Answer:
-2 degrees per hour
Step-by-step explanation:
Rate of change = -3 1/2 / 1 3/4
= -7/2 / 7/4
= -7/2 * 4/7
= -28/14
= - 2
Answer:
16/19
Step-by-step explanation:
x = 1 / -38 × -32
x = 16 / 19 or 0.8421052632

Using the given digits only once , the four 2 digit prime numbers are 23 , 41 , 59 , 67 and the the sum of the 4 prime numbers is 190 .
Prime Numbers can be defined as numbers that is greater than 1 and whose only factors are 1 and itself .
For Example : 2 is prime number , 11 is a prime number .
In the question ,
9 digits are given as 1, 2, 3, 4, 5, 6, 7, and 9
we have to form 4 two - digit prime numbers , using each digit only once ,
So , the prime numbers using the given digits using the digits only once is
(i) 23
(ii) 41
(iii) 59
(iv) 67
and the sum of the 4 prime numbers is = 23 + 41 + 59 + 67
= 190
Therefore , the 4 prime numbers are 23 , 41 , 59 , 67 and their sum is 190 .

Answer:
See the explanation.
Step-by-step explanation:
We are given the function f(x) = x² + 2x - 5
Zeros :
If f(x) = 0 i.e. x² + 2x - 5 = 0
The left hand side can not be factorized. Hence, use Sridhar Acharya formula and
and
⇒ x = -3.45 and 1.45
Y- intercept :
Putting x = 0, we get, f(x) = - 5, Hence, y-intercept is -5.
Maximum point :
Not defined
Minimum point:
The equation can be expressed as (x + 1)² = (y + 5)
This is an equation of parabola having the vertex at (-1,-5) and axis parallel to + y-axis
Therefore, the minimum point is (-1,-5)
Domain :
x can be any real number
Range:
f(x) ≥ - 6
Interval of increase:
Since this is a parabola having the vertex at (-1,-5) and axis parallel to + y-axis.
Therefore, interval of increase is +∞ > x > -1
Interval of decrease:
-∞ < x < -1
End behavior :
So, as x tends to +∞ , then f(x) tends to +∞
And as x tends to -∞, then f(x) tends to +∞. (Answer)
