Answer:

63

Step-by-step explanation:

use tangent formula

[tex] \tan(40) = \frac{h}{75} [/tex]

Answer:

h ≈ 62.9 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )

75 × tan40° = h , then

h ≈ 62.9 ft ( to 1 dec. place )

Answer:

0.0078125

Step-by-step explanation:

Probability of tail, p = 0. 5

Probability of getting all tails from 7 tosses :

P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)

0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125

We could also use the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

n = 7 ; x = 7, p = 0.5,

P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125

Answer:

16,384

Step-by-step explanation:

The pattern is times 2

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384

The 14th term is 16384

The required 14th term of the given geometric sequence 2, 4, 8, is 16384.

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The geometric sequence is given in the question as:

2, 4, 8, ...

To determine the 14th term of the geometric sequence 2, 4, 8, you can use the formula for the nth term of a geometric sequence, which is [tex]a_n = a_1 \times r^{(n-1)}[/tex], where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, and r is the common ratio.

In this case, the first term is 2, the common ratio is 2, and the term you want to find is the 14th term, so you can plug these values into the formula to get:

[tex]a_{14} = 2 \times 2^{(14-1)}[/tex]

= 2 × 2¹³

= 2 × 8192

= 16384

Therefore, the 14th term of the geometric sequence is 16384.

Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.

Answer:

5.3

Step-by-step explanation:

a² + b² =² c²               the Pythagorean theorem

RQ² + RS² = QS²            Solve RS

6² + RS² = 8²

RS² = 64 -36

RS² = 28

RS = √28                  28 is slightly > 25   and since  √25 =5

RS = 5.3                    actually 5.2915  to a few more significant digits

pls mark brainliest

I can't see pictures, but to graph y=2x, you have to make 2x into slope form.

Just write 2 as a fraction, or 2/1. 2 is the rise, and 1 is the run. So start at the origin, or (0,0), and go up 2 units, then 1 unit right. So you start at (0,0), then now you should be at (1,2). Repeat the process to make a straight line.

Answer:

HCF = 14

LCM = 1680

Step-by-step explanation:

Factorizing the given values

210 = 2 * 3 * 5 * 7

112 = 2 * 2 * 2 * 2 * 7

Since 2 * 7 is common to both factors

Hence the HCF = 2 * 7 = 14

For LCM, we we will multiply all the prime factors that are in both

LCM = 2* 2 * 2 * 2 * 3 * 5 * 7

LCM = 112 * 15

LCM = 1680

Hence the LCM is 1680

Answer:

The answer is A

Step-by-step explanation:

7 + -8 = -1

-6 + -7 = -13

2 + 5 = 7

6 + -1 = 5

-5 + -9 = -14

-7 + 7 + 0

you can then eliminate B.

Answer:

a baby weight more because the baby will grow and will weight more then a puppy

Step-by-step explanation:

Answer:

A puppy that weights 8.5 kilograms weighs more.

Step-by-step explanation:

A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.

Puppy's Weight Kilograms: 8.5

Puppy's Weight Pounds 18.7

Baby's Weight Kilograms: 5

Baby's Weight Pounds: 11

Weight in Kilograms: Puppy: 8.5 > Baby: 5

Weight in Pounds: Puppy: 18.7 > Baby: 11

Therefore, the puppy is heavier.

Answer:

the mean is 3.95

median is 2.75

Step-by-step explanation:

I'd say that the mean is the better center, because you need to even it all out. you have one big number compared the rest.

The median is a better center for this data since since that number is the common size of acres not the highest or lowest acre per 1000 residents
