(Quadratic Formula) (Irrational level 1)

Mathematics
1 answer:
Leni [432]3 years ago
7 0

Answer:

(-11 +/- sqrt 21) /  10

or

-0.64 , -1.56 to the nearest hundredth.

Step-by-step explanation:

9v^2 + 11v + 5 = 4v^2

5v^2 + 11v + 5 = 0

Using the quadratic formula:

v  = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5

= (-11 +/- sqrt 21) /  10

= -0.64 , -1.56 to the nearest hundredth.

Area of rectangle

21m^2

Area of one triangle

divide length of 7 by 2 (3.5)

gives you length b (unknown side that is not hypotenuse)

then multiply by width of triangle (4)

3.5 * 4 = 14

and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.

add the area of the rectangle

14+21= 35

35m^2

Question 11 point(s) Jared made Ask Your Teacher cups of snack mix for a party. His guests ate Ask Your Teacher of the mix. How
liq [111]

Answer:

8\frac{1}{2} cups

Step-by-step explanation:

To determine the quantity of snack mix Jared guest ate, we multiply the quantity of snack mix the guest ate by the quantity of snack mix Jared made. i.e we determine \frac{2}{3}of12\frac{3}{4} by multiplying both fractions together

quantity of snack mix Jared guest ate = \frac{2}{3}of12\frac{3}{4}=\frac{2}{3}*12\frac{3}{4}=\frac{2}{3}*\frac{51}{4}=\frac{17}{2} =8\frac{1}{2}
