PLEASE HELP ME I NEED 4 ANSWERS !!!!!!!!!! a) Fill in the gaps to factorise the expression below.
3x² + 16x + 5 = (3x + −)(x + −)
b) Use your answer to part a) to solve 3x² + 16x + 5 = 0

The formula for the area(A) of the sector is,

Given:

Therefore,

Simplify

Hence,

Let x represent the number of math problems that you completed.

Let y represent the number of biology problems that you completed

From the information given,

You completed a total of 15 problems. This means that

x + y = 15

If each math problem takes 5 minutes to complete, it means that the time to complete x math problems is 5 * x = 5x

If each biology problem takes 3 minutes to complete, it means that the time to complete y biology problems is 3 * y = 3y

If you spent 51 minutes working on your homework problems for math and

biology, it means that

5x + 3y = 51

Thus, the system of equations is

x + y = 15

5x + 3y = 51

Notice that the parent function of y is:

Now, recall that a function h(x) translated n units to the left is represented by:

translated m units up :is represented by

reflected across the x-axis :is represented by

vertically compressed by a factor of 1/k :is represented by

Therefore, y is f(x) translated 3 units to the left, reflected over the x-axis, vertically compressed, and translated 2 units up.

y is its parent function translated 3 units to the left, reflected over the x-axis, vertically compressed, and translated 2 units up.

Surface area of a sphere: 4 π r^2

Where:

r = radius = d/2 = 14/2 = 7

Replacing

SA = 4 π 7^2 = 4 π 49 = 196π cm2

Answer:

2.5×10^-11

Step-by-step explanation:

Put the point in the middle of 2 and 5 and count how many times you need to get there ...

like 0.05 to put point after 5 you have to jump 2 steps so it is 5×10^-2.

the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

We are given the function as:

BSA = √( w h / 3600)

where:

h = height

w = weight

BSA = body surface area

1) Now, for w = 68 kg and BSA = 1.9, we get the height as:

1.9 = √( (68) h / 3600)

3.61 = 68 h / 3600

12,996 = 68 h

h = 12996 / 68

h = 191.12 cm

h ≈ 191 cm

2) for h = 165 cm and BSA = 2.2, we get the weight as:

2.2 = √( w (165) / 3600)

4.48 = 165 w / 3600

17424 = 165 w

w = 17424/ 165

w = 105.6 kg.

w ≈ 106 kg

Therefore, we get that, the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

he graph fo the function cnan be obtained by graph of cube root of x.

If we shift the graph of cube root by x by one unit left then then function changed to,

If the obtained graph shrink vertically by a factor of 3/4 then graph changed to function,

This is the requied function for which we need the graph.

So graph can be obtained by horizontal shift of 1 unit to left, shrink by a factor of 3/4 and there is no vertical shift and graph will not flip over any axis.

Thus answer is, All statements are true.

⇒In this case what is in the brackets is being treated as being the term . so this means that if we are to expand then we expand the whole term in full detail.

Consider the given radical,

Factorize the number,

Consider the following properties,

Then the radical can be simplified as,

Thus, the radical is simplified as,

Step-by-step explanation:

Let use the following rules to construct a polynomial,

Rule 1:

If r is a zero of some polynomial, f(x), then

[tex](x - r)[/tex]

is a factor of the polynomial

We first know that one of our zeroes are real, which is 0.

So since r=0

[tex](x - 0) = x[/tex]

is a factor

However, since the root ,0, has a multiplicty of 4, that basically means we have 0 as a root 4 times or basically we multiply the factor 4 times.

[tex]x \times x \times x \times x = x {}^{4} [/tex]

This leads to an another rule:

If a polynomial has a zero, r that has a multiplicty of k,

we represent the factor as

[tex](x - r) {}^{k} [/tex]

where k is all integers greater than 0.

So to reinforce myself, since 0 has a multiplicty of 4, we have

[tex](x - 0) {}^{4} = {x}^{4} [/tex]

So our first factor is

[tex] {x}^{4} [/tex]

Part 2: Complex Zeroes.

When dealing with complex zeroes, we must note this rule.

if (a+bi) is a zero of some polynomial, p then its conjugate (a-bi) is a factor as well.

So if 3-2i is a factor, then

3+2i is a factor as well.

Using Rule 1, our factors now become

[tex](x - (3 + 2i))[/tex]

and

[tex](x - (3 - 2i))[/tex]

So our factors are

[tex] {x}^{4} (x - (3 - 2i)(x - (3 + 2i))[/tex]

To simplify use FOIL Method,

[tex] {x}^{4} ( {x}^{2} - x(3 + 2i) - x(3 - 2i) + 9 - 4 {i}^{2} )[/tex]

[tex] {x}^{4} ( {x}^{2} - 6x + 13)[/tex]

[tex] {x}^{6} - 6 {x}^{5} + 13 {x}^{4} [/tex]

So our polynomial is

[tex] {x}^{6} - 6 {x}^{5} + 13 {x}^{4} [/tex]

The probability she will need to attend more than 3 try-outs is 0.7049.

The probability of an actress getting a job after a tryout is 0.11.

The actress wants to keep trying out for new jobs until she gets offered one.

The number of trials necessary for success in a series of independent trials follows a geometric distribution with parameter p, where p is the probability of success in a single trial.

The probability mass function is given as:

[tex]P(X=k)=q^{k-1}p[/tex] where k = 1, 2, 3

We have p = 0.11

q = 1 - 0.11 = 0.89

If X is the number of tryouts,

[tex]P(X=k)=q^{k-1}p\\P(X=k)=(0.89)^{k-1}(0.11)[/tex]

[tex]P(X\leq r)=1-q^r\\P(X\leq r)=1-(0.89)^r[/tex]

Therefore, the probability that she will need to attend more than 3 try outs will be:

P = P( X > 3 )

P = 1 - P( X ≤ 3 )

P = 1 - [ 1 - 0.89³ ]

P = 1 - 1 + 0.89³

P = 0.704969

P = 0.7049

The slope of line passing through the pair of points (4,3) and (2,2) is 1/2.

Slope is simply expressed as change in y-values over the change in x-values.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1( 4,3 )

Point 2( 2,2 )

Slope m = ?

Plug the given coordinates into the slope formula and solve for m.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 2 - 3 )/( 2 - 4 )

Slope m = ( -1 )/(-2 )

Slope m = ( 1 )/( 2 )

Slope m = 1/2

Therefore, the slope of the line segment with the given coordinates is 1/2.

The Simple interest after three month $423.70

What is Simple Interest ?

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.

If she deposits $366 in the account and you receive interest, you must first calculate the interest for the current year before adding the sum to calculate the interest for the following month.

for instance, deposit plus interest equals the new amount for month one, month one amount plus interest equals amount for month two, and month two amount plus interest equals amount for month three.

The total would thus be $423.70 for the following month:

month 1

366+ (366*.05)=x

366+18.3=x

month 2

384.30+(384.30*.05)=x

384.30+19.22=x

month 3

403.52+(403.52*.05)=x

403.52+20.18=x

423.7 = x

Thus, total amount then would be $423.70
