Answer:
It cooled 58.4 degrees
Step-by-step explanation:
T(t) = 68 + 144e ^(-.052t)
We want to find the value when t= 10
T(10) = 68 + 144e ^(-.052*10)
= 68 +85.611
T(10) =153.611
We also need to know
T(0)= 68 + 144e ^(-.052*0)
=68+144
=212
We want to know how much it cools
That would be the temperature at time 0 minus the temperature at time 10
T(0) - T (10)
212-153.611
58.389
To the nearest tenth
58.4 degrees
The most specific name is trapezoid
Answer:
Option C. −4≤t≤−3
Step-by-step explanation:
we have

This is the equation of a vertical parabola written in vertex form
The parabola open upward (the leading coefficient is positive)
The vertex is a minimum
The vertex is the point (-3,5)
The function is increasing in the interval [-3,∞)
The function is decreasing in the interval (-∞,-3]
The function will have a negative average rate when the function will be decreasing
therefore
the answer is option C
The Type B trees produces 120 pears.
<h3>What is meant by percentage?</h3>
A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.
<h3>
How many pears did the Type B trees produce?</h3>
- Type A trees produced 20 percent more pears than Type B trees did
- Type A trees produced 144 pears.
Let us consider, Type B produced 100% pears.
So, Type A will produce 120%of B, that is 144
144 = 120/100
B
simplifying the above equation, we get
144
100 = 120B
B = 14400/120
B = 120
The value of B = 120.
Hence, the Type B trees produces 120 pears
Therefore, the correct answer is option B) 120.

Answer:
I think the answer is b^2=8^2-4^2
Step-by-step explanation:
The equation is A^2+B^2=C^2
C^2-A^2=B^2
C^2-B^2=A^2
C is the hypotenuse. You know what a is and all you have to do is show the equation
