hi cn i pleas have help on this question

Answer:

option a

1/3=x/42

..........

If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:

f'(x) = 4x ³ - 4x

f''(x) = 12x ² - 4

Solve f'(x) = 0 to get the critical points of f(x) :

4x ³ - 4x = 4x (x ² - 1) = 0

→   x = -1, x = 0, x = 1

Check the sign of the second derivative at each of these points:

f'' (-1) = 8 > 0

f'' (0) = -4 < 0

f'' (1) = 8 > 0

These indicate the presence of

• two minima of f (-1) = 2 and f (1) = 2

• one maximum of f (0) = 3

which makes C the correct answer.

Answer: 35≤ x ≤95  

x ≤ 2y

y≤125

Step-by-step explanation:

In an optimization problem, a constraint is a condition with variables that the solution must meet.

Let x = Number of cinnamon strawberry raisin buns.

y =  Number of cinnamon chocolate mango buns baked.

"at least 35 and not more than 95 cinnamon  strawberry raisin buns per day."

⇒ 35≤ x ≤95  

"cinnamon strawberry raisin buns cannot exceed twice the number of cinnamon chocolate mango buns baked."

⇒ x ≤ 2y

" cinnamon strawberry raisin buns cannot exceed 125 per day"

⇒ y≤125

Hence, the constraints are:

35≤ x ≤95  

x ≤ 2y

y≤125

Answer:

<3, 7> and [3 7], b and c

Step-by-step explanation:

multiply the vector by the matrix {1 0} (top row) {0 -1} bottom row. So you flip the sign of the -7 and this gives us +7.

Answer:

the number of students enrolled this year is 21,600 students

Step-by-step explanation:

The computation of the number of students enrolled this year is as follows:

= Number of students enrolled last year × increased percentage

= 20,000 students × 108%

= 21,600 students

hence, the number of students enrolled this year is 21,600 students

Answer: 70%

Step-by-step explanation:

Total number of jersey = 50.

Total number of medium sized jersey = 35

The percent of the jerseys that are medium sized jerseys will be:

= Number of medium sized / Total number of jersey × 100

= 35 / 50 × 100

= 70%

Answer:

m<5 = m<7 = 127

Step-by-step explanation:

m<2 = m< 8 because they are alternate interior angles.

So angle 8 is 53 degrees.

m<8 + m<7 = 180 because they form a straight angle.

Since angle 8 is 53 degrees as previously established, angle 7 has to be 127 degrees.

And since angles 7 and 5 are opposite angles, they have the same value, so both angles are 127 degrees.

Given:

The coordinates of point A are (7,4).

It is dilated from the origin by a scale factor r = 3.

To find:

The coordinates of A'.

Solution:

If a figure is dilated from the origin by a scale factor k, then

[tex](x,y)\to (kx,ky)[/tex]

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

[tex](x,y)\to (3x,3y)[/tex]

Using this rule, we get

[tex]A(7,4)\to A'(3(7),3(4))[/tex]

[tex]A(7,4)\to A'(21,12)[/tex]

Therefore, the coordinates of point A' are (21,12).

Answer: A, (6, -9)

Step-by-step explanation:

Answer:

Katrina would need to buy 20 sweatshirts.

Step-by-step explanation:

The number of sweatshirts Katrina would need to order from  each company can be determined by forming the linear equation in two variables.

Given :

Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.

So, the cost for ordering the sweatshirt from the company MH Design is:

[tex]21.50x = c[/tex]

Now, the cost for ordering the sweatshirt from the company Print Rich is:

18y + 70 = c'

Given that the number of sweatshirts Katrina would need to order from  each company for the costs to be the same. So :

21.5x = 18y + 70

Now, put the value of x and y so, that in the above equation, both sides become equal.

Answer:

f(g(t)) = 2t² + 1

Step-by-step explanation:

You can solve this simply by substituting g(t) into f(t), and solving for f(g(t)):

[tex]f(t) = 2t + 5\\\\g(t) = t^2 - 2\\\\f(g(t)) = 2(g(t)) + 5\\\\f(g(t)) = 2(t^2 - 2) + 5\\\\f(g(t)) = 2t^2 - 4 + 5\\\\f(g(t)) = 2t^2 + 1[/tex]

Step-by-step explanation:

Answer: 220%

Step-by-step explanation:

165 of 75 can be written as:

165 /75

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

165 /75  ×  100 /100  = ( 165 × 100 /75 ) ×  1 /100  =  220 /100

Therefore, the answer is 220%
