Which is the equation of a line with a slope of -1/3 and a Y intercept at (0,1)
Len [333]

Answer:

y = -1/3x + 1

Step-by-step explanation:

substitute the given values in y = mx + b where m is the slope and b is the y-intercept

y = -1/3x + b

at point (0, 1)

1 = -1/3 × 0 + b

1 = 0 + b

b = 1

Find the volume of the prism.
Zigmanuir [339]

Answer:

The correct answer is first option.  270 m³

Step-by-step explanation:

Formula:

Volume of prism = Base area * Height

Area of triangle = bh/2  where b - base and h - height

From the figure we can see that height of prism = 36 m

Base is a right angled triangle with base 5 m and height = 3 m

<u>To find the Base area</u>

Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5

<u>To find the volume of prism</u>

Volume = Base area * height = 7.5 * 36 = 270 m³

Therefore the correct answer is first option . 270 m³

A $17,000 T-bill is purchased at a 2.75% discount rate for 20 weeks. Find the effective rate of interest to the nearest hundredt
katen-ka-za [31]
Note: 20 weeks = 20/52 or 5/13 of a year.

Let E = effective rate of interest

E = [1 + (r/m)]^m - 1 where r is the nominal (annual ) advertised rate; m is the number of compounding periods/year.

Let r = 0.0275

Let m = 5/13

Plug into formula and do the math.
