85 is the answer. 2+ 78 = 80 + 5 += 85.

Well 2+5=7 and when you add 7 to 78 you get 85. Hope that helped :)

PLEASE ANSWER RIGHT AEAY
madam [21]

Answer:

y=Sin(x-\frac{\pi}{4})

Step-by-step explanation:

The basic graph of y = Sin(x), starts at x = 0.

Looking at the graph, the basic sin curve starts at x = π/4

So this function is the parent sin function shifted π/4 units to the right.

<u>Note:</u>

y = Sin(x-a)  is the parent function ( y= Sinx) shifted a units right

y = Sin(x+a)  is the parent function shifted a units left

<em>Since this function is shifted </em>π/4 units right, the equation would be:

y = Sin (x-π/4)

The third answer choice is right.

(x−7)2−25=0<br><br> smaller x =<br> larger x =
nexus9112 [7]

Remark

Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.

Solution

(x - 7)^2 - 25 = 0                 Add 25 to both sides

(x - 7)^2 - 25 + 25 = 25      Combine the left

(x - 7)^2 = 25                       Take the square root of both sides.

sqrt(x - 7)^2 = sqrt(25)

x - 7 = +/-   5                        Add 7 to both sides

x = 7 +/- 5

=========

x1 = 7 + 5

x1 = 12

x2 = 7 - 5

x2 = 2

Smallest x = 2

Largest x = 12

An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume)
timofeeve [1]

If the density of the man is 1.0321 grams per cubic cm. Then the body fat percentage will be 28.59%.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume) and apply a formula to convert it to a body fat percentage.

\rm BF = \left (\dfrac{4.57}{p} - 4.142 \right) \times 100

where BF = body fat and p = density in g/cm3 A man weighs 175 pounds.

A man weighs 175 pounds.

His total body volume is modeled by a cylinder with a height of 170 cm and a radius of 12 cm.

Then the density will be

\rm p = \dfrac{175 \times 453.592}{\pi \times 12^2 \times 170}\\\\p = \dfrac{79378.7}{76906.19}\\\\p= 1.0321 \ g/cm^3

Then the Body fat percentage will be

\rm BF = \left (\dfrac{4.57}{1.0321} - 4.142 \right) \times 100 \\\\\\BF = 0.2859 \times 100\\\\\\BF = 28.59\%
