Find the value of the trigonometric ratio. Simplify the ratio if possible.

Mathematics
1 answer:
sweet [91]3 years ago
3 0

Step-by-step explanation:

Given that,

BC = 8

Ac = 15

We can find AB using the pythagoas theorem.

AB=\sqrt{AC^2+BC^2}\\\\=\sqrt{15^2+8^2}\\\\AB=17

We know that,

\cos\theta=\dfrac{B}{H}, B is base and H is Hypotenuse

\cosB=\dfrac{8}{17}

Hence, this is the required solution.

Solve the equation<br> 7h-5(3h-8) = 72
frosja888 [35]

Answer:

h = -4

Step-by-step explanation:

7h-5(3h-8) = 72

Distribute

7h - 15h +40 = 72

Combine like terms

-8h +40 = 72

Subtract 40 from each side

-8h+40-40 = 72-40

-8h = 32

Divide each side by -8

-8h/-8 = -32/-8

h = -4

A line passes through the point (1,-3) and has a slope of -7. Find the equation of the line.
Anon25 [30]

Answer:

y = -7x+4

Step-by-step explanation:

We can use the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

We know the slope

y = -7x+b

We have a point to substitute in for x and y

-3 = -7(1) +b

-3 = -7+b

Add 7 to each side

-3+7 =b

4 =b

We can substitute this back into

y = -7x+b

y = -7x+4

MULTIPLE CHOICE A thermometer is
pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

  • Thermometer accuracy = ±2°F
  • Thermometer reading = 17°F

<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :

  • Thermometer reading - thermometer accuracy

  • 17 - 2 = 15°F

<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :

  • Themometer reading - thermometer accuracy

  • 17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
