The equation ​ yˆ=−0.37x2+6.15x+52.3 ​ approximates the average temperature in October in degrees Fahrenheit at an agricultural
sweet-ann [11.9K]

Answer:

The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

Solution:

Number of hours after 5 a.m.: x

At 10 a.m.→x=10-5→x=5

​ yˆ=−0.37(5)^2+6.15(5)+52.3

yˆ=−0.37(25)+30.75+52.3

yˆ=−9.25+30.75+52.3

yˆ=73.8

Answer: The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

Which is the best approximation for the measure of angle ABC?
ankoles [38]
We can find the approximate measurement of angle ABC  and it is equal to 180°. The summation of all angles in a triangle is 180°.
Solving for x or angle B, we need to used Pythagorean theorem and SOH CAH TOA.
Solving for angle A:
sinA = 10.5/20
A = 31.67°

Solving for angle B:
180° = ∠C + ∠B + ∠A
180° = 90° + ∠B + 31.67
∠B = 58.33°

The x value is 58.33°.

Can you use the values in Pascal’s triangle to find the powers of 11? Explain.
VladimirAG [237]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Yes!

Ultimately (it states) all numbers in existence can be extracted from Pascal's Triangle.  Using his binomial formation of: <em>(a + b)^0 = 1</em> , where y is the number you are using.  and <em>(a + b)^x </em>is the equation you use to find the answer of that row...  the usage of that row, and the formation of its components is how you find the powers of numbers in a given row...

You would be able to find each row of the Triangle, and by using the association of Multiplication, addition, distribution, and

If you look at the images below you will notice that to find a power of 11 at it's 6th power, you look at the 6th row of Pascal's Triangle... Although not completely relevant, I also added an image of using his Triangle to find the Powers of 2...

<em>Remember, The images below are of only smaller versions of Pascal's Triangle, as his Triangle is of infinite size...</em>
