-4(2^3)/2+17
Step 1: do what is in the parenthesis which is two to the square root of three
Step 2: Which then u multiply it which the answer would be 8
Step 3: then you take the -4 and the 8 and you will get -32
Step 4: then you divide -32 and 2 and get -16
step 5; thenget -16 and add 17 which you will get the answer 1
Answer:
Refer below for detailed explanation.
Step-by-step explanation:
Standard equation:
1. ax^2+bx+c=0.
Quadratic formula:
2. x = -b+-sqrt(b^2-4ac)/2a. .
Now two equations to find the factored form through these formulas above.
Through this identifying a,b and c.
ax^2+bx+c=0.
x^2+4x-21=0
Here a=1, b=4, and c= -21
Now applying in the quadratic formula.
x=-4+-sqrt(4^2-4(1)(-21))/2(1)
Now solve it and it becomes
x=3 or x= -7.
Another example :
x^2+3x-4=0
Here a=1, b=3 and c=-4.
X=-3+-sqrt(3^2-4(1)(-4))/2(1)
Now solve it and
x= -4 and x=1
P.s have attached the picture of quadratic formula as well.
Answer: ∆LAW ≅ ∆WKL
By rule - ASA congruence postulate.
Step-by-step explanation:
Given: In ∆LAW and ∆WKL
AW⊥WL and WL⊥KL
therefore, by ASA postulate of congruence
∆LAW ≅ ∆WKL
- ASA postulate says that if two angles and the included side of one triangle are congruent to two angles and the included side of second triangle, then the triangles are said to be congruent.
We have been given that a credit card had an APR of 14.86% all of last year, and compounded interest daily. We are asked to find the effective interest rate of the credit card.
We will use effective interest rate formula to solve our given problem., where
= Annual interest rate in decimal form,
m = Number of times interest is compounded per year,
n = Number of compounding periods the rate is required for.
We need rate for 1 year, so n will be 365 times 1.
Let us convert effective rate in percent.
Therefore, the effective interest rate would be .
The horizontal axis represents variable A which means that variable A is ploted in the x-axis.
Each point is plotted (x, y) (i.e. the first number represents the value of variable A).
Therefore, the mean of variable A is
