Answers

Answer 1

Answer:

28cm

Step-by-step explanation:

ive done this question before

Answer 2

Answer:

28 cm

Step-by-step explanation:

This is the answer because:

Perimeter = L + W + L + W

Area =  L x W

1) Since the shape is a square, there has to be two of the same factors that multiply.

_ x _ = 49

2) We know 7 x 7 = 49, therefore, w just have to add 7 + 7 + 7 + 7 which equals 28 cm

Therefore, the answer is 28 cm

Hope this helps! :D

help find the equation of the tangent line please (calculus)

Answers

The tangent line to f(x) at x = c has slope equal to the derivative at c, or f'(c).

We have

f(x) = 3 - 2 x + 7 x²

so that

f'(x) = -2 + 14 x

The slope is 5 for

-2 + 14 x = 5   ==>   14 x = 7   ==>   x = 1/2

Now, f (1/2) = 15/4, so the tangent line has equation

y - 15/4 = 5 (x - 1/2)   ==>   y = 5 x + 5/4

C. 2:3, because two-thirds of the cats Billy saw were tigers
D. 1:3, because Billy saw 3 fewer tigers than lions at the zoo

Answers

Answer:

Step-by-step explanation:

The correct ratio is 1;3 so that eliminates B and C. The problem doesn't state anything about Billy seeing groups of tigers so D is the only logical answer.

20/3 = ?/6 what is the answer to the question mark

Answers

Answer:

40. 3*2 is equal to 6 so 20*2 equals 40

The value of the missing number in the equation is 40.

What is the value of the missing number?

Given the equation in the question:

20/3 = ?/6

Let x represent the missing number:
Hence:

20/3 = x/6

To solve for x, we cross-multiply and simplify:

20/3 = x/6

Cross multiplying, we get:

3 × x = 20 × 6

Multiply 3 and x:

3x = 20 × 6

Multiply 20 and 6:

3x = 120
Divide both sides by 3:

x = 120/3

x = 40

Therefore, the value of x is 40.

find X in the ratio 1:3 = 9:x​

Answers

Answer:

27

Step-by-step explanation:

9*3=27

since it's always 3 times the amount of the left side we would just multiply 9 by 3

The required value of x would be 27 in the given ratio 1:3 = 9:x​.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The ratio is given in the question as follows:

1:3 = 9:x​

We have to determine the value of x in the given ratio.

As per the question, we have

1:3 = 9:x​

⇒ 1/3 = 9/x

Apply the cross-multiplication,

⇒ x = (3) × (9)

Apply the multiplication operation, and we get

⇒ x = 27

Therefore, the required value of x would be 27.

Two Angles are Supplementary when they add up to 180 degrees. You didnt add a picture but choose the angles that create a straight line, kind of like if you were doing a puzzle.

The supplementary angle pairs are: angles 4 and 5

What are supplementary angles?

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. Which means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

We know that Two Angles are Supplementary when they add up to 180 degrees.

Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is resent. Suppose a voice packet can be transmitted a maximum of 8 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p, determine the probability mass function of the number of times a packet is transmitted.

Answers

Answer:

 The  probability mass function is

         [tex]F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }[/tex]

Step-by-step explanation:

From the question we are told that

   The maximum transmission time is  [tex]n  =  8[/tex]

Generally the number of times a packet is transmitted follows a binomial distribution given that the  the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p

Generally the probability mass function is mathematically represented as

          [tex]F(x) =  [ \left \ 8 } \atop {x}} \right. ] * p^x  *  q^{n - x }[/tex]

Here  x can take values x =  0 ,  1 , 2 , 3 , ... , 7
