Answer:

74cm

Step-by-step explanation:

If 24cm and 70cm are given sides of a right triangle, we can use the pythagorean theorem to find out the hypotenuse.

$a^{2} +b^{2} =c^{2}$ where a and b are sides of the right triangle and c is the longest side, or hypotenuse, of the right triangle.

Let's plug both 24 and 70 into the equation.

$24^2+70^2=c^2$

5476= $c^2$

To get c alone by itself, we have to square root both sides.

$\sqrt{5476}=\sqrt{c^2 }$

74=c

The longest side, or the hypotenuse, length, is 74cm.

3. A research study asked children which of four different emotions they associated with the color red. The response and gender

user100 [1]

Answer:

This is required solution

Step-by-step explanation:

Given that:

for male

joy = 28

happiness = 20

love = 40

anger = 18

a] we need to calculate the percentage of emotions for the male

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{28}{106}\times100$

percentage of joy = 26.41

percentage of happiness = $\dfrac{20}{106}\times100$

percentage of happiness = 18.86

percentage of love = $\dfrac{40}{106}\times100$

percentage of love = 37.73

percentage of anger = $\dfrac{18}{106}\times100$

percentage of anger = 16.98

for female

joy = 61

happiness = 25

love = 80

anger = 60

we need to calculate the percentage of emotions for the female

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{61}{226}\times100$

percentage of joy = 26.99

percentage of happiness = $\dfrac{25}{226}\times100$

percentage of happiness = 11.06

percentage of love = $\dfrac{80}{226}\times100$

percentage of love = 35.39

percentage of anger = $\dfrac{60}{226}\times100$

percentage of anger = 26.54

B] We need to draw a bar graph for male and female

using percentage of emotion of male and female

according to using percentage we draw a bar graph using data of part A.

Hence, this is required solution

Answer:

Step-by-step explanation:

Summation means that you are adding together all the numbers that result from putting in the numbers 5-11 for i:

(-7 - 6(5)) + (-7 - 6(6)) + (-7 - 6(7)) + ( -7 - 6(8)) + ( -7 - 6(9)) + ( -7 - 6(10)) + ( -7 - 6(11)) which gives you the numbers:

-37 + -43 + -49 + -55 + -61 + -67 + -73 = -385

Write a function in terms of t that represents the situation.

AURORKA [14]

The exponential function is given by $y = 210000(1.125)^t \\$

<h3>exponential function</h3>

An exponential function is in the form:

$y=ab^x$

Where a is the initial value of y and b is the multiplier factor

Let y represent the population after t years.

Given an initial population of 210000, hence:

a = 210000

The population increases by 12.5% each year, hence:

b = 100% + 12.5% = 112.5% = 1.125

The exponential function is given by $y = 210000(1.125)^t \\$
