[/tex]

[tex]b = 2.5[/tex]

Because 2.5 > 1, then the first condition applies (growth)

Answer:

It will take $ 989.59 in Canadian funds to buy $ 800.

Step-by-step explanation:

If one Canadian dollar is equivalent to US $ 0.8150, in order to determine how much money is needed in Canadian funds to buy US $ 800.00 the following calculation must be performed:

0.8150 = 1

800 = X

(800 x 1) / 0.8150 = X

800 / 0.8150 = X

981.59 = X

Therefore, it will take $ 989.59 in Canadian funds to buy $ 800.

Answer:

(x,y)= ( 5 over 273, - 265 over 273)

Step-by-step explanation:

After solving the obtained equation with the elimination method the obtained value of x and y will be 2 and 1 respectively.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that,

8x-5y=11  ------ (1)

4x-3y=5 --------- (2)

In order to solve the above equation with the elimination method, we have to apply the multiplicative distribution law as,

Multiply by 2 in equation 2

2(4x-3y=5)

8x- 6y = 10  ----- (3)

Subtract equation 3 from equation 1,

(8x- 6y)-(8x-5y) = 10 - 11

8x-8x-6y+5y = -1

-y = -1

y=1

Substitute the value of y in any of the equations 1  to get the value of x

8x-5y=11

8x-5(1)=11

8x-5=11

8x=16

x=2

Thus, after solving the obtained equation with the elimination method the obtained value of x and y will be 2 and 1 respectively.

Answer:

C: The speed increases from A to F

Step-by-step explanation:

Check each node A to F including A and F.

B is higher than A, C is higher than B, ...

This is true for all of them, so it is increasing.

The speed of the car is increasing in the time interval from point A to point F. Option C is correct.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

The graph depicts the relationship between the x and y axes through the use of curves.

Here,
The graph shows the speed and time relation of the car,
Where,
The speed of the car is increasing from A to F,
The speed of the car is decreasing from F to G,
The speed of the car is increasing from G to H,
The speed of the car is decreasing from H to K,

Thus, the car's speed increases over the time span from point A to point F. Option C is the right answer.

Answer:

where the graph?

Step-by-step explanation:

Answer: The minimum is -4.

Step-by-step explanation:

The minimum of a function:

y = f(x)

will be the smallest value of y that the function gives.

such that, if the minimum is y = m

m ≤ f(x)   ∀ x

In this case, we can see that the smallest value of y is:

y = -4

Then the minimum of the sinusoidal function is -4.

One of the two basic types of animal locomotion: powered flight, actual flight, or gliding. Real wings are only found in most bird species, most insect orders, and bats.

A category listing is a list of various product categories, such as children's clothing, women's clothing, and men's clothing. Any form of a category can be simply created

Soaring and gravitational gliding are two distinct types of gliding flight.

In controlled gravitational gliding, a creature propels itself in a precise direction after delaying its descent and relying on the wind for horizontal motion (parachuting).

Adaptations for guided gliding are primarily made to increase glide ratio (the amount of horizontal distance covered per unit descent)

Therefore, powered flight or true flight are the two basic categories of animal locomotion.

Answer:

The Pooled Standard Deviation for these data sets is 1.09

Step-by-step explanation:  

Given that;

Standard Deviation 1 = 1.11

Standard Deviation 2 = 0.99

Standard Deviation 3 = 1.15

pooled standard deviation is given as;

[tex]S_{pooled}[/tex] = (n1 - 1 )s1² + ..... + ( nk - 1 )sk² / n1 + ..... + nk - 1

where n1, n2....., nk are the sample sizes of k groups and s1, s2, ....., sk are the standard deviations of k groups respectively

so for the 3 groups;

[tex]S_{pooled}[/tex]² =   (n1 - 1 )s1² + (n2 - 1 )s2² + ( n3 - 1)s3² / n1 + n2 + n3 - 3

we substitute

[tex]S_{pooled}[/tex]² =   (5 - 1 )1.11² + (5 - 1 )0.99 ² + ( 5 - 1)1.15² / 5 + 5 + 5 - 3

[tex]S_{pooled}[/tex]² =   (4.9284 + 3.9204 + 5.29) / 12

[tex]S_{pooled}[/tex]² =   14.1388 / 12

[tex]S_{pooled}[/tex]² =   1.1782

[tex]S_{pooled}[/tex] = √1.1782

[tex]S_{pooled}[/tex] = 1.08544 ≈ 1.09

Therefore, The Pooled Standard Deviation for these data sets is 1.09
