Answer:
A & B
Step-by-step explanation:
4x²- 12x + 9 = 5
4x²- 12x + 4 = 0
devided by 4
x²-3x+1=0
x = (3 ± √9-4)/2 = (3±√5)/2
x = (√5+3)/2 or x= (-√5+3)/2
If the hypotenyse of an isosceles triangle is 8 inches, is there enough information to find the length of the legs? If yes, find the length of the legs. Round to the nearest tenth if necessary.
Answer: 5..6 in.
Step-by-step explanation:
Given
Hypotenuse of isosceles triangle is 8 inches
In isosceles triangle two sides are equal
Suppose the other side is x
Using Pythagoras we can write
[tex]\Rightarrow x^2+x^2=8^2\\\Rightarrow 2x^2=64\\\Rightarrow x^2=32\\\Rightarrow x=4\sqrt{2}\approx 5.6\ in.[/tex]
Therefore, the lengths of the legs is 5.6 inches

Laura comprou 870 gramas de carne moida e vai dividir ingualmente em 3 pacotes. Quantas gramas terão em cada pacote?
Answer:
290 gramas
Step-by-step explanation:
Podemos interpretar a questão acima matematicamente como:
3 pacotes = 870 gramas
1 pacote = x
Multiplicação cruzada
3x = 1 × 870 gramas
Divida os dois lados por 3
3x / 3 = 1 × 870 gramas / 3
x = 290 gramas
Portanto, cada pacote conteria 290 gramas de carne moída

Step-by-step explanation:
How do I find the answer
Answer:
x = 95 degrees
Step-by-step explanation:
First find the missing angle next to 142 (we will call it y)
y +142 = 180
subtract 142 from both sides
y = 38 degrees
then we know a triangle must have 180 degrees
so
47+38+x = 180
subtract 47 and 38 from 180
x = 95
hope this helps and makes sense :)

Step-by-step explanation:
Use Desmos graphing calculator
Answer:
x = -2y^2
Explanation Part 1:
It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.
This must mean it's either x = 2y^2 or x = -2y^2
Explanation Part 2:
You can test values into either one to check if it works
Take (-2, 1) for example, doesn't have to be a precise coordinate pair:
First Equation
x = 2y^2
-2 = 2(1)^2
-2 = 2(1)
-2 = 2
DOESN'T WORK!
Second Equation
x = -2y^2
-2 = -2(-1)^2
-2 = -2(1)
-2 = -2
IT WORKS!
The Asian elephant is an endangered species with a current population of 45,000. This species is said to be experinceing a decline of 4.5% per year. After how many years should we expect the Asian elephant poputation ot be approximately 35,746?
Answer:
5 years
Step-by-step explanation:
Given that
The current population is 45,000
The rate of interest in declining would be 4.5% per year
The expected population is 35,746
We need to find out the no of years
Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955
Now
Year 1 = 45,000 × 0.955 = 42,975
Year 2 = 42,975 × 0.955 = 41,041.125
Year 3 = 41,041.125 × 0.955 = 39,194.27
Year 4 = 39,194.27 × 0.955 = 37,430.53
Year 5 = 37,430.53 × 0.955 = 35,746.16
Hence, the no of years would be 5
Misty purchased two pairs of jeans that were originally $24 each, but were on sale for _1 3 off of the total price. How much did she save?
Answer:
the amount saved by her for two jeans is $16
Step-by-step explanation:
Given that
Misty purchased two pairs of jeans that cost $24 each
But they were on sale for one third of the total price
We need to find out the amount save
So, the amount saved is
= $24 × 1 ÷ 3 ×2 jeans
= $16
Hence, the amount saved by her for two jeans is $16
What would this be? Please help.
Answer:
-176
Step-by-step explanation:
Let x = -8
f(-8) = 11 (-8-24) / 2
Simplify the parentheses
f(-8) = 11 ( -32)/2
= 11 (-16)
= 176

If (-10,8) is a point on the terminal side f a angle 0 in standard position what is the value of tan0?
Answer:
The value of the tangent is [tex]-\frac{4}{5}[/tex].
Step-by-step explanation:
Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)
Where:
[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.
[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.
If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]
[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]
[tex]\tan \theta = -\frac{4}{5}[/tex]
