Given: 3x < -6. Choose the solution set.

{x | x < -2}
{x | x > -2}
{x | x < 2}
{x | x > 2}

Answers

$3x\ \textless \ -6 :$

Divide both sides by 3 :

$(3x)/(3) = (-6)/(3)$

$x\ \textless \ -2$

Answer A

{x | x < -2}

Use integration by parts to integrate sin2x between pi and 0

Answers

Answer:

$\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = 0$

General Formulas and Concepts:

Calculus

Integration

Integrals

Integration Rule [Fundamental Theorem of Calculus 1]: $\displaystyle \int\limits^b_a {f(x)} \, dx = F(b) - F(a)$

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

U-Substitution

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx$

Step 2: Integrate Pt. 1

Identify variables for u-substitution.

Set u: $\displaystyle u = 2x$
[u] Differentiate: $\displaystyle du = 2 \ dx$
[Bounds] Switch: $\displaystyle \left \{ {{x = 0 ,\ u = 2(0) = 0} \atop {x = \pi ,\ u = 2 \pi}} \right.$

Step 3: Integrate Pt. 2

[Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = (1)/(2) \int\limits^0_(\pi) {2 \sin (2x)} \, dx$
[Integral] U-Substitution: $\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = (1)/(2) \int\limits^0_(2 \pi) {\sin u} \, du$
Trigonometric Integration: $\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = (1)/(2)(-\cos u) \bigg| \limits^0_(2 \pi)$
Evaluate [Integration Rule - Fundamental Theorem of Calculus 1]: $\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = (1)/(2)(0)$
Simplify: $\displaystyle \int\limits^0_(\pi) {\sin (2x)} \, dx = 0$

Determine the intercepts of the line.
y= 10x - 32
y-intercept:
x-intercept:

Answers

Answer:

see below

Step-by-step explanation:

To find the x intercept set y =0 and solve for x

0= 10x - 32

32 = 10x

Divide by 10

3.2 = x

The x intercept

( 3.2,0)

To find the y intercept set x =0 and solve for y

y= 0 - 32

y = -32

( 0, -32)

Answer:

(0, -32)

(3.2, 0)

Step-by-step explanation:

The line is in slope intercept form. It is easy to identify the y-intercept.

$y=mx+b$

The y-intercept is (0,-32). '-32' replaces the 'b' in the equation.

To find the x-intercept, set the value of 'y' to zero and solve for 'x'.

$0=10x-32\n\n0 + 32 = 10x-32+32\n\n32=10x\n\n(32)/(10)=(10x)/(10)\n\n(32)/(10)=x\n\n\rightarrow (32/2)/(10/2)=(16)/(5)\n\n \boxed{x=(16)/(5)}$

The x intercept is (16/5, 0).

This can also be expressed as (3.2, 0).

Hope this helps.

Max scored 9 runs on Monday and 11 runs on Tuesday. How many runs did he score in all?

Answers

The totalrun he scored in all would be 20.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that max scored 9 runs on Monday and 11 runs on Tuesday.

We need to find the total number of scores he runs in all.

The run scored on Monday = 9

The run scored on Tuesday= 11

The total = run scored on Monday + run scored on Tuesday

The total = 9 + 11 = 20

The totalscore he runs in all would be 20.
