Answer:
4%
Step-by-step explanation:
Actual length of wire = 5 cm
The measured length of wire = 5.2 cm
We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :
[tex]\%=\dfrac{\text{measured length-actiual length}}{\text{actual length}}\times 100\\\\=\dfrac{5.2-5}{5}\times 100\\\\=4\%[/tex]
So, the required percent error is 4%.

Write an equation in slope-intercept form that passes through (5, -8) and runs perpendicular to y = 5/2x + 4
y= (-2/5)x-6
Step-by-step explanation:
the slope of the line perpendicular the the given line is found by the formula m1.m2= -1 hence m2= -2/5
using the slope-intercept form
y+8= -2/5(x-5) y= (-2/5)x-6

1. What is the formula for Pythagorean Theorem
2. What does the A represent
3. What does the B represent
4. What does the C represent
5. Pythagorean Theorem can be used with what SPECIFIC shape?
6. If A= 4, and B = 5, what is length of the hypotenuse? Show all work
Answer:
The formula is a^2 + b^2 = c^2
Step-by-step explanation:
A and B are legs and C is the hypothunisis.
The theorem is used for triangles.
4^2 + 5^2 = c^2
16 + 25 = c^2
41 = c^2
sqr(41) = sqr(c)^2
c = 6.403124237
Write an equation of the circle with center (-2,5) radius 9
Answer:
(x+2)²+(y-5)² = 81
Step-by-step explanation:
The formula for calculating equation of a line is expressed as
(x-a)²+(y-b)² = r²
(a,b) are the points
r is the radius
Given
Point = (-2,5)
Radius = 9
Substitute
(x-(-2)²+(y-5)² = 9²
(x+2)²+(y-5)² = 81
Hence the required equation is (x+2)²+(y-5)² = 81

what is this(9 + 4) × (8 -7)
Answer:
13
Step-by-step explanation:
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
I hope this helps you :D

Step-by-step explanation:
The value of k using the law of sines is 2.05.
What is a law of sine?Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.
In Triangle JKL
< K J L = 58 degrees
< J L K = 38 degrees.
and, J K = 2.3, J L = k.
As, <KJL + <JKL + <LKJ = 180
58+ 23 + <LKJ = 180
<LKJ = 99 degree.
Using Law of sines
k/ sin K = j/ sin J
k/ sin 99 = 2.3/ sin 58
k- 2.05

(x+6) (x-2) multiply out
Answer:
x² + 4x - 12
Step-by-step explanation:
(x + 6)(x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 6(x - 2) ← distribute parenthesis
= x² - 2x + 6x - 12 ← collect like terms
= x² + 4x - 12
