Mathematics
1 answer:
Genrish500 [490]3 years ago
6 0

Answer:

6

Step-by-step explanation:

since it's a right triangle you can use the Pythagorean Theorem

2.7² + b² = 6.5²

7.29 + b² = 42.25

b² = 34.96

b = \sqrt{34.96} which equals 6 when rounded to the nearest tenth

Answe 25 and 26 easy
Zina [86]

Answer:

25. rational

26. irrational

Step-by-step explanation:

A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.

An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.

25.

When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.

26.

The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.

Write the expression in standard form. 1/4 (4x+8)
slavikrds [6]
Here, 1/4 (4x + 8)

Apply the distributive property which tells: a(b + c) = ab + ac

= 4x/4 + 8/4

= x + 2   [ Final Answer ]

What are the transformations? f left parenthesis x right parenthesis space equals negative 3 left parenthesis x minus 4 right pa
Phoenix [80]

Answer:

The graph of the functions moves 4 units right, 3 units up stretches vertically by a factor of 3 and reflects horizontally.

Step-by-step explanation:

In order to find the function transformations, we must first determine what the base function is:

f(x)=x^{2}

Next, we need to determine how the function is being affected by the transformations.

When the graph of the function moves 4 units right, we mus subtract 4 units from x, so the function looks like this then:

f(x)=(x-4)^{2}

If we need to stretch it vertically by a factor of 3, we need to multiply the function by 3:

f(x)=3(x-4)^{2}

If we need to reflect it horizontally, then we turn the 3 into a negative so we get:

f(x)=-3(x-4)^{2}

And finally, if we wanted to move the graph up by 3 units, then we need to add 3 units to the whole graph, so we get:

f(x)=-3(x-4)^{2}+3

in the attached picture you will be able to see the graph of the base function with all the transformations.

9 + n/2 &gt; 16<br>show work please
iVinArrow [24]

1. write the division as a fraction
9+n/2>16 → 9+1/2n>16
2. multiply both sides of the inequality by 2
2x9+2x1/2n>2x16
3. multiply the numbers and reduce the numbers with greatest common divisor 2 (remove number 2, the common factor from equation)
18+n>32
4. move constant to the right by adding its opposite to both sides
18+n-18>32-18
5. eliminate the opposites
n>32-18
6. subtract the numbers
n>14
hope this helped!
