The missing value to the nearest hundredth using inverse trigonometric function is 67.11°

Let us say

Cos x = 7/18

x will be the inverse of cosine of (7/18)

The inverse trigonometric functions are the inverse functions of the trigonometric functions and are used to obtain an angle from any of the angle's trigonometric ratios.

x = cos⁻¹ (7/18)

x = 67.11°

Hence, the missing value to the nearest hundredth is 67.11°.

Answer:

(x+2) is a factor of P(x)

Step-by-step explanation:

Determine if x + 2 is a factor of p(x) = x ^4 + 3x^ 3 + 4x ^2 - 8

[tex]p(x) = x ^4 + 3x^ 3 + 4x ^2 - 8[/tex]

To determine (x+2) is a factor , we set x+2=0 and solve for x

[tex]x+2=0 , x=-2[/tex]

then we replace x with -2 in p(x)

[tex]p(x) = x^4 + 3x^ 3 + 4x ^2 - 8[/tex]

[tex]p(-2) = (-2)^4 + 3(-2)^ 3 + 4(-2)^2 - 8[/tex]

[tex]p(-2) = 16-24+16- 8=0[/tex]

WE got p(-2)=0 , so (x+2) is a factor of P(x)

Answer:

A

Step-by-step explanation:

The smaller of the two possible angles used is;

θ = 15.92°.

We are given;

Range of pass; R = 7.75 m

Speed; u = 12 m/s

Formula for range is;

R = [u²sin (2θ)]/g

Where; θ is the angle at which the ball was thrown.

Thus;

7.75 = 12² × (sin(2θ))/9.8

(sin(2θ)) = (7.75 × 9.8)/12²

(sin(2θ)) = 0.5274

2θ = sin^(0.5274)

2θ = 31.83

θ = 31.83/2

θ = 15.92°

Now, if we assume that this angle is to the vertical, it means the angle to the horizontal is;

90 - 15.92 = 74.08°

In conclusion, the two possible angles are 15.92° and 74.08°.

"  A DMP allows you to deposit a set amount of money with a credit counseling organization each month, which is then strategically dispersed to your various creditors "

" DMPs are designed to help consumers work off their debt as quickly as possible by leaving these decisions largely to credit counseling professionals "

Before sending monthly payments to the organization handling your DMP, confirm with your creditors that they have in fact accepted the plan.

Before you make any payments to the organization handling your DMP (debt management plan) you should confirm with your creditors that they have accepted the plan.

A Debt Management Plan is a laid-out framework for settling debts that is coordinated by a credit counseling organization. A certain amount of money is deposited with these organizations that help the debtor to offset his bills in a strategic manner.

So, before making any payments to the organization handling your DMP (debt management plan) you should confirm with your creditors that the plan for repayment is acceptable by them.

Answer:

[tex]a_n = a_{n-1}-13.8[/tex]

Step-by-step explanation:

The recursive rule for the arithmetic sequence is given by:

[tex]a_n = a_{n-1}+d[/tex]          .....[1]

where, d is the common difference of two consecutive terms.

Given the sequence:

−7.4, −21.2, −35, −48.8, −62.6

This is an arithmetic sequence

Here, first term[tex](a_1)[/tex] = -7.4 and d = -13.8

Since,

-21.2+7.4 = -13.8,

-35+21.2 = -13.8 ans so on...

Substitute the given value in [1] we have;

[tex]a_n = a_{n-1}+(-13.8)[/tex]

⇒[tex]a_n = a_{n-1}-13.8[/tex]

Therefore, the recursive rule for the sequence is, [tex]a_n = a_{n-1}-13.8[/tex] and [tex]a_1[/tex]= -7.4

The recursive rule for the sequence is [tex]\rm a_{n} = a_{n-1} -13.8[/tex]  and [tex]\rm a_{1}[/tex] = -7.4.

The recursive rule refers to the first term of the sequence and describe  

the relation to the preceding term with the recursive equation.

The recursive formula for the arithmetic sequence is as follows

[tex]\rm a_{n} = a_{n-1} + d[/tex]

where [tex]\rm a_{n}[/tex] is the nth term and d is a common difference

The arithmetic sequence is given as

−7.4, −21.2, −35, −48.8, −62.6

[tex]\rm a_{1}[/tex] = -7.4 (first term)

d = -21.2+7.4 = -13.8,

d = -35+21.2 = -13.8

Substitute the given value, we get

[tex]\rm a_{n} = a_{n-1} + d[/tex]

[tex]\rm a_{n} = a_{n-1} -13.8[/tex]

Hence, the recursive rule for the sequence is [tex]\rm a_{n} = a_{n-1} -13.8[/tex]  and [tex]\rm a_{1}[/tex] = -7.4.

After calculating Peter's earnings from working on 6 houses, the remaining amount from his total paycheck indicates that he worked for 25 hours at his hourly wage of $6.

To determine how many hours Peter worked when he received a paycheck for $210, we need to consider his earnings per house and his hourly wage. Peter makes $6 per hour for doing yard work plus $10 for every house he does work on.

First, we calculate the total earnings from the houses he worked on. Since he did yard work for 6 houses, we multiply 6 houses by $10 per house:

6 houses times $10 per house = $60

Now, subtract the total earnings from houses from his total paycheck to find out how much he earned from hourly wages:

$210 (total paycheck) - $60 (earnings from houses) = $150 (earnings from hourly wage)

$150 / $6 per hour = 25 hours

So, Peter worked 25 hours doing yard work.

Step-by-step explanation:

Answer:

Option a is right.

Step-by-step explanation:

Both standard deviation and range are used as measures of dispersion.  These show the deviations of the data within.

While range is maximum -minimum, the std deviation is the square root of variance and variance is the average of the sum of squares of each entry from the mean.

While range depends only on max and min the std deviation depends on each entry of the sample. Hence std deviation is a better measure.

a. the standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the​ observations, whereas the range considers only the largest and smallest ones.

To solve the problem we will first name all the points given to us, and then we will find ∠O, and then we will find the value of x.

The value of x is 22°.

Given to us

Looking at the diagram below,

In ΔAOB

OA =  OB = R, the radius of the circle O,

therefore, the ΔAOB is an isosceles triangle, with OA, OB as the congruent sides and AB as the base of the triangle.

Thus, ∠OAB = ∠OBA = 56°

Sum of all the angles of a triangle = 180°

∠O + ∠AOB + ∠OBA = 180°

We know ∠AOB = ∠OBA, therefore,

∠O + 2(∠AOB) = 180°

∠O + 2(56°) = 180°

∠O = 68°,

In ΔOBC,

BC is the tangent to the circle O, therefore,

∠OBC = 90°

Sum of all the angles of a triangle = 180°

∠O + ∠OBC + ∠OCB = 180°

68° + 90° + ∠OCB = 180°

∠OCB = 180° - 68° - 90°

∠OCB = 22°

Hence, the value of x is 22°.

Now, c(3)=45

This means:

c(7)=257

This means that:

[tex]49a+7b+c=257----------------(2)[/tex]

and c(12)=792

This imply:

[tex]144a+12b+c=792-------------------(3)[/tex]

On subtracting first equation from second we get:

[tex]40a+4b=212------------(4)[/tex]

and on subtracting second equation from third we get:

[tex]95a+5b=535-----------(5)[/tex]

Now on multiplying equation (4) by 5 and equation (5) by 4 and subtracting both equation we get:

a=6

Putting value of a in equation (4) we get:

b= -7

and putting the value of a and b in equation (1) we get:

c=12
