Answer:

x = 1  and x = -3

Step-by-step explanation:

if y = f(x) and f(x) = -5, this means y = -5

draw a horizontal line at y = -5 and see write the x values for where the line intersects with the graph.

The x values are:

x = 1  and x = -3

The transformed function is:

g(x) =  (3*(x + 4))² +  (3*(x + 4))

Here we have the function:

f(x) = x² + x

Now we want to apply a translation of 4 units to the left, followed by a horizontal shrink by a factor of 1/3.

First, the translation is written as:

g(x) = f(x + 4)

Now the shink will give:

g(x) = f( 3*(x + 4))

Replacing the actual function we will get:

g(x) =  (3*(x + 4))² +  (3*(x + 4))

According to the given statement the absolute value of just about any complex number Ia + biI seems to be the distance between (a, b) and (0, 0) in the complex plane is √(a² + b²).

After dividing one number by another, the modulo operation yields the remainder or signed remainder of the division. A modulo n seems to be the remainder of something like the Euclidean division on a by n, where an is the dividend and n is the divisor, given two positive numbers a and n.

The modulus operator can be used in a variety of situations. It is frequently used to decrease a randomly generated number to a randomly generated number in a smaller range, and it may also rapidly tell you if one integer is a factor of another.

The modulus of any complex number is its absolute value, regarding which there is a modulus formula. √(a² + b²).

where a and b are integers

Please see the attached file for the complex plane of the provided points (a,b) (0,0).

The separation of two points (x1 ,y1) and (x2 ,y2) will be:

She will earn $924 if she works 38.5 hours this week

The function is given as

w(h) = 24h, if h < 40

w(h) = (36(h-40)+960 h> 40

If she works 38.5 hours this week, then

h < 40

So, we use

w(h) = 24h

This gives

w(38.5) = 24 * 38.5

Evaluate

w(38.5) = 924

Hence, she will earn $924 if she works 38.5 hours this week

The measure of angle RQT is 63°

From the question, we are to determine the measure of angle RQT.

From the diagram,

We can observe that ∠PQS and ∠SQT form a linear pair

Thus,

∠PQS + ∠SQT = 180°

(4x + 15)° + (10x - 3)° = 180°

First, determine the value of x

4x + 15 + 10x - 3 = 180

4x + 10x = 180 - 15 + 3

14x = 168

x = 168/14

x = 12

In the diagram,

∠RQT and ∠PQS are vertically opposite

From the given information,

∠PQS = (4x + 15)°

∴ ∠RQT = (4x + 15)°

Substitute the value of x

∠RQT = (4(12) + 15)°

∠RQT = (48 + 15)°

∠RQT = 63°

Hence, the measure of angle RQT is 63°

Explanation:

[tex]a_1[/tex] = -10 is the first term

d = 17 is the common difference. We add this amount to each term to get the next one. Eg: -10+17 = 7

We want to find the 66th term, so we'll use n = 66

Plug these values into the nth term arithmetic sequence formula below.

[tex]a_n = a_1 + d(n-1)\\\\a_{66} = -10 + 17(66-1)\\\\a_{66} = 1095\\\\[/tex]

The 66th term is 1095

Answer:

The answer is 1095.

66th term = 1095

Step-by-step explanation:

an = a1 + (n − 1)d

= -10 + (66 - 1) (17)

I did it on calculator.

It equals to = 1095

The probability that the length of time will be between 50 and 70 hour is  0.4082.

Height is a simple instance of an event that describes a normal distribution: most people are of medium height, the proportions of people who are taller and shorter than average are roughly equal, and a very small (but still roughly equivalent) proportion of people either are extremely tall or extremely short.

Now, as per the given question;

Let t be the variable representing the length of time (t = 50)

As a result, the mean of the battery is 50 and the standard deviation is 15.

Thus, μ = 50 (mean) σ = 15 (standard deviation)

Now, we must calculate the probability that t is between 50 & 70.

Thus, the probability  P (50 < t < 70)

The z-value will be calculated as;

Z = (t – μ) / σ

Substitute the values,

Z = 50 – 50 / 15

Z = 0

Now, for the time; t = 70

Z = 70 – 50 / 15

Z = 1.33

Thus, the probability is;

P(50 < t < 70) = P(0 < z < 1.33)

So, the area to left of Z

= 1.33 – area to the left of z = 0

= 0.9082 – 0.5

P(50 < t < 70) = 0.4082

Therefore, the probability that the length of time will be between 50 and 70 hours is 0.4082.

The graph represents the given parameter

(a) Evaluate g (-2), g(0), g (3) and g (7)

To do this, we take the function value at the given value of x

The function g(-2) means

x = -2

So, we have

When x = -2, g(x) = -3

This means that g(-2) = -3

The function g(0) means

x = 0

So, we have

When x = 0, g(x) = -3

This means that g(0) = -3

The function g(3) means

x = 3

So, we have

When x = 3, g(x) = 4

This means that g(3) = 3

The function g(7) means

x = 7

So, we have

When x = 7, g(x) = 0

This means that g(7) = 0

On the graph, we have the following values of x at g(x) = 0

x = -3, 1, 5 and 7

Hence, the values of x that solve the equation g(x) = 0 are x = -3, 1, 5 and 7
