Will it be possible to climb a 950-foot rock formation within Jeremy’s time constraint? Explain why or why not.

Answer:

14n+4m

Step-by-step explanation:

Hey there!

“Simplify 2(7n + 5m – 3m)”

2(7n + 5m – 3m)

FIRST you have to DISTRIBUTE

2(7n) + 2(5m) + 2(–3m)

2(7n) = 14n

2(5m) = 10m

2(–3m) = –6m

14n + 10m – 6m

SECOND COMBINE your LIKE TERMS

(14n) + (10m – 6m)

(10m – 6m) = 4m ⬅️ FRONT number

(14n) = 14n ⬅️ BACK number

Answer: 4m + 14n ☑️

Good luck on your assignment and enjoy your day!

Answer:

They are both equivalent.

Step-by-step explanation:

It is the same except there is just a 0 added to the back to 0.270. If it was 0.207, then 0.27 would have been bigger, but a zero of the back of a decimal wont affect it at all.

As 'zero' to the rightmost side after the decimal place has no value to it 0.27 and 0.270 are equivalent decimal numbers.

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

We know 'zero' at the rightmost side after the decimal place has no value to it.

So, The numbers 0.270 and 0.27 are equivalent as 0.270 can be written 0.27.

Therefore the decimal numbers 0.27 and 0.270 are equivalent.

Answer:

14

Step-by-step explanation:

10+4=14

Answer: 14

Step-by-step explanation: 4 + 10 = 14 because , THE 10 is UP the 4 ADDS up so since it’s 4 +10 it would be 14. Cause you add 4 UP and equals 14.

There are essentially two ways that I know to solve this.

One is to guess.

The other is to find the prime factors of 96. For an integer to be a perfect square, each prime factor has to occur an even number of time. Therefore k would need to be the product of whatever primes occur in 96 an odd number of times.

Given that 9+6 is divisible by 3, we know that 96 is divisible by 3. Doing the division, we find that 96 = 3 * 32.

The prime factor 3 only occurs once. Therefore k must be a multiple of 3.

32 is 2 raised to the 5th power. This is an odd number of 2’s. We need one more. Therefore k must be a multiple of 2.

Therefore the smaller possible value of k is 6.

96 * 6 is a perfect square. It is the same as 64 * 9, or 24 * 24.

Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are  parallel, making two angles congruent and the triangles therefore similar.

Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height

Answer: Choice C) [tex]4 \le t \le 8[/tex]

======================================================

Explanation:

The point (4,5) is on the blue curve, and so is (8,9)

Draw a straight line through these points. This line has positive slope because it moves upward as we move from left to right, so there's a positive average rate of change from t = 4 to t = 8. Generally the curve goes upward as we move from t = 4 to t = 8.

Use the slope formula to compute the average rate of change if needed. It appears your professor doesn't want the actual numeric value, but just wants to know which interval corresponds to a positive average rate of change.

Answer:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

Answer/Step-by-step explanation:

Given, y = k√x

Let's find the following:

a. To find k, using the first pair given, (64, 16), plug in the values of the ordered pair into y = k√x

Thus:

16 = k√64

16 = k*8

Divide both sides by 8

16/8 = k

k = 2

b. To find F, substitute k = 2, and x = 100 into y = k√x

Thus:

y = 2√100

y = 2*10

y = 20

F = 20

c. To find x, substitute k = 2, and y = 10√2 into y = k√x.

Thus:

10√2 = 2√x

Divide both sides by 2

(10√2)/2 = √x

5√2 = √x

Square both sides

x = (5√2)²

x = 25*2

x = 50

Answer:

Step-by-step explanation:

The perimeter is half the circumference (C)  of the circle plus the diameter.

[tex]\frac{1}{2}[/tex] C = [tex]\frac{1}{2}[/tex] πd ( d is the diameter )

      = 0.5 × π × 3 = 1.5π

Thus

perimeter = 1.5π + 3 ≈ 7.71 ft ( to the nearest hundredth )

Answer:

Speed of train from station M = 85 miles per hour

Speed of train from station N = 90miles per hour

Step-by-step explanation:

Given that the distance between two points M and N is 380 miles

Suppose the speed of train M is x

So, the speed of train N is 5 + x

Formula to use:

distance = speed x time

For the train from point M

d = x * 2

d = 2x

For the train from point N

d = (5 + x) * 2

the above 2 distances plus 30 miles equals 380 miles

Equation:

2x + 2(x+5) + 30 = 380

2x + 2x + 10 + 30 = 380

4x + 40 = 380

4x = 380 - 40

4x = 340

x = 340/4

x = 85 mph for train M

Now put the value in the second train's speed

x + 5

85 + 5

= 90 mph for train N

Multiplying the first equation by 1 and the second equation by 5 to eliminate the y variable .

x= 0.3

y= -1.9

Step-by-step explanation:

8.3x + 5y = -7  ----------i

- 7x + y = -4 -----------ii

Multiply the first equation by 1 and the second equation by 5 to eliminate the y variable as below;

[8.3x + 5y = -7 ]1

[- 7x + y = -4]5

8.3x + 5y = -7

-35 x + 5y = -20

perform subtraction to eliminate y as

8.3x --35x = -7--20

43.3 x = 13

x= 13/43.3

x= 0.3

Using equation ii ;

-7x + y = -4

-7 * 13/43.3 + y = -4

-91/43.3 + y = -4

y= -4 + 91/43.3

y= -4 + 2.1

y= -1.9

Answer:

The middle terms are 80 and 4.

Step-by-step explanation:

Given the proportion:

5 : 80 :: 4 :64

To find:

The extreme and middle terms of the given proportion.

Solution:

The given statement is in proportion if and only if the product of extremes i.e. the numbers at both the ends is equal to the product of middle numbers.

OR

First number [tex]\times[/tex] Fourth number = Second number [tex]\times[/tex] Third number

First of all, let us check the two products.

5 [tex]\times[/tex] 64 = 320

And the second product:

80 [tex]\times[/tex] 4 = 320

The product is same therefore, the given numbers are in proportion.

The extreme terms are the first and the fourth numbers.

i.e. The extremes are 5 and 64.

The middle terms are 80 and 4.

Answer:

Step-by-step explanation:

To find the relative maximum of a function the double derivative should be less than zero at the stationary point. For that we need to find the stationary value/values of the function so here goes,

[tex]f(x)=-x^3+6x^2-9x-1\\f'(x)=-3x^2+12x-9\\\\For\ stationary\ point\ f'(x)\ equals\ zero\\\\0=-3x^2+12x-9\\3x^2-12x+9=0\\x^2-4x+3=0\\\\x^2-3x-x+3=0\\x(x-3)-1(x-3)=0\\(x-3)(x-1)=0\\x=3\ ,\ x=1[/tex]

Now since we have two values of x at which the function is stationary we need to test them both for that we need to take the double derivative so here goes,

[tex]f'(x)=-3x^2+12x-9\\f''(x)=-6x+12\\now\ put\ x = 1\\f''(1)=-6(1)+12\\f''(1)=-6+12=6\\since\ f''(1)>0[/tex]

The point x = 1 is a relative minimum

But we need the relative maximum so lets try out x = 3

[tex]f''(x)=-6x+12\\f''(3)=-6(3)+12\\f''(3)=-18+12=-6[/tex]

[tex]since\ f''(3)<0[/tex]

The point x = 3 is the relative maximum because for relative maximum the double derivative should be negative or less than 0 in this case its true so the last option is your answer

Answer:

Let's define the variables:

x = number of Cherrie pounds you buy

y = number of Grape pounds you buy.

The total cost of buying that will be:

x*$4 + y*$2.50

And this must be no more than $15, then we have the inequality:

x*$4 + y*$2.50 ≤ $15

And we also know that you need at least 5 pounds in total, then we will have:

x + y ≥ 5

We have the set of inequalities:

x + y ≥ 5

x*$4 + y*$2.50 ≤ $15

To graph them, a easy way is to write them as lines, and just graph the lines:

y ≥ 5 - x

y  ≤ ($15 - x*$4)/$2.50

in the first inequality, we have the symbol ≥, this means that we will have a solid line and we must shade above the line.

In the second inequality, we have the symbol ≤, this means that we will have a solid line and we must shade below the line.

And we also must include the conditions:

x ≥ 0

y ≥ 0

Because you can only buy positive numbers of fruit.

This will restrict us to the first quadrant only

Then the graph will be the one shown below.

Where the solutions are the ones in the double shaded region in the first quadrant.

The inequalities that represent the given data are [tex]\rm y \leq \dfrac{15-4x}{2.5}[/tex] and [tex]\rm y\geq 5-x[/tex] and the graph of these inequalities is attached below.

Given :

The following steps can be used in order to determine the graph showing the amount of each fruit you can buy:

Step 1 - Let 'x' be the total amount of cherries in pounds and let 'y' be the total amount of grapes in pounds.

Step 2 - The inequality that represents the total amount of fruits you can buy is given below:

[tex]\rm 4x+2.5y\leq 15[/tex]

[tex]\rm y \leq \dfrac{15-4x}{2.5}[/tex]

Step 3 - The inequality that represents the total amount of fruits you need to buy:

[tex]\rm x+y\geq 5[/tex]

[tex]\rm y\geq 5-x[/tex]

Step 4 - The graph that represents the inequalities evaluated in the above steps is attached below.
