Describe how to estimate a non-perfect square root to the hundredths place without using a calculator.

1) find the perfect square closest to the number
2) take that square root, and then divide your number by that number
3) take the average of the perfect square root (the whole number) and the result of dividing your original number by that root. 

Example: Approximate square root of 27
Closest perfect square: 25
Square root: 5
27 ÷ 5 = 5.4
Average between 5 and 5.4 = 5.20
5.2² = 27.04. Fast and not a bad approximation!

<u>Sample Response:</u> Approximate between two whole numbers by finding the perfect squares nearest to the target number. Identify which value the non-perfect square root is closest to, then use the iterative process to approximate further to the tenths place, and then further to the hundredths place.

Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
vagabundo [1.1K]

Answer:

x = 19

<B = 125°

Step-by-step explanation:

The sum f angle <D and angle <A is equal to 180° because these angles are supplementary

75° + 5x + 10 = 180° add like terms

85 + 5x = 180 subtract 85 from both sides

5x = 95 divide both sides by 5

x = 19

Same rule goes for angle <C and angle <B

<B + 55° = 180 subtract 55 from both sides

<B = 125°

Define a function. Describe what the vertical line test is used for. Describe a real life situation that can be represented by a
Marrrta [24]
A function is a relationship with a quantity (number). For example, if you made a table, and had one side be 1 2 3 4 5 (X axis) and then the y axis (other side) be 5, 10, 15, 20, 25, the function (rule) would be y= x5. The vertical line test is used to see if a graph has a function or not, so if it creates a vertical line on a graph, it has a function.
A real life situation would be miles per hour, so, for the x axis (hours) it said 1, and for the y axis (miles) it would be 60, this means in a duration of 1 hour you went 60 miles. Well, lets say you went 2 hours driving, the miles would be 120. 
For 3 hours, it would be 180. The function here is y= x60!

The water level varies from 12 inches at low tide to 52 inches at high tide. Low tide occurs at 9:15 a.m. and high tide occurs a
balandron [24]
52 inches - 12 inches = 40 inches
amplitude:  a = 40 inches / 2 = 20 

<span>f(x)=20cos(bx)+c</span>
the value of c is 32... since the centre of the has been moved up 32 units

the minimum amplitude =  32 - 20 = 12
the maximum amplitude = 32 + 20 = 52

<span>f(x)=20cos(bx)+32</span><span>
if the curve takes 6 1/4 hours from low to high tides (9:15 am to 3:30 pm)  then it will take 12 1/2 hours to complete a full cycle.

adjust the period by converting 12 1/2 hours to an angle measure.

360</span>°/12 = 30° 
30° / 12 = 15°

12 1/2 = 360° + 15° = 375°

f(x) = 20 cos(375°) + 32
f(x) = 20 * 0.97 + 32
f(x) = 19.4 + 32
f(x) = 51.4
