Answer:

Step-by-step explanation:

Given the inequality −x − 10 > 14 + 2x

This are the steps to solve the expression for x;

−x − 10 > 14 + 2x

Step 1: Add to to both sides

−x − 10+10 > 14 + 2x+10

-x > 24+2x

subtract 2x from both sides

-x-2x >24+2x-2x

-3x>24

Divide both sides by 3;

-3x/-3 < 24/-3

x < -8 (Note the change in inequality sign. It was changed because we divided through with a negative value)

Answer:

3.Yes, because triangle ABC has a 90 degree angle.

4.No, because triangle XYZ doesn’t have a 90 degree angle.

The value of z-score such that 0.02 of the area lies to the right of z would be 2.06.

Given that,

0.02 of the area lies to the right of z.

Now, for the value of z such that 0.02 lies to the right of z, we can make use of the standard normal distribution table.

Since to determine the value of z such that 0.02 of the area lies to the right, we need to find the z-score associated with the cumulative probability of (1 - 0.02) = 0.98

Now for the value of 0.98 in the standard normal distribution table, we find that the corresponding z-score is 2.06.

Therefore, the value of z, rounded to two decimal places, is 2.06.

Answer:

The measure of angle B is 41.5°

The length of side a is 30.6 feet ⇒ to the nearest tenth

The length of side b is 32.9 feet ⇒ to the nearest tenth

Step-by-step explanation:

In the given Δ ABC

∵ m∠A = 38.1°

∵ m∠C = 100.4°

→ By using the fact above

∵ m∠A + m∠B + m∠C = 180°

∴ 38.1 + m∠B + 100.4 = 180

→ Add the like terms in the left side

∴ 138.5 + m∠B = 180

→ Subtract 138.5 from both sides

∴ m∠B = 41.5°

∴ The measure of angle B is 41.5°

∵ a is the opposite side of ∠A

∵ b is the opposite side of ∠B

∵ c is the opposite side of ∠C

→ By using the sine rule

∴ [tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]

∵ c = 48.4 ft, m∠A = 38.1°, m∠B = 41.5°, and m∠C = 100.4

→ Substitute them in the sine rule above

∴ [tex]\frac{a}{sin38.1}[/tex] = [tex]\frac{b}{sin41.5}[/tex] = [tex]\frac{48.4}{sin100.4}[/tex]

→ By using cross multiplication between the 1st and the 3rd fractions

∴ a × sin 100.4 = 48.8 × sin 38.1

→ Divide both sides by sin 100.4

∴ a = 30.61429861

∴ The length of side a is 30.6 feet ⇒ to the nearest tenth

→ By using cross multiplication between the 2nd and the 3rd fractions

∴ b × sin 100.4 = 48.8 × sin 41.5

→ Divide both sides by sin 100.4

∴ b = 32.87596206

∴ The length of side b is 32.9 feet ⇒ to the nearest tenth

Answer:

The 7th term of given sequence is: 448

Step-by-step explanation:

Given sequence is:

7,-14,28,-56​

Here

a1 = 7

a2 = -14

a3 = 28

First of all we have to find the common ratio. The common ration is the ratio between two consecutive terms of a geometric sequence and is same for all consecutive terms of a geometric sequence.

So,

[tex]r = \frac{a_2}{a_1} = \frac{-14}{7} = -2\\r = \frac{a_3}{a_2} = \frac{28}{-14} = -2\\[/tex]

The common ratio is -2.

The general formula for geometric sequence is given as:

[tex]a_n = a_1r^{(n-1)}[/tex]

Putting values

[tex]a_n = 7.(-2)^{n-1}[/tex]

For 7th term, putting n=7

[tex]a_7 = 7*(-2)^{7-1}\\= 7 * (-2)^6\\= 7 *64\\= 448[/tex]

Hence,

The 7th term of given sequence is: 448

Answer:

x = 6

Step-by-step explanation:

first find the angle

51 + 72 + x = 180

123 + x = 180

x = 180 - 123

x = 57

so the third angle is 57

now find the value of x in the given expression

8x + 9 = 57

8x = 57 - 9

8x = 48

x = 48/8

x = 6

now check whether the value of x is correct or not by evaluating the value of x in expression

8x + 9 = 57

8(6) + 9 = 57

48 + 9 = 57

57 = 57

so its true

Method 2

51 + 72 + (8x + 9) = 180

123 + 8x + 9 = 180

132 + 8x = 180

8x = 180-132

8x = 48

x = 48/8

x = 6

now again you can check by evaluating the value of x in the above expression

Step-by-step explanation:

If p(n)=4n2+4n−6 and q(n)=n2−5n+8.The value of (p−q)(3) will be 26. Option a is correct.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

p(n)=4n²+4n−6 and q(n)=n²−5n+8

Substitute the given values and apply the arithmetic operation as,

(p−q) = (4n²+4n−6) - (n²−5n+8)

(p−q) =3n²-n+2

Put n = 3 for the given conditions,

(p−q)(3) =3(3)² - 3 +2

(p−q)(3) =27-3+2

(p−q)(3) =29-3

(p−q)(3) =26

Thus, if p(n)=4n2+4n−6 and q(n)=n2−5n+8.The value of (p−q)(3) will be 26. Option a is correct.

(2x − 1) (3x^3 + 4x^2 + 2x − 4)

Factor 3x^3 + 4x^2 + 2x − 4 using the rational roots test.

(2x − 1) (3x − 2) (x2 + 2x + 2)

The factorized form of the given polynomial is (2x − 1)(3x − 2)(x² + 2x + 2).

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The polynomial is given in the question, as follows:

6x⁴ + 5x³ − 10x + 4

We have to factor using the rational roots test,

⇒ (2x − 1)(3x³ + 4x² + 2x − 4)

Similarly, factor 3x³ + 4x² + 2x − 4 operates the rational roots test.

⇒ (2x − 1)(3x − 2)(x² + 2x + 2)

Thus, the factorized form is (2x − 1)(3x − 2)(x² + 2x + 2).
