Step-by-step explanation:

The link provided will take you to a differently worded explanation from another user.

You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:

c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.

Step-by-step explanation:

Answer:

steps below

Step-by-step explanation:

Step 1: Cot A / (1+cot A) * Cot B / (1+cot B )

= (Cot A  * Cot B) / ((1+cot A) *(1+cot B ))

= (Cot A  * Cot B) / (1+cot A+cot B+cot A cot B)

= (Cot A  * Cot B) / ((1+cot A+cot B)+ (cot A cot B))     : a

Step 2: (cot A * cot B -1) / (cot A + cot B) = cot (A+B) = cot 225° = 1  (formula)

            cot A * cot B -1 = cot A + cot B

            cot A * cot B  = 1 + cot A + cot B       (substitute a)

Step 3:

Cot A / (1+cot A) * Cot B / (1+cot B )

= (Cot A  * Cot B) / ((cot A * cot B)+ (cot A * cot B))

= (Cot A  * Cot B) / (2 * (cot A * cot B))

= 1 / 2

= 0.5

Answer: Option D is correct.

Step-by-step explanation: An exponential function is in the form of  where a is the initial value and b≠ 0 , b >1 .

Given: The function f(x) = y =            ......[1]

The domain is all real numbers and the range is y > 0.

y-intercept defined as the graph crosses the y-axis.

Substitute the value of x= 0 in [1] to solve for y;

y =   = 4

y-intercept = (0, 4)

End behavior:

when b =3 >1

then;

as  ,  

as   ,  

therefore, the only graph which represents the function y =    is Option D

Answer:

a) The probability that Tommy takes a yellow counter is 0.20.

b) The probability that Tommy takes a blue counter is 0.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

There are 5 red counters, 2 yellow counters and 3 green counters in a jar. Tommy takes a counter at random from the jar.

a) What is the probability that he takes a yellow counter?

b) What is the probability that he takes a blue counter?

The explanation of the answers are now given as follows:

a) What is the probability that he takes a yellow counter?

This can be calculated as follows:

Total number of counters in the jar = Number of red counter in the jar + Number of yellow counter in the jar + Number of green counter in the jar = 5 + 2 + 3 = 10

Probability of taking a yellow counter = Number of yellow counter in the jar / Total number of counters in the jar = 2 / 10 = 0.20

Therefore, the probability that Tommy takes a yellow counter is 0.20.

b) What is the probability that he takes a blue counter?

This can be calculated as follows:

Number of blue counter in the jar = 0

Probability of taking a blue counter = Number of blue counter in the jar / Total number of counters in the jar = 0 / 10 = 0

Since there no blue counter in the jar, the probability that Tommy takes a blue counter is therefore 0.

Answer:

temp after 7 minutes is 135°

temp after 't' minutes:  y = 65 + 10t

Step-by-step explanation:

Answer:

1) 135°

2) 65° + 10t°

Step-by-step explanation:

What is the temperature of the oven 7 minutes after being turned on?

65° (initial temperature) + 10° (temperature increase per minute) × 7 (amount of minutes)

10 × 7 = 70

65° + 70° = 135°

What is the temperature of the oven t minutes after being turned on?

65° (initial temperature) + 10° (temperature increase per minute) × t (amount of minutes)

10 × t = 10t

65° + 10t°

Answer:

[tex]\boxed {\boxed {\sf (5g^2+2)(2g-5)}}[/tex]

Step-by-step explanation:

We are given the expression:

[tex]10g^3-25g^2+4g-10[/tex]

There are no common factors between the four numbers, however the first two have a common factor and the last two do too. Therefore, we can factor by grouping.

Group the first two terms and the last two.

[tex](10g^3-25g^2)+(4g-10)[/tex]

Find the greatest common factor (GCF) of the first group. It is 5g². Factor it out of the first group. You can do this by dividing both terms by the GCF.

[tex]5g^2 (2g-5) + (4g-10)[/tex]

Repeat with the second group. The GCF is 2.

[tex]5g^2 (2g-5) + 2(2g-5)[/tex]

There is another GCF: 2g-5. We can factor this out of both terms.

[tex](5g^2+2)(2g-5)[/tex]

This cannot be factored further, so it is the answer.

Answer:

6 ways

Step-by-step explanation:

The number of ways he can display the stamps as follows:

Here we find the factors of 32

i.e.

= 1 × 32 represent 1 row, 32 stamps each

= 2 × 16 represent 2 rows, 16 stamps each.

= 4 × 8 represent 4 rows, 8 stamps each.

= 8 × 4 represent 8 rows with 4 stamps each

= 16 × 2 represent 16 rows with 2 stamps each

= 32 × 1 represent 32 rows with 1 stamp each

So in 6 ways he can displayed
