What does it equal to and how

D) feet

A tree 1.5 x 10^3 is 1500 centimeters. That's about 300 inches, which would better be measured in feet.

You can use the fact that normally people use those measurements which are whole numbers or not elongated decimal number mostly and not much big numbers.

The most appropriate unit to measure the length of the tree out of the given options is

Option D:  feet

Normally people use those measurements which are whole numbers mostly and if not, then not too much long after decimal and not much big numbers.

A tree is measured suitably if we use feet. It is because the normal tree height is from few feet to few hundred feet.

If you measure tree height in centimetres, then as you can see in the question, the number before cm unit is quite big to handle by normal people.

If you measure in too big unit like kilometres, then the height would be expressed mostly like 0.some digits.

That's why we choose feet.

Since 1 cm = 0.0328 feet

thus, height of specified tree in feet would be

[tex]\rm 0.0328 \times 1.5 \times 10^{3} = 49.2 \: feet[/tex]

See the number before feet. Its not too big nor too small, and easy to remember and converse. That's why feet is appropriate.

Thus,

Answer:

19800

Step-by-step explanation

5 * 60 =300

5 hrs is 300 minutes

300 + 30 = 330

5hrs and 30 min is 330 min

330*60= 19800

5hrs and 30 min is 19800 sec

Answer:

See below.

Step-by-step explanation:

The slope of the line is (5-1) / (3 - -3)

= 4/6  = 2/3

Point slope form:

y - y1 = m(x - x1)

Plugging in m = 2/3 and the point (-3,1):-

y - 1 = 2/3(x + 3) (answer)

Slope-intercept form:-

y - 1 = 2/3(x + 3)

y = 2/3x + 2 + 1

y = 2/3x + 3 (answer)

Standard Form:-

y = 2/3x + 3

Multiply through by 3:-

3y = 2x + 9

-2x + 3y = 9  (answer).

The values of x and y that satisfy the system of equations are x = (1/3 ± i√(19))/1 and y = (±i√(19) + 2)/2.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

The equations 3x − 1 + 2y = 0 and 3x2 − y2 + 4 = 0

Now,

To find the corresponding values of y, we can plug these values of x into the expression for y that we found earlier:

[tex]y = -1/2(3x - 1). For x = (1/3 + i√(19))/1, we get: y = -1/2(3(1/3 + i√(19))/1 - 1) = -1/2(i√(19) - 2) = (i√(19) + 2)/2. For x = (1/3 - i√(19))/1, we get: y = -1/2(3(1/3 - i√(19))/1 - 1) = -1/2(-i√(19) - 2) = (-i√(19) + 2)/2.[/tex]

These are the values of y that satisfy the system of equations.

Therefore, by quadratic equations the answer will be x = (1/3 ± i√(19))/1 and y = (±i√(19) + 2)/2.

Answer:

C. After 6 minutes, Sam is 60 meters from the dock.

Step-by-step explanation:

Answer:

If x is an exponent in all those functions, then the function that grows the fastest is D, because it has the highest base 5 which is raised to x.

Step-by-step explanation:

The function  [tex]f(x) = 2\times5^x[/tex]  grows fastest. The correct answer is option D.

Given that the following functions:

[tex]f(x) = 5\times2^x[/tex]                      (1)

[tex]f(x) = 4\times3^x[/tex]                        (2)  

[tex]f(x) = 3\times4^x[/tex]                        (3)

[tex]f(x) = 2\times5^x[/tex]                       (4)

To determine which exponential function grows the fastest, compare the bases of the functions. The base of an exponential function determines how quickly it grows.

Let's compare the bases:

(1) The base is 2.

(2) The base is 3.

(3) The base is 4.

(4) The base is 5.

Since the base determines the rate of growth, conclude that  [tex]f(x) = 2\times5^x[/tex]  grows the fastest among the given options because 5 is the largest base.

In other words, as x increases, the function  [tex]f(x) = 2\times5^x[/tex]  will have the steepest increase in value compared to the other options.

Hence, the function  [tex]f(x) = 2\times5^x[/tex]  grows fastest.The correct answer is option D.

Answer:

Formula:

The general formula for the surface area (SA) of a prism is:

SA = 2B + Ph

Step-by-step explanation:

where:

B is the area of one base (since there are two identical bases, we multiply by 2).

P is the perimeter of the base (the total length of all sides of the base polygon).

h is the height of the prism (the distance between the two bases).

Steps to Find the Surface Area:

Identify the base shape and calculate its area:

Depending on the type of prism (triangular, rectangular, etc.), use the appropriate formula to find the area of one base.

Find the perimeter of the base:

Add up the lengths of all the sides of the base polygon.

Calculate the lateral surface area:

Multiply the perimeter of the base (P) by the height of the prism (h). This gives you the total area of all the lateral faces.

Sum the areas:

Add the area of two bases (2B) you calculated in step 1 and the lateral surface area from step 3. This will be the total surface area of the prism.

Tips:

Make sure you identify the correct height of the prism. It's the perpendicular distance between the two bases, not the length of a slanted lateral face.

If the lateral faces are not all the same shape (e.g., a truncated prism), you might need to calculate the area of each lateral face separately and add them all up.

By following these steps and using the formula, you can find the surface area of any prism!

Final answer:

The missing factors in the expression 3x³+12x²-9x are obtained by factoring out the common term 3x and then factoring the quadratic expression x²+4x-3. The final factorization is 3x(x+6)(x-1).

Explanation:

To find the missing factors in the expression 3x³+12x²-9x, we first factor out the common term, which is 3x.

So, the expression becomes 3x(x²+4x-3). Next, we need to find two numbers that multiply to -3 and add to 4. These numbers are 6 and -1, so we can further factor the quadratic as 3x(x+6)(x-1). In conclusion, the missing factors of the given expression are x+6 and x-1.

Answer:

a=4

Step-by-step explanation:

ax − 4 = 2y

We need to get the equation is slope intercept form  y= mx+b.

Lets solve for y

Divide each side by 2

a/2 x - 4/2 = 2y/2

a/2 x -2 = y

or y=a/2 x -2

The slope is a/2 and the y intercept is -2

We want a slope of 2  so a/2 =2

a/2=2

Multiply each side by 2

a/2 * 2 =2*2

a =4

Answer:

It would take 675.2809 days or 675.3 days

Step-by-step explanation:

first you simplify your equations if possible which you can here.

6.01×10^8=601,000,000        8.9×10^5=890,000

Then you are going to divide 601,000,000 by 890,000 or you cancel the zeros and then divide (your choice)

601,000,000/980,000

You can cancel out the zeros that both share so you'll be left with

60,100/89

then you divide and you get

675.2809

or you can round to the nearest tenth and you get

675.3

which makes no sense, our variable went poof, but that is a flag that this system has no solution, let's quickly solve both for "y" to put them in slope-intercept form,

so, notice, the slopes(m) are exactly the same for both, whilst the y-intercept differs, meaning both lines are parallel and therefore never touch each other, thus, no solution.

the untrue equation of -20 = 5, is another way to say, "no solution".

Answer:

7.25

Step-by-step explanation:

4 times 2 is 8 so then add another half and you will get 10 so multiply 2.5 times 2.5

Kellan should use 6.25 cups of water to make a batch of lemonade with 10 scoops of lemonade powder.

To determine how much water should be used, we can set up a proportion using the lemonade powder to water ratio. Since 4 scoops of lemonade powder are used for every 2.5 cups of water, we can write the proportion as:


4 scoops / 2.5 cups = 10 scoops / x cups

To solve for x, we can cross-multiply and divide:


4x = 10 * 2.5

4x = 25

x = 6.25 cups

Therefore, Kellan should use 6.25 cups of water to make a batch of lemonade with 10 scoops of lemonade powder.

Answer:

52+38

Step-by-step explanation:

An even number plus another even number results in an even sum. Examples such as 44 + 46 equaling 90 show this arithmetic principle.

The question pertains to the addition of two even numbers that equal 90. An even number is any integer that can be exactly divided by 2, which means its last digit will be 0, 2, 4, 6, or 8. When adding two even numbers, the result is always an even number.

For instance, if we consider the numbers 44 and 46, both are even:

This is just one example of even numbers adding up to 90. There are multiple pairs of even numbers that can sum up to 90, demonstrating the fundamental arithmetic principle that the sum of two even numbers is always even.
