Answer:

-4 ± 2*sqrt(3)

Step-by-step explanation:

Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)

Answer:

1...ut

2..s

Step-by-step explanation:

you can see that the trapezium ABCD is talented than you are St trapezium so then from the ABCD trapezium Appa what then you can see a De is parallel to you are and ab is parallel to AC and DC is parallel parallel to T s and a De is parallel to ur

Answer:

1. UT

2. S

Step-by-step explanation:

1. parallel sides of the first trapezoid are DC and AB, the last being the longest

so the answer is

UT, which is shorter base

2. B is the right angle

so S is the one on the second trapezoid

Answer:

A) 70.5

Step-by-step explanation:

cos x = adjacent side/ hypotenuse

cos x = 10/ 30

cos x = 0.3

cos 70 = 0.3420

cos 71 = 0.3256

x = 70.5

Answer:

60ft^2

Step-by-step explanation:

60% of 10 is 6 and LxW is 10x6 so the area is 60 feet

Answer:

A: 230 seconds longer.

Step-by-step explanation:

1 minute is 60 seconds.

4 minutes is 240 seconds.

240-10=230

Answer:

the answer is 47

Step-by-step explanation:

you have to look at the y as 7 plug the 7 in the parentheses on the left side of the minus sign and you get 63. Now look at the 4x. X is now replaced with 4. 4 times 4 is 16. 63 minus 16 is 47.

Answer:

The answer is 15

Step-by-step explanation:

The answer is 15 because I used the order of operations. So, first I calculated the paranthesis. Then I multiplied left and right and I got 15.

Answer:

31.4 trillion decimal places but no one really knows how many decimal places there are. 31.4 trillion decimal places is a world record set by google

Step-by-step explanation:

Answer:

`31.4 trillion decimal places.

Explanation:

As far as we know Google found out that there is about 31.4 trillion decimal places which is rounded to 3.14. Google is not 100% accurate though, Pi is a mathematical number that never ends so we just use what we know which is 3.14. Pi is an ideal that in numerical terms can be approached, but never reached. In order to calculate Pi simply involves taking any circle and dividing its circumference by its diameter. William Jones is the "founder" of Pi in 1706. Jones was a British little-known mathematics teacher, Jones was the first person to use a symbol to represent the platonic concept of Pi.

Answer:

Step-by-step explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.

Answer:

1  5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1  5/9. Hope this helps!

Answer:

Answer:

(- 6, 10 ) and (- 1, 5 )

Step-by-step explanation:

Given the 2 equations

y = x² + 6x + 10 → (1)

y = - x + 4 → (2)

Substitute y =  x² + 6x + 10 into (2)

x² + 6x + 10 = - x + 4 ( subtract - x + 4 from both sides )

x² + 7x + 6 = 0 ← in standard form

(x + 1)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 6 = 0 ⇒ x = - 6

Equate these values into (2) for corresponding values of y

x = - 1 : y = - (- 1) + 4 = 1 + 4 = 5 ⇒ (- 1, 5 )

x = - 6 : y = - (- 6) + 4 = 6 + 4 = 10 ⇒ (- 6, 10 )

Answer:

saa.

Step-by-step explanation:

if you look at where the triangles connect, you will see they share an angle. that makes those two congruent. then yousee the SAA thrm. you go side (the line through one side) then the angle (the one that the two triangles share) then angle (the two marked congruent angles)

Answer:

You can refer the diagram I have solved.

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours

Step-by-step explanation:

All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.

Part 1: Garden Snail

= [tex]\frac{2,800}{0.029}[/tex]

≈ 96,551.7

Part 2: North American X-15

= [tex]\frac{2,800}{4,520}[/tex]

≈ 0.6

These are the answer!

Hope this helps! :)

Step-by-step explanation:

MORE MEMBERS PREFER A BEACH VACATION AND SKI VACATION THAN AN ADVENTURE VACATION

Answer: B

Step-by-step explanation:

A compound event is the combination of two or more events. Letter b explains how you roll a dice 4 times. The rest of the letters are only talking about one event. letter b shows more than 1. So the answer is B. In general the answer for compound events have to be a event that includes something done more than once

Answer: It represents the y intercept of f(x). ... f(0) represents the ordinate of the point where the function intersects the y axis. This is the y intercept of the function.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Two parallel lines will have the same slope. The slopes of parallel lines have to be equal. The y-intercepts of those two lines have to be different, otherwise they would be the same line. The x-intercepts of the parallel lines would also be different.

i just took the quiz

The required range of the function is 37.75 ≤ y ≤ 40. Option D is correct.

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining.

x =   0      0.5      1       1.5  
y = 40    39.25   38    37.75    

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Since the range of the function is the value of Y, so the range according to the y column of the table is all real numbers such that 37.75 ≤ y ≤ 40

Thus, the required range of the function is 37.75 ≤ y ≤ 40. Option D is correct.
