as an equation

Answer:

go by basics u will get it easier

Step-by-step explanation:

assume X2 + e3x as some function t

now find derivative you get (1/t )dt/dx

now find dt /dx. simply derivative with respect to x

for second question use formula

dy/dx = - partial derivative of function with x / partial derivative of function with respect to y

Answer:

Maximum value equals 1/2

Minimum value equals -1/2

Step-by-step explanation:

The Sin Function when Graphed Shows a Range of [-1 , 1]

apply that on y=1/2 sin2x

y = 1/2 * 1 = 1

y = 1/2 * -1 = -1

so y = 1/2 , -1/2 .

dy/dx = 2 * 1/2 * cos2x

put dy/dx=0

cos2x=0

x= 45, x=135

Apply x values on y=1/2 sin2x

y = 1/2 , -1/2 .

Hope you understand it ^^.

Answer:

P =  24

After 24h will be 108p

Each c is 6m

12 laps

Step-by-step explanation:

36 - 33 = 3

33 - 30 = 3

30 - 27 = 3

27 - 3 = 24

12h = 36p

12h × 3 = 36h

So 36p need to × 3 too

36p × 3 108p

Because 3c to 5c, 18m to 30m need 12m. There was no 4c so the 12m need to  divide two. 12m ÷ 2 = 6m.

So each c is 6.

72 ÷ 6 = 12

The six is from the last question.

Answer:

D) [tex](x-4.5 )^{2} =16.25[/tex]

Step-by-step explanation:

Explanation

Given that the equation

   x² - 9 x +11 =7

 [tex]x^{2} -\frac{9}{2} (2x) +11=7[/tex]

[tex]x^{2} -\frac{9}{2} (2x) +(\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11=7[/tex]

By using (a-b)² = a²-2ab+b²

[tex](x-\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11=7[/tex]

[tex](x-\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11-7=0[/tex]

[tex](x-\frac{9}{2} )^{2} -(\frac{81}{4}) + 4=0[/tex]

[tex](x-\frac{9}{2} )^{2} +(\frac{-81+16}{4}) =0[/tex]

[tex](x-4.5 )^{2} -16.25 =0[/tex]

Final answer:-

[tex](x-4.5 )^{2} =16.25[/tex]

Answer is C) 3 And 4 only

Step-by-step explanation:

The system of inequalities that can be used to determine the amounts is given by:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

A system of inequalities works similarly to a system of equations, just the equality symbol is replaced by an inequality symbol(less, more, different,...).

In this problem, the variables are:

He bought glass vases that cost $22 each and ceramic vases that cost $14 each. The total cost of the vases came to more than $172, hence:

22x + 14y > 172.

Also, Ben bought no more than 10 vases in all, hence:

Answer:

f(3)=64

Step-by-step explanation:

f(3)=(1/8)(8 cubed)

f(3)= 8 to the negative one times 8 cubed

f(3)= 8 squared

f(3)=64

Answer:

f(3) = 64

Step-by-step explanation:

In this question, you would plug in "3" to "x" and solve.

Solve:

f(3) = (1/8)(8³)

f(3) = (1/8)(8·8·8)

f(3) = (1/8)(512)

f(3) = 512/8

Simplify.

f(3) = 64

Your final answer would be f(3) = 64

The cut is perpendicular to the base

Answer:18

Step-by-step explanation:

Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.

Taking a look at the examples again,

Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1

Sequence: 3, 8, 13, 18, … |Formula: b(n) = 5n - 2 | Recursive formula: b(n) = b(n-1) + 5, b(1) = 3

Answer:

Step-by-step explanation:

y = (1.066)x

The equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x

The sales tax is the amount charged on the price of goods and services.

Let x be the original cost for the meal

Let y be the cost after the sales

If the sales tax rate in Tyler's county is 6.6%, the tax charged is expressed as:

0.066 of theoriginal cost
0.066x

Cost after tax = original cost + tax
Cost after tax = x + 0.066x
y = 1.066x

Hence the equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x

Answer:

[tex]R_t=300\ \Omega[/tex]

Step-by-step explanation:

Given that,

R₁ = 100 ohms

R₂ = 200 ohms

We need to find the equivalent resistance of the circuit. So,

[tex]R_t=R_1+R_2\\\\R_t=100+200\\\\R_t=300\ \Omega[/tex]

So, the equivalent resistance is [tex]300\ \Omega[/tex].

Answer:

None, the sum of those angles does not equal 180 degrees

Answer:

The answer of this question is none. The sum of these three angles is 160°. So, none of the triangles can be constructed with angles measuring 60°, 60° and 40°

The sum of three angles is 160°
