Answer:
15 feets, 11.25 inches
Step-by-step explanation:
Given that:
Scale = 1 : 48
Thus means that the model is 1/48 the actual size of the jet
Length of fighter jet = 63feets, 9 inches
Converting the entire length to inches
1 feet = 12 inches
63 feets = (12 * 63) = 756
Lenght of jet = (756 + 9) = 765 inches
1/48 * 765 = 15.9375 ; 15 feets, 11.25 inches
Hence, length of model = 15 feets, 11.25 inches
Answer:
x-2 is a factor of following polynomials:
- b(x) = 3x² + 15x - 42
- d(x) = 3x³ - 2x² - 15x + 14
- e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Step-by-step explanation:
In order to check that which polynomials might have x-2 as a factor, we will put
x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.
So,
a(x) = 6x² - 7x - 5
Putting x = 2
b(x) = 3x² + 15x - 42
c(x) = 2x³ + 13x² + 16x + 5
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Hence,
x-2 is a factor of following polynomials:
- b(x) = 3x² + 15x - 42
- d(x) = 3x³ - 2x² - 15x + 14
- e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Answer:
A) 8x^2 - 14x -15
B)(x + 2) (x + 3)
Step-by-step explanation:
A)
So first you would multiply the two together
8x^2 - 20x + 6x - 15
then simplify
8x^2 - 14x -15
B) so first you would take out how many times x^2 can be put in
(x + 2) (x + 3)
then you would just check to be sure
x^2 + 3x +2x +6
x^2 + 5x + 6
Suppose that a "code" consists of 4 digits, none of which are repeated. (a digit is one of the 10 numbers 0,1,2,3,4,5,6,7,8,9) h

The answer is 5040.
This is permutation without the repetition:
P = n!/(n - r)!
n - the number of choices
r - the number of chosen
We have:
n = 10
r = 4
P = 10!/(10 - 4)!
= 10!/6!
= (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (6 * 5 * 4 * 3 * 2 * 1)
= 10 * 9 * 8 * 7
= 5040
