Answer:

The shape of the pyramid does not provide information on population growth

Answer:

x² + y² = 169

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Given (12, 5 ) lies on the circumference , then the point will satisfy the equation.

Substitute (12, 5 ) into the equation

12² + 5² = r²

144 + 25 = r²

169 = r²

Then equation of circle is

x² + y² = 169

Step-by-step explanation:

it is a bit unclear to me how the cups are stacked on each other.

are we building a pyramid or is it really just one line of cups stacked into each other ? the equation suggests the latter. so, I will continue with that assumption.

then each additional cup really adds only the height of the rim to the total height of the cup tower.

so, we want to find out for what smallest x is the equation delivering as y value 32,400 or more.

32,400 = 2.4x + 13.6

let's get rid of the decimals by multiplying everything by 10.

324,000 = 24x + 136

323,864 = 24x

x = 323,864/24 = 13,494.33333...

so, we need 13,495 cups to reach its height (just rounding it to 13,494 would still leave a tiny gap, so we need the 13,495th cup - there is no way to reach the height exactly).

Answer:

Consistent and independent

Step-by-step explanation:

If two lines intersect, then the following things are true.

1. they have different slopes.

2. one solution.

3. The system of equation is consistent and independent

Answer:

-2/3

Step-by-step explanation:

First, distribute, -4(2x - 1) is -8x + 4. Next, do the opposite of the sign for the variable, since -8x can be written as - 8x, do the opposite sign, which is addition. -5 + 8 and -8 + 8. Add on both sides. Now you have 3x + 6 = 4. Then subtract 6 by 4. You'll get -2. The denominator is the number that has the variable. So now the equation will be 3x/3 = -2/3. You can turn -2/3 into a decimal, but it-s fine like that.

Answer:

It is a 5th-degree polynomial

Step-by-step explanation:

Looking at the expression, we can see that x⁵ is the term with the highest degree, so we call the expression a 5th-degree polynomial.

The river will not reach a level of 7 ft. after 5 hours.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the height of the water level after x hours.

Since the  river is 1 ft below its average water level and  begins to rise by a constant rate of 1.5 ft per hour. Hence:

b = -1, m = 1.5. The equation becomes:

y = 1.5x - 1

To reach a level of 7 ft. That is y = 7:

7 = 1.5x - 1

1.5x = 8

x = 5.3 hours

Answer: 40

Step-by-step explanation:

The angles in a triangle are equal to 180

We can use this equation to find x

180 = 20 + 3x + x

Then we solve

160 = 4x

x = 40

Answer:

180 = 20 + 3x + x

X = 40

Step-by-step explanation:

180 = 20 + 3x + x

Combine like terms

180 = 20 + 4x

Subtract 20 on both sides

160 = 4x

Divide both sides by 4

40 = x

Answer: 100 feet

Step-by-step explanation: Circumference is found using the formula C = 2πr. We can also use C = πd because diameter is two times the radius. Now that we know this, we can see that the diameter in your problem is 200 which means the radius is 200/2 or 100 feet. Hope this helps!

Answer:

A:Tina's. B: Gabby's

Step-by-step explanation:

Luckly the two people are using the same unit to measure both time (in weeks) and height (in inches), so no conversion needed.

At this point, let's start dealing with the questions.

A. They bought the plants at week 0.

For Tina, we calculate [tex]f(0) = 0+1.5 = 1.5[/tex]

For Gabby, we scout the table till we find week 0 and check the corrisponing value: it's (0; 1) Since 1 is smaller than 0, at start Tina plant was taller.

B. The easiest way would be to stare at Gabby's table for a bit, and notice that each increase is 2 more than the previous, and the progression starts at 1. We can write it as an equation as [tex]g(x) = 2x+1[/tex]. If you confront with Tina's growth, you can tell that Gabby's plant grows twice as fast - the slope is double. Else, you can see that even just after one week, Tina's plant will be 2.5 in tall, while Gabby's outgrew hers already. That's possible only if the plant is growing faster.

Answer:

-n

Step-by-step explanation:

The symbol √ means the principal square root.

The principal square root is always non-negative.

For example, even though the number 25 has two square roots, -5 and 5, since both (-5)² and (5)² equal 25, when you express the square root using the square root symbol, then √25 = 5, and not -5, since √25 means the principal square root of 25, and as a principal square root, it must be a non-negative number.

If n < 0, then you are dealing with negative numbers.

Once you square n to get n², n² is a positive number.

Then the square root of n², expressed with the square root symbol as √(n²) must be positive, so it equals -n.

Example:

Let n = -8.

Then n² = (-8)² = 64.

√(64) = 8

Compare 8 to -8. 8 is -(-8), just like we get -n.

Answer: -n

Answer:

  0.650

Step-by-step explanation:

The probability of rain on 4 or more days is the sum of the probabilities of rain on 4, 5, 6, and 7 of the days.

The probability of rain on 4 days is ...

  7C4×(0.57)^4×(1 -0.57)^(7-4) ≈ 0.29375

On 5 days, it is ...

  7C5×(0.57^5)(0.43^2) ≈ 0.23363

On 6 days, it is ...

  7C6×(0.57^6)(0.43^1) ≈ 0.10323

And on all 7 days, it is ...

  0.57^7 ≈ 0.01955

The sum of these probabilities is ...

  P(≥4) = 0.29375 +0.23363 +0.10323 +0.01955 = 0.65016

The probability of rain on 4 or more days is about 0.650.

The highest common factor of 9, 12, and 15 is 3.

To find the HCF (also called the GCF) of two or more numbers, we list their factors:

9: 1, 3, 9

12: 1, 2, 3, 4, 6, 12

15: 1, 3, 5, 15

Can you see that 3 is their GCF?
