Make improper fractions.

33/5 - 43/10

Find a common denominator, in this case it is 10.

66/10 - 43/10 = 23/10

This can be simplified to 2 3/10

4. (07.04 MC)

Answer:

11779 ft

Step-by-step explanation:

We are given that

$\theta=23^{\circ}$

Distance between tower and plane,d=5000 ft

We have to find the distance between the plane and bird.

Let x be the distance between bird and plane

We know that

$tan\theta=\frac{perpendicular\;side}{Base}$

Using the formula

$tan23=\frac{5000}{x}$

$x=\frac{5000}{tan23}=11779.3 \approx 11779ft$

Hence, the distance between the plane and bird=11779 ft

Solve the triangle. B = 36°, a = 38, c = 18

vovikov84 [41]

Using cosine law.

b= sqrt(38^2 + 18^2 - 2(38)(18) Cos 36)
using calculator solve.
b = sqrt (1444 + 324 - 1106.75)
b = 25.75

Which real value of m makes the expression undefined M^8+1/4m^2

Soloha48 [4]

Answer:

m = 0

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.

4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value
