Which of these is a tangent line to y= -x^2 at x=4
Answers
Answer:
Step-by-step explanation:
an equation of this tangent is : y = f'(4)(x-a)+f(4)
a = f'(4)
f(x) = - x²
a=4
f'(x) = -2x
f'(4) = -2(4) = -8
f(4) = -(4)² = -16
so : y = - 8 (x-4)-16
y = - 8x +16

The number of chips of different colors in Vicky's bag is shown below: 5 blue chips 11 pink chips 9 white chips. Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? 5 over 25 multiplied by 5 over 25 equals 25 over 625, 5 over 25 plus 5 over 25 equals 10 over 25, 5 over 25 multiplied by 4 over 24 equals 20 over 600, 5 over 25 plus 4 over 24 equals 220 over 600.

The total yards of tubing the plumber will use is given by A = 8 yards
What is unit conversion?
In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the total yards of tubing the plumber will use be A
Now , the equation is
Let the total inches of tubing used for each washing machine = 16 inches
And , from the unit conversion ,
16 inches = ( 16/36 ) yards
So , the number of washing machines = 18 machines
Now , the total yards of tubing the plumber will use A = number of washing machines x 0.444
On simplifying , we get
The total yards of tubing the plumber will use A = ( 16 / 36 ) x 18
The total yards of tubing the plumber will use A = 8 yards
Hence , the total yards is A = 8 yards

Some of the fractions that are equivalent to 4/7 are 8/14, 12/21, 16/28, 20/35 e.t.c
What is equivalent expression?
Equivalentexpressions are expressions that work the same even though they look different.
If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
For example , 5 × 4 = 20 and 2 × 10 = 20 , so the two expressions are equivalent and they have thesame value
To find the equivalent of 4/7, we can multiply through by a factor of 2, 3 , 4 ,5 e.t.c
Therefore 4/7 = 8/14 = 12/21 = 16/28 = 20/35
