Work out the area of this circle.
Take pi to be 3.142 and write down all the digits given by ur calculator
Answers
Answer:
314.2 cm²
Step-by-step explanation:
The formula for the area of a circle is πr², so since the radius is 10, just multiply 100 × π, which is 314.2, since the problem told you to use 3.142 for π.

Which trigonometric identity is given by the formula adjacent side/opposite side?
A. tan
B. cot
C. sin
D. cos
Answers
Answer:
cot= adjacent side/opposite side
Option B is correct.
Step-by-step explanation:
We need to identify trigonometric identity which is given by the formula adjacent side/opposite side
The trigonometric identity for tan is
tan= opposite side/adjacent side
But We are given adjacent side/opposite side
Since cot is inverse of tan so, formula of cot is:
cot= adjacent side/opposite side
Option B is correct.

Answer:
y = (5/2)x - 5
Step-by-step explanation:
SLOPE:
The slope is rise over run, and in this case (thanks to the graph), we can do the [difference of y] / [difference of x] pretty easily. This is 5 / 2
Y-INTERCEPT:
Y-intercept is simple: where the line touches the y-axis. This happens at y = -5.
Therefore, the equation y = (5/2)x - 5

Anna's college tuition payment is automatically
withdrawn from a separate checking account used only
to pay tuition. At the beginning of the year, the balance
in this account was $13,287.48. After withdrawals each
month for a year, the balance is $1,449.84. How much is
Anna's college tuition payment each month? Estimate to
show that your answer is reasonable.
Answers
Answer: $986.47
Step-by-step explanation:
The total tuition fee for the year is;
= 13,287.48 - 1,449.84
= $11,837.64
The payment per month will therefore be;
= 11,837.64/12 months
= $986.47
the sum of two numbers is 16. their difference is 1. what is the product of the two numbers
Answers
Answer:
The product of the numbers is 63.75
Step-by-step explanation:
Let the numbers be x and y
x + y = 16
x -y = 1
Adding both together
2x = 17
x = 17/2
x = 8.5
Recall
x -y = 1
8.5 - y = 1
y = 8.5 - 1 = 7.5
Their product is xy
so we have 7.5 * 8.5 = 63.75

1. Parallelogram WXYZ is shown on the coordinate plane ect...
Added photo plz help!!
Answers
Answer:
Step-by-step explanation:
12.718 units
Step-by-step explanation:
The coordinates of the vertices of parallelogram WXYZ are given to be W(0,-1), X(4,0), Y(3,-2) and Z(-1,-3).
So, the perimeter of the parallelogram will be 2(WX + XY) {Since opposite sides of parallelogram are same in length}
Now, length of WX = units, To find the units click this link :
https://tex.z-dn.net/?f=%5Csqrt%7B(-1)%5E%7B2%7D%20%2B%204%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B17%7D%20%3D%204.123
And, length of XY = units, To find the units click this link :
https://tex.z-dn.net/?f=%5Csqrt%7B(4-3)%5E%7B2%7D%20%2B%20(0-(-2))%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B5%7D%20%3D%202.236
Therefore, the perimeter of the parallelogram WXYZ = 2(4.123 + 2.236) = 12.718 units. (Answer)

Step-by-step explanation:
Make the number that is equal to x be on the side of the x, then multiply those to values.
x = -6
x= 5/2
(x + 6)*(x - 5/2)
Now, distribute the x to the x and the negative 5/2, and add that to 6 distributed to x and negative 5/2. Simplify.

56 mm = 5.6 cm since there are 10 mm in a cm, so we divide by 10 to go from mm to cm.
Since the diameter is 5.6 cm, this means 12 such cans lead to 12*5.6 = 67.2 cm of length needed to house 12 cans along this row.
Similarly, if we had 6 cans along each column, then 6*5.6 = 33.6 cm is needed for this
The diagram below shows what I mean. This diagram is a top-down view of the box. In other words, it's a birds-eye view.
The last dimension we need to take care of is the height of the box. That would be 2*5.6 = 11.2 cm since there are 2 cans along the height
Therefore, the smallest box possible has dimensions of 67.2 cm by 33.6 cm by 11.2 cm
You could have bigger boxes of course, though you'll need to place cushions inside so the cans don't rattle around. The smallest box dimensions listed above are ideal to avoid wasting too much cushion material (you'll still may need some form of cushion though just not as much).
A rectangular piece of metal is 9 in. longer than it is wide. Squares with sides 3 in. long are cut from the four corners, and the flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 80 in. cubed?
Answers
Step-by-step explanation:
Let the width be = w
The length will be = w+9
And height h = 3 inches ( side of square =3 in)
Volume = l x w x h
According to question
[tex]80 = w(w+9)3\\3w^2+27w-80=0[/tex]
So, this equation indicates that the volume of the box is 80 in.

2 rectas se cortan formando 4 ángulos iguales ¿cuanto mide cada uno?
Answers
Answer:
Cada ángulo igual es recto, es decir, mide 90°
Step-by-step explanation:
Intersección de dos rectas
Cuando dos rectas no paralelas se intersectan, forman en el punto de corte 4 ángulos iguales de a pares, es decir, dos pares de ángulos congruentes.
La suma de todos los ángulos formados es invariablemente 360°.
En general, siendo a y b dos ángulos adyacentes formados por el cruce, se cumple que:
a + b = 180°
Y la suma de todos los ángulos es el doble de lo anterior:
2a + 2b = 360°
Si todos los ángulos son iguales, a=b, entonces:
4a = 360°
a = 90°
Cada ángulo igual es recto, es decir, mide 90°
