Temka [501]3 years ago
4 0

Possible derivation:

d/da(4 - 8 a)

Differentiate the sum term by term and factor out constants:

= d/da(4) - 8 (d/da(a))

The derivative of 4 is zero:

= -8 (d/da(a)) + 0

Simplify the expression:

= -8 (d/da(a))

The derivative of a is 1:

= -8 1

Simplify the expression:

Answer: = -8

This graph shows the solution to which inequality?
sweet [91]

The graph shows the solution to inequality is; y > ¹/₃x - 2

<h3>How to interpret Inequality Graphs?</h3>

From the given graph, we see that the line joining the two dotted coordinates is a dashed line and as such the inequality will be less than or greater than.

Now, If a line passing through two points, then the equation of line is;

y - y1 = [(y2 - y1)/(x2 - x1)](x - x1)

Using the two given coordinates, we have;

y - (-3) = [(-1 - (-3))/(3 - (-3))](x - (-3))

y + 3 = (2/6)(x + 3)

y = ¹/₃x - 2

Since the related line is dashed and the shaded region is above the line, therefore the sign of inequality is >.

The graph shows the solution to inequality is;

y > ¹/₃x - 2

F(x)= -x2 + 1 for x =-3
dalvyx [7]

Answer:

f(-3) = -8

Step-by-step explanation:

It is given that f(x) = - x² + 1. Find the value of f(x) by substituting x = -3 into f(x)

f(x) = - x² + 1

f(-3) = -(-3)² + 1

= -9 + 1

= -8

bixtya [17]

Answer:

C

Step-by-step explanation:

1)Non- zeros (1,2,3,....) are always significant.

2)Captive zeros are significant too( zeros between non- zeros ).

3)Trailing zeros (zeros at the end) aren't significant always unless if there is a decimal point.

Such this question we have decimal point so we count them

Find each product by distributing.<br> (2a - 5)(a? – 2a + 1)
Westkost [7]

Answer:

A = 1 , 1 , \frac{5}{2}

Step-by-step explanation:

Given equation as

(2a -5) (a² -2a +1) = 0

Or, (2a - 5) (a - 1 )² = 0

Or, (2a - 5) (a - 1) (a - 1) = 0

So, value of a are :

2a - 5 =0,    a - 1 =0,    a- 1 = 0

i.e     a = \frac{5}{2}

and   a = 1 , 1
