have? *
2x2 + 7x – 3 = 0
Answer:
2 solutions
Step-by-step explanation:
Well to find out how many solutions it has, you have to find the discriminant:
b^2 - 4ac
a = 2
b = 7
c = -3
Discriminant = 49 + 24 = 73
Discriminant is > 0 so there are 2 solutions

А.
Solution:
Answer:
340 units^2
Step-by-step explanation:
B=(8)(5)=40
40*2=80
h=10 and P=2(5)+2(8)=10+16=26
80+(10)(26)=80+260=340
Therefore, 340 units^2

One of the five cards is chosen at random. Find the probability of choosing a card with a number that
is a six. Write answer as a simplified fraction number, No decimals or percents:
Answer:
Zero.Step-by-step explanation:
Well, assuming that the cards are numbered 1, 2, 3, 4 and 5, then the probability of getting 6 is zero, because there's no card with such number.
Remember that a simple probability is a ratio between the possible events and the total number of outcomes. In this case, the total number of outcomes is 5 and the events are zero, because there's no card with 6.

What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?
(6, 31)
(−6, 31)
(6, −31)
(−6, −31)
Answer:
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]
Step-by-step explanation:
To find the x-coordinate of the vertex of a quadratic function, we can use the formula:
[tex]x=\frac{-b}{2a}[/tex]
We are given the function [tex]f(x)=x^2-12x+5[/tex]
In this function, [tex]a=1[/tex] and [tex]b=-12[/tex]
Now we can input these values into our formula
[tex]x=\frac{-(-12)}{2(1)} \\\\x=\frac{12}{2} \\\\x=6[/tex]
This means that the x-value of the vertex is located at [tex]x=6[/tex]. To find the other half of the coordinate pair, we can now plug [tex]x=6[/tex] into the given function
[tex]f(6)=(6)^2-12(6)+5\\\\f(6)=36-72+5\\\\f(6)=41-72\\\\f(6)=-31[/tex]
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]

Answer:
The angle is "27 and 63".
Step-by-step explanation:
Let A and B are two angles, in which A is " [tex]\frac{1}{2}[/tex] " complementary angles and B be is another complementary angle.
Condition of complementary angle :
[tex]A+B =90 ......(i)[/tex]
Solution:
[tex]\ A = \ 3B - 18 \\\\ \ put \ the \ value \ of \ A \ in \ equation.....(i) \\\\ \ Equation: \\ \\\Rightarrow \ A\ +\ B \ =\ 90 \\\\\Rightarrow \ 3B\ -\ 18 \ + \ B \ = \ 90 \\\\\Rightarrow \ 4B \ = \ 90 +18 \\\\\Rightarrow \ 4B = 108 \\\\ \Rightarrow B = \frac{108}{4} \\\\ \Rightarrow B \ = \ 27\\[/tex]
[tex]\ put \ the \ value \ of \ B \ in \ equation (i).\\\\ \ Equation: \\\\\Rightarrow A+B=90\\\\\Rightarrow A+27=90\\\\\Rightarrow A=90-27\\\\\Rightarrow A= 63[/tex]
