Answer:
x=24
Step-by-step explanation:
We can use the Pythagorean theorem to find x
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
7^2 + x^2 = (x+1)^2
FOIL the right side (x+1) * (x+1) = x^2 +1x +1x+1 = x^2+2x+1
49+x^2 = (x^2 +2x+1)
Subtract x^2 from both sides
49+x^2-x^2 = (x^2 +2x+1) -x^2
49 = 2x +1
Subtract 1 from each side
49-1 = 2x+1-1
48 =2x
Divide by 2
48/2 = 2x/2
24 =x
Answer:
The rate at which the temperature is changing at 4 p.m. is
Step-by-step explanation:
The derivative, is the instantaneous rate of change of with respect to when .
We know that the daily temperature in degrees Fahrenheit of Phoenix in the summer can be modeled by the function
,
where is hours after midnight.
To find the rate at which the temperature is changing at 4 p.m. First, we must find the derivative of this function.
So,
Then, at 4 p.m means because is hours after midnight.
Thus,
The rate at which the temperature is changing at 4 p.m. is
By critically observing the two triangles, we can deduce that they: B. might not be congruent.
<h3>The properties of similar triangles.</h3>
In Geometry, two triangles are said to be similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.
By critically observing the two triangles, we can logically deduce that the three angles of both triangles are congruent in accordance with AAA similarity postulate:
However, AAA isn't a congruence postulate and as such all similar triangles might not be congruent.
