Decide weather a triangle could have the given angles measures explain your responds 140,70,186

1 answer:

4 0

You can’t have a triangle with the given angles cause 140+70+186=396 while 180 must be the amount measure of all 3 angles

What is base in mathametics

Art [367]

The most common base used today is the decimal system which means 1 to 9.
The binary system is base two and it only uses the numbers 1 and 0. It does not go over 1. So base 5 is a number system that doesn’t go over four. It’s a little hard to understand until you do some questions relating to it.

Solve each system by substitution. Y= -3x + 4 Y= 4x - 10

tatyana61 [14]

Answer:

Step-by-step explanation:

Y= -3x + 4..........(1)

Y= 4x - 10...........(2)

Substituting (1) into (2)

-3x + 4 = 4x - 10

-3x - 4x = -10 - 4

-7x = -14

x = -14/-7

x = 2

Putting x in (2)

y = 4(2) - 10

y = 8 - 10

y = -2

According to the rational root theron what are all the potential roots of f(x)=9x^4-2x^2-3x+4

Viefleur [7K]

Answer:

Potential roots: $\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1$

Step-by-step explanation:

Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form

± $\frac{FactorsOfa_{0}}{FactorsOfa_n}$

Where

a_n is the number before the highest power of the polynomial, and

a_0 is the constant in the polynomial

From the polynomial shown, we have a_n = 9 and a_0 = 4

The factors of 9 are 9, 3, 1

and

The factors of 4 are 4,2,1

So, if there are any rational roots, they would be:

± $\frac{FactorsOfa_{0}}{FactorsOfa_n}$

± $\frac{9,3,1}{4,2,1}$

Which is ± 9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1

$\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1$
