Which is equivalent to log1/2462

Mathematics
1 answer:
egoroff_w [7]3 years ago
7 0

Answer:

B

Step-by-step explanation:

Given the expression:

log_{1/2} 462

we want to find an equivalent expression.

Change of base formula:

log_{a} b = \frac{log b}{log a}

where log means logarithm with base 10, also known as common logarithm.

Then, the expression of the problem is transformed into:

log_{1/2} 462 = \frac{log 462}{log (1/2)}

I’m begging for help!! ASAP
kompoz [17]

This is an awful question.  They mean to say  the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event.  Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.

Inverse variation means the product is a constant, we'll call it k.

ht = k

When h = 1 hour t=6 minutes

(1)(6) = k

k = 6  (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)

Decreasing her time by one minute means t = 6 - 1 = 5.  We solve for h.

ht = k

h = k/t = 6/5 = 1.2 hours

Answer: 1.2 hours, second choice

Find the volume and surface area of the square pyramid
Montano1993 [528]

The volume and surface area of the pyramid will be 392 / 3 cubic units and 189 square units. Then the correct option is A.

The complete question is attached below.

<h3>What is the volume and surface area of the pyramid? </h3>

Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

The surface area of the pyramid will be

SA = 2(1/2 × B × K) + 2(1/2 × L × K) + (L × B)

Then the volume will be

V = (7 × 7 × 8) / 3

V = 392/3 cubic units

Then the surface area will be

SA = 2(1/2 × 7 × 10) + 2(1/2 × 7 × 10) + (7 × 7)

SA = 189 square units

Then the correct option is A.

More about the volume and surface area of the pyramid link is given below.

Find the point below that lies on the line y-5=7(x-6).
MrMuchimi

Answer:

(6,5)

Step-by-step explanation:

The equation is in point slope form: y-y_1=m(x-x_1)

'm' is the slope.

(x1, y1) is the point used to create the equation.

The number 6 replaces the x1 spot.

The number 5 replaces the y1 spot.

So a point that lies on the line should be (6,5).
