how do you solve 821*54 using an area model
Answer:
800 20 1
50| | | |
4 | | | |
pretty much a rectangle with 800 20 1 at the top
50 4 on the side
and split the numbers in the box - i tried to recreate it as much as possible
oh then in each little box you have to multiply the numbers so
50 x 800 = 40,000 in the box
50 x 20 = 1,000 in the next box
50 x 1 = 50 in the next box
4 x 800 = 3,200
4 x 20 = 80
4 x 1 = 4
then you add all of them which would be 44,334
Find the x-intercept and y-intercept of the line. 7x+5y=-15
Answer:
The x-intercept is (-2 1/7, 0).
The y-intercept is (0, -3).
Step-by-step explanation:
To find the y-intercept, substitute x with zero.
To find the x-intercept, substitute y with zero.
Finding the y-intercept by substituting x with zero:
7*0 + 5y = -15
5y = -15
y = -3
The y-intercept is (0, -3).
Finding the x-intercept by substituting y with zero:
7x + 5*0 = -15
7x = -15
x = -15/7
x = -2 1/7
The x-intercept is (-2 1/7, 0).
what is 13q - 9q + 5 = 17
the answer is: q=3
start by combining like terms (13q - 9q) which would leave you with 4q + 5 = 17. subtract 5 from both sides and you're left with 4q = 12. divide by 4 on both side and you get q = 3
Answer:
q=3
Step-by-step explanation:
13q - 9q + 5 = 17
13q - 9q = 17 - 5
4q = 12
4q/4 = 12/4
q = 3

using de moivre's theorem to find square roots of (2-2√ 3 i)
Let z = 2 - 2√3 i. In polar form, we have
[tex]z = |z| e^{i\arg(z)}[/tex]
where
[tex]|z| = |2-2\sqrt3| = \sqrt{2^2 + (-2\sqrt3)^2} = 4[/tex]
[tex]\arg(z) = \tan^{-1}\left(-\dfrac{2\sqrt3}2\right) = -\tan^{-1}(\sqrt3) = -\dfrac\pi3[/tex]
Equivalently,
[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right)[/tex]
Let w be a complex number such that w ² = z. By DeMoivre's theorem,
[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right) \\\\ \implies z^{1/2} = 4^{1/2} \left(\cos\left(\dfrac{-\frac\pi3+2k\pi}{2}\right) + i \sin\left(\dfrac{-\frac\pi3+2k\pi}{2}\right)\right)[/tex]
where k ∈ {0, 1}. So the two square roots of z are
[tex]z^{1/2} = \begin{cases}2\left(\cos\left(-\dfrac\pi6\right) + i\sin\left(-\dfrac\pi6\right)\right) & \text{for }k=0 \\\\ 2\left(\cos\left(\dfrac{5\pi}6\right) + i\sin\left(\dfrac{5\pi}6\right)\right) & \text{for }k=1\end{cases}[/tex]
[tex]z^{1/2} = \begin{cases}2\left(\dfrac{\sqrt3}2 - \dfrac12 i\right) & \text{for }k=0 \\\\ 2\left(-\dfrac{\sqrt3}2 + \dfrac12 i\right) & \text{for }k=1\end{cases}[/tex]
[tex]\boxed{z^{1/2} = \begin{cases}\sqrt3 - i & \text{for }k=0 \\ -\sqrt3 + i & \text{for }k=1\end{cases}}[/tex]

will mark brainliest!!!!!
Answer:
Table:
1: f(x) = 5
2: f(x)= 6
5: f(x) = 9
Points: (1,5), (2,6), and (5,9)
Step-by-step explanation:
1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.
[tex]f(x) = 1 + 4 = 5[/tex] [tex]f(x) = 2 + 4 = 6[/tex] [tex]f(x) = 5 + 4 = 9[/tex]Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.
2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:
[tex](1,5)[/tex] [tex](2,6)[/tex] [tex](5,9)[/tex]Therefore, the points are (1,5), (2,6), and (5,9).

Mr. Alcazar bakes cookies in batches of 60 and batches of 90. If he bakes 6 batches of 60 cookies, how many cookies does he bake?
Answer:
Mr. Alcazar baked 810 cookies.
Step-by-step explanation:
Given that Mr. Alcazar bakes 6 batches of 60 cookies and five batches of 90 cookies, to determine the amount of cookies that he cook, the following calculation must be performed:
(6 x 60) + (5 x 90) = X
360 + 450 = X
810 = X
Therefore, according to the calculation that has been made, Mr. Alcazar baked 810 cookies.

The rectangle below has sides measuring 6cm and 5 cm. What is the area of this rectangle
Answer:30 cm
Step-by-step explanation:
Area is found by two side lengths multiplied together, the two side lengths in the problem are 5cm and 6cm, 5 times 6 is 30, (plus add the measurement) which is 30 cm. :))
The area of the rectangle which has sides that measures 6cm and 5cm is 30 cm²
How to calculate the area of the rectangle?The rectangle has two sides that measures 6cm and 5cm respectively
The formula for calculating the area of a rectangle is length multiplied by width
The area of the rectangle can be calculated as follows
= 6 × 5
= 30 cm²
Hence the area of the rectangle is 30 cm²

Is x-10 a factor of f(x)=5x^3+60x^2+109x+90
Answer:
No
Step-by-step explanation:
Given values are
f(x) = 5x^3+60x^2+109x+90
x = -10.
Given Polynomial is 5x^3+60x^2+109x+90 .
= (90)+(5.x^3)+(60.x^2)+(109.x)
By putting x = (-10) we can rewrite it as
= (90)+(5.(-10)^3)+(60.(-10)^2)+(109.(-10))
= (90)+(-5000)+(6000)+(-1090)
= 0
The remainder of given polynomial is 0.
