The solution of the inequality is 1<x<2.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations.

According to the given statement;

2 < 3x - 1 < 5

or, 2 + 1 < 3x - 1 + 1 < 5 + 1

or, 3 < 3x < 6

Divide the whole by 3, we get

or, 3/3 < (3/3)x < 6/3

or, 1 < x < 2

hence, the solution of the inequality is 1<x<2.

Answer:

We get that the value of (f + g​)(x​) is 11 x - 1.

Function: a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

We are given the two functions:

f(x) = 4 x + 3

g(x) = 7 x - 4

We need to find:

(f + g​)(x​)

We know that this is equal to

= f(x) +g(x)

Substituting the values, we get that:

= 4 x + 3 + 7x - 4

Combining the like terms, we get that:

= 11 x - 1

Therefore, we get that the value of  (f + g​)(x​) is 11 x - 1.

Answer:

sin 11pi/3 = - root3/2

cos 11pi/3 = 1/2

tan 11pi/3 = - root3

csc11pi/3 =-2root3/3

sec11pi/3= 2

cot11pi/3 = -root3/3

see image

Step-by-step explanation:

This is a question that you should use the Unit Circle to find the answers. Unit Circle looks like a horrible math nightmare pizza, but it is really a great big giant Answer Key. It has all the trig answers on it.

First, change 11pi/3 to an angle that IS on the Unit Circle. See image for three ways to change 11pi/3 to an equivalent (on the UnitCircle) angle 5pi/3.

Then, since the Unit circle is the Answer Key. Use the x and y given, in the form (x, y) to find all 6 trig values.

Memorize for this type of question:

sin = y (they both have that long i sound)

cos = x

tan = y/x

csc (flip over sin) = 1/y

sec = 1/x (flip cos)

cot = x/y (flip tan)

Also, to make things hairier, you have to know how to rationalize the denominator. This just means you canNOT leave a sqrt symbol on the bottom of a fraction.

And unfortunately, if you never learned how to manipulate a fraction over a fraction, you will have to do that too. Use Keep-Change-Flip. That makes it super do-able. See image.

The solution for the equation 7x-4 = -18 is x = -2

The equation given is, 7x - 4 = -18.

We will try to solve this equation using elimination method in the following steps.

7x-4= -18

⇒ 7x-4+4 = -18+4

⇒7x = -14

⇒7x/7 = -14/7

⇒x = -2 is the solution for the given equation.

In the first step, we added 4 on both sides to eliminate -4 on the left side.

In the next step, we divided the both sides by 7 to eliminate the 7 on the left side. Finally, we got the solution as x = -2.

Using proportions, it is found that:

a) You need 15 tablespoons of brown sugar.

b) You need 8 tablespoons of baking soda.

c) You need 10 cups of brown sugar.

d) You need 24 cups of baking soda.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for ratio problems.

For this problem, the recipe uses a 2:5 ratio of baking soda to brown sugar, hence:

Hence, for item a, the amount is:

5/2 x 6 = 30/2 = 15.

You need 15 tablespoons of brown sugar.

For item b, the amount is:

2/5 x 20 = 40/5 = 8.

You need 8 tablespoons of baking soda.

For item c, the amount is:

5/2 x 4 = 20/2 = 10.

You need 10 cups of brown sugar.

For item d, the amount is:

The average rate of change of the given function f over the intervals-

f(x) = x²/8 ; x=a=1

the average rate of change of f(x) over the time interval [a, a + h] is

rc= [f(a +h) - f(a) ] / [(a +h)-a] = [(a +h)²/8 - a²/8] /h = 1/h [ (a²/8 +a*h/4+ h²/8) - a²/8]

= a /4+ h/8

then

rc= a/4+ h/8

for x=a=1 and h=1

rc= 1/4 + 1/8 = 0.375

for a=1 and h=0.1

rc= 1/4 + 0.1/8 = 0.2625

for a=1 and h=0.01

rc= 1 /4+ 0.01/8 = 0.25125

for a=1 and h=0.001

rc= 1/4 + 0.001/8 = 0.250125

for a=1 and h=0.0001

rc= 1 /4+ 0.0001/8 = 0.2500125

when h goes smaller , the average rate of change gets closer to the instantaneous rate of change of f(x) in x=a=1 (the derivative of f in a=1) , that is

f'(x) = x

Answer:

  (x, y, z) = (-62, 50, -9)

Step-by-step explanation:

You want the solution to this system of equations using the inverse of the coefficient matrix.

  x+2y+3z = 11

  2x+3y+4z = -10

  −x−4y−8z = −66

The inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. There are some shortcuts that can be used to make the computation easier. Easiest is letting a calculator find the matrix inverse. (See the first attachment.)

The solution to the set of equations is the product of the inverse matrix and the constant vector on the right of the equal signs. That, too, can be found using a calculator. (See the second attachment.)

The solution is (x, y, z) = (-62, 50, -9).

Using the Pythagorean Theorem, the distance between Pole X and Pole Z is of 15.3 m.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

The first part of the distance is the hypotenuse of a right triangle of sides 0.5 and 2.5, tracing a right triangle at the top of pole X and tracing it to segment Y, hence:

df² = 0.5² + 2.5²

df = sqrt(0.5² + 2.5²)

df = 2.55m.

For the second part, we apply equivalent triangles, as we can also trace a right triangle at the top of segment Y to segment Z, hence:

0.5/2.5 = df/ds

1/5 = 2.55/ds

ds = 2.55 x 5 = 12.75m

Then the total distance is:

2.55 + 12.75 = 15.3 m.
