Answer:

The result is 13.3452

It depends on what your teacher wants you to round to.

To the whole number, it would be 13.

To the tenth, it would be 13.3

To the hundredth, it would be 13.35.

To the thousandth, it would be 13.345.

Hope this helps.

Answer:

13.3452, multiply both the numbers,
an estimation would be about 13 since 1.98 is close to 2 and 6.74 is close to 7, but since they aren’t quite there, a 13 would make sense to guess

The option that describes the end behavior of the graphed function is the second one.

f(x) → ∞ as x →-∞

f(x) →∞ as x →∞

For any function y = f(x), we define the end behavior as the behavior of the function as x tends to negative infinity and positive infinity.

If we look at the left side of the graph, we can see that the function goes upwards.

Then we can assume that as x tends to negative infinity, the function tends to infinity (because it keeps going up) this is written as:

f(x) → ∞ as x →-∞

On the right side we can see the same thing, then when x goes to infinity we can write:

f(x) →∞ as x →∞.

So the end behavior of the function is:

f(x) → ∞ as x →-∞

f(x) →∞ as x →∞.

So the correct option is the second one.

Arithmetic progression

Next 3 terms are 15, 18 and 21.

Step-by-step explanation:

The sequence is an arithmetic progression (AP)

Looking at the first few terms of the sequence,

there is an addition of 3 from the current term to the next term.

(Value of addition of 3 is a constant)

Hence,

First blank: 12 + 3 = 15

Second blank: 15 + 3 = 18

Third blank: 18 + 3 = 21

A number cube is a 6 sided die, so the probability of rolling a 3 is 1/6.

Each coin flip is treated as a separate event because the outcome of one flip has no bearing on the outcome of any subsequent flips. List every outcome that each experiment could produce. A coin is flipped after rolling a regular number cube. Flipping four coins.

Okay, so the likelihood of rolling an even number is equal to half. Flipping tells is likewise half, as well. Thus, in its most basic form, this is the answer to the exercise and the likelihood of doing both will be 1/4. An event's probability is always between 0 and 1.

The volume of the cone is  37.68 cm³.

The volume of a cone can be found as follows:

volume of a cone = 1 / 3 πr²h

where

Therefore, let's find the height of the cone using Pythagoras's theorem.

The height of the cone and the radius of the cone are the two legs of the right angle triangle. The slant height of the cone is the hypotenuse of the right angle triangle.  

Hence,

h² = 5² - 3²

h² = 25 - 9

h = √16

h = 4 cm

Hence,

volume of the cone = 1 / 3 πr²h

h = 4 cm

r = 3 cm

The polynomial f(x) = 4x³ + 9x² - 3x - 10 divided by d(x) = x + 2 will give a quotient of 4x² + x - 5 and a remainder of 0 using the synthetic division.

Using the remainder theorem, f(-2) = 0.

d(x) is a factor of f(x).

f(x) = (x + 2)(4x² + x - 5) + 0.

A polynomial is a mathematical expression which have a sum of powers in one or more variables with coefficients. The highest power of the variable in a polynomial is called its degree.

We shall divide the polynomial 4x³ + 9x² - 3x - 10 by x + 2 as follows;

4x³ divided by x equals 4x²

x + 2 multiplied by 4x² equals 4x³ + 8x²

subtract 4x³ + 8x² from 4x³ + 9x² - 3x - 10 will result to x² - 3x - 10

x² divided by x equals x

x + 2 multiplied by x equals x² + 2x

subtract x² + 2x from x² - 3x - 10 will result to -5x - 10

-5x divided by x equals -5

x + 2 multiplied by -5 equals -5x - 10

subtract -5x - 10 from -5x - 10 will result to a remainder 0

The remainder theorem states that if a polynomial say f(x) is divided by x + a, then the remainder is f(-a)

f(-2) = 4(-2)³ + 9(-2)² - 3(-2) - 10

f(-2) = -32 + 36 + 6 - 10

f(-2) = 0

The factor theorem states that: if the polynomial f(x) is divisible by x + a if and only if f(-a)=0

d(x) is a factor of f(x) because f(x) is divisible by d(x)

Therefore, presenting the result from the synthetic division of the polynomial f(x) using the division algorithm, we have; f(x) = (x + 2)(4x² + x - 5) + 0

Here are the shapes and dimensions of each garden space:

Iris Orchid: rectangular, 4x + 2 and x + 5

Sonny Flower: square, 4x + 2

To find the area of each garden space, you will need to use the formula for the area of a rectangle (length x width) or the area of a square (side length x side length). Here is how you would find the area of each space:

Rose Bush: (3x + 1) * (2x + 7) = 6x^2 + 7x + 2x + 7 = 6x^2 + 9x + 7

Iris Orchid: (4x + 2) * (x + 5) = 4x^2 + 9x + 2x + 10 = 4x^2 + 11x + 10

Sonny Flower: (4x + 2) * (4x + 2) = 16x^2 + 32x + 16x + 4 = 16x^2 + 48x + 4

Therefore, the area of the garden space for Rose Bush is 6x^2 + 9x + 7, the area of the garden space for Iris Orchid is 4x^2 + 11x + 10, and the area of the garden space for Sonny Flower is 16x^2 + 48x + 4.

Step-by-step explanation:

putting the value of x in the equation then we simply get..

5×1+15 = 20

The linear equation that is perpendicular to 2x+3y=15 that we wanted to find can be written as:

y = (3/2)*x + 3/2

Remember that a general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Two lines are perpendicular if the product between the slopes is equal to -1.

So if our line must be perpendicular to:

2x + 3y = 15

(we can rewrite that to get):

3y = 15 - 2x

y = (15 - 2x)/3

y = 5 - (2/3)*x

Then we must have that:

a*(-2/3) = -1

a = -1*(-3/2) = 3/2

So the perpendicular line is something like:

y = (3/2)*x + b

We know that our point passes through (1, 3), replacing the values on the equation we will get:

3 = (3/2)*1 + b

3 = 3/2 + b

3 - 3/2 = b

6/2 - 3/2 = b

3/2 = b

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

Some measurements of angles of JKLM and PQRS are given. m∠MJK = (12x+15)°, m∠SPQ = (14x-5)°, m∠JKL = 115°,

m∠JML = (8y + 12)°, m∠PSR = = (13y-18)°.

And we know the quadrilaterals are similar.

Two quadrilaterals are similar, so their corresponding angles are equal.

JKLM and PQRS are shown, where JKLM is similar to PQRS.

So,

m∠JML = (8y + 12) = m∠PSR = = (13y-18)°.

8y + 12 = 13y -18
