What’s 15x78+50-30???

Answer:

D

Step-by-step explanation:

add all sides together and multiply like a regular square and then divide by 2

i cannot help with all this but 16 would be 33 ft

This ODE is separable as

1/(6x) dy/dx = y √(3x ² - 1)

→   dy / y = 6x √(3x ² - 1) dx

Integrate both sides:

∫ dy / y = ∫ 6x √(3x ² - 1) dx

The left side is trivial. For the right side, substitute u = 3x ² - 1 and du = 6x dx :

∫ dy / y = ∫ √u du

ln|y | = u ³′² + C

(that is, u is raised to the 3/2 power)

ln|y | = (3x ² - 1)³′² + C

Solve for y by taking the exponential of both sides:

exp(ln|y |) = exp((3x ² - 1)³′² + C )

y = exp((3x ² - 1)³′²) × exp(C )

y = C exp((3x ² - 1)³′²)

which can be written as

y = C exp(√((3x ² - 1)³))

which makes the answer none of these; this solution can't be expressed as either option given in A or B.

How to simplify (-4)(-4)

-4×-4=16

Answer:

The answer is 16. Two negatives make a positive.

Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.

Answer:

A: The y-intercept of function m is less than that of function n.

Step-by-step explanation:

From the table, we see that when x = 0, m(x) = -6.

This means that the y-intercept of function m is -6.

For the function "n", we are told it passes through (-1, 0) and (0, 2)

We see that at the second coordinate, at x = 0, y = 2.

This means that the y-intercept of the n function is at 2.

Therefore,we conclude that the y-intercept of function m is less than that of function n.

Answer: F. 1/2

Step-by-step explanation:

If you add all the bows together, you get 10. The question is asking the probability of just 1 bow. This means you have a 1/10 chance. If you simply that, you end up with 1/2.

Answer:

10 is equal or less than (sign that opens up to the right with line underneath) j+5

Answer:

10 is less than j + 5

Step-by-step explanation:

because 10 lies between two consecutive perfect squares (in increasing order)...

Answer:

3t+2

Step-by-step explanation:

First, we focus on the part with the "t" variable. Then we subtract the values with variables which gets us 3t. Finally, we can't do anything with the +2, so our solution is 3t+2.

Answer:

41.834

Step-by-step explanation:

The complete length of the boston marathon is 26 miles

A mile is 1.609 kilometers

Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows

= 26 × 1.609

= 41.834

Hence the runner needs to run 41.834 kilometers

Answer:

[tex]Cost = 112.266[/tex] cent/km

Step-by-step explanation:

Given

[tex]Unit\ cost = R17.82/litre[/tex]

[tex]Rate = 6.3litre/100km[/tex]

Required

The fuel cost in [tex]cent\ per\ km[/tex]

This is calculated using:

[tex]Cost = Unit\ cost * Rate[/tex]

[tex]Cost = R17.82/litre * 6.3litre/100km[/tex]

[tex]Cost = R17.82 * 6.3/100km[/tex]

[tex]Cost = R1.12266/km[/tex]

Multiply by [tex]100[/tex] to get the cost in cents

[tex]Cost = 1.12266 * 100[/tex] cent/km

[tex]Cost = 112.266[/tex] cent/km

Answer:

12x⁶+24x⁵-180x⁴/ 30x³+240x²+450x

Step-by-step explanation:

(x-3)(x+5)=x²+2x-15

12x⁴(x²+2x-15)= 12x⁶+24x⁵-180x⁴

(x+3)(x+5)=x²+8x+15

30x(x²+8x+15)= 30x³+240x²+450x

Answer:

A = 94.6ft^2

Step-by-step explanation:

In order to be able to find the area of a trapezoid or any quadrilateral shape we need to use the equation:

A= a+b/2h

As we know we have the number base 7.7ft, base 14.3ft, and height of 8.6ft so then we take these numbers :

7.7 + 14.3/2 x 8.6 = 94.6

Answer:

0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year

Step-by-step explanation:

For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A San Francisco-based tech firm is able to keep 80% of its new employees after one year.

This means that [tex]p = 0.8[/tex]

Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year

This is P(X = 2) when n = 2. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{2,2}.(0.8)^{2}.(0.2)^{0} = 0.64[/tex]

0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
