Answer:
diagonal is 11.14 cm
Step-by-step explanation:
We start by writing the equation for the width (w) in terms of the length (L):
w = 2 L - 8
from the area = w * L = 62
we replace w in it: w * L = (2 L -8) * L = 62
2 L^2 - 8 L = 62
2 L^2 - 8 L - 62 = 0
extract 2 common factor:
2 (L^2 - 4 L - 31) = 0
Using quadratic formula we get:
[tex]L=\frac{4+/-\sqrt{4^2-4(1)(-31)} }{2} \\L=\frac{4+/-\sqrt{140} }{2}\\L=7.916\\or\\L=-3.916[/tex]
So, we pick the positive answer L = 7.916 cm
Then we now know the with of the rectangle as well:
w = 2 * L - 8 = 2 * 7.916 - 8 = 7.832 cm
Now we estimate the diagonal of the rectangle using the Pythagorean theorem:
[tex]diag=\sqrt{7.916^2+7.832^2}\approx11.1356\,\,cm[/tex]
which rounded to two decimal places is 11.14 cm

Calculate the value of the following determinants: | 1 -1 3 2 5 0 -3 1 2 | and | -1 -8 2 9 1 0 4 1 2 |
Answers
Answer:
1) The determinant = 65
2) The determinant = 152
Step-by-step explanation:
Let us show how to find the determinant of a matrix
You can find the determinant of this Matrix [tex]\left[\begin{array}{ccc}a&b&c\\d&e&f\\g&m&n\end{array}\right][/tex]
by using this rule
Determinant = a(en - fm) - b(dn - fg) + c(dm - eg)
Let us use this rule with the given matrices
1)
[tex]\left[\begin{array}{ccc}1&-1&3\\2&5&0\\-3&1&2\end{array}\right][/tex]
The determinand = 1[(5)(2) - (0)(1)] - (-1)[(2)(2) - (0)(-3)] + 3[(2)(1) - 5(-3)]
= 1[10 - 0] - (-1)[4 - 0] + 3[2 - (-15)]
= 1[10] + 1[4] + 3[2+15]
= 10 + 4 + 3[17]
= 10 + 4 + 51
= 65
The determinant = 65
Let us do the second one
2)
[tex]\left[\begin{array}{ccc}-1&-8&2\\9&1&0\\4&1&2\end{array}\right][/tex]
The determinand = -1[(1)(2) - (0)(1)] - (-8)[(9)(2) - (0)(4)] + 2[(9)(1) - 1(4)]
= -1[2 - 0] - (-8)[18 - 0] + 2[9 - 4]
= -1[2] + 8[18] + 2[5]
= -2 + 144 + 10
= 152
The determinant = 152
Answer:
1. 65
2. 152

Neptune completes 1 ½ turns about its axis each day. How many turns does it complete in 1 week?
Answers
In 7 days it will complete 1.5*7 turns.
1.5*7 = 10.5 turns
The number of turns completed in 1 week is 10.5.
Given that,
Neptune completes 1 ½ turns about its axis each day.We need to determine the no of turns completed in one week.Based on the above information, the calculation is as follows:
As we know that in one week there are 7 days, so the no of turns in one week is
[tex]= 1.5 \times 7[/tex]
= 10.5
Therefore we can conclude that the number of turns completed in 1 week is 10.5.

i'm pretty sure i did it right, but im not sure. i haven't done geometry in like over 2 years.
find the hypotenuse of the triangle with 7 in. and 12 in. as your legs with the Pythgorean theorem (a^2 + b^2 = c^2, c equals the hypotenuse)
use that number you just got (I got [tex]\sqrt{193}[/tex]) and use it as one leg, and 7 in. as the other leg, with d as your hypotenuse
use the Phythagorean theorem again to find d, andddd... you've got your answer!
Length of diagonal 'd' of the right rectangular prism given in the picture will be 14.765 inches.
Pythagoras theorem: Pythagoras theorem is applicable in a right triangle. Pythagoras theorem is given by the expression,(Hypotenuse)² = (Leg 1)² + (Leg 2)²
By applying Pythagoras theorem in right tringle ΔCBE,
(CE)² = (BC)² + (BE)²
(CE)² = 5² + 12²
CE = √169 = 13 inches
Similarly, apply Pythagoras theorem in right triangle ΔDCE,
(DE)² = (CD)² + (CE)²
d² = 7² + (13)²
d² = 49 + 169
d = √218
d = 14.7648
d ≈ 14.765 inches
Hence, measure of diagonal 'd' will be 14.765 inches.

Who to tell if the question is rational or irrational
Answers
An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. Any number that can be written as a fraction or a ratio is a rational number. The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction.

Use the equation below to find T, if W=62, m=4, and a=6
Answers
Answer:
T = 38
Step-by-step explanation:
T = 38 because:
1) Plug in all the variables into the equation
Equation: T = 62 - 4(6)
2) Next, solve the equation. First, do multiplication because of order of operations.
Equation: T = 62 - 24
3) Now just subtract 62 and 24
Equation: 38 = 62 - 24
Therefore, T = 38
