antiseptic1488 [7]

Idk if this wil help but...



Let speed of Matthew be X yards/min  Speed of Lowe = 3X yards/min.


Distance covered by Matthew in 30 minutes = 30X


Distance covered by Lowe in 30 minutes = 30(3X)= 90X


90X = 30X + 1200       X = 20 yards/min

Let speed of Matthew be X yards/min  Speed of Lowe = 3X yards/min.


Distance covered by Matthew in 30 minutes = 30X


Distance covered by Lowe in 30 minutes = 30(3X)= 90X


90X = 30X + 1200       X = 20 yards/min

Answer:

S 75°E

S 55°E

Step-by-step explanation:

Take the law if sines of a triangle:

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

Where,

a = 28 miles

B = 25°

b = 12 miles

First solve for A, using the law of sines:

\frac{a}{sinA} = \frac{b}{sinB}

\frac{28}{sinA} = \frac{12}{sin25}

Cross multiply:

28 sin25 = 12 sinA

11.83 = 12 sinA

Sin A = \frac{11.83}{12}

Sin A = 0.986

A = sin^-^1(0.986)

A = 80.44 degrees

Since A = 80.44° find A supplement, A`:

A` = 180 - 80.44

A` = 99.56°

If A` + B < 180°, find C.

Thus,

A` + B = 99.56 + 25 = 124.56

We can see that A` + B < 180

Find C:

C = 180 - (80.44+25) = 74.56° ≈ 75°

C` = 180 - (99.56+25) = 55.44° ≈ 55°

Rewrite in bearing form:

S 75°E

S 55°E

Write each polynomial function in standard form , classify it by degree and determine the end behavior of its graph Y=12-x^4
Dmitry_Shevchenko [17]
In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0 

End behavior: 
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
