If r = 4 and a6 = 192, what is the first term of the sequence?

1 answer:

5 0

The first term is a and each time we multiply we get a,4a,16a,64a...The sixth term in terms of a is 1024a so we can set the equation 1024a=192 solving for a we get 3/16.

The measure of an angle is five times the measure of its complementary angle. What is the measure of each angle?

GalinKa [24]

Answer:

150 degrees

Step-by-step explanation:

Let the supplement = x
So the angle you want is 5x
Then [x + 5x] = 180 because they are supplementary.
Solving. 6x = 180. Then x = 30.
So the angle is 5x = 5×30 = 150 degrees

Which of the following is the solution to the system of equations?

drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

$\frac{5}{4} = 2 - \frac{3}{4}$

y = 3x - 1

$\frac{5}{4} = 3 \times \frac{3}{4} - 1$

$\frac{5}{4} = \frac{9}{4} - \frac{4}{4}$

Hope this helps ^-^

Alexis is knitting a blanket 2 meters long. Every 2 decimeters, she changes the color of the yarn to make stripes. How many stri

IgorC [24]

Answer:

There are 10 stripes in the blanket.

Step-by-step explanation:

We are given the following in the question:

Length of blanket = 2 meters

1 meter = 10 decimeter

Length of blanket in decimeter =

$2\times 10 = 20\text{ decimeters}$

Change of color = Every 2 decimeters.

Number of stripe =

$=\dfrac{\text{Length of blanket}}{\text{Length of change of color of stripe}}\\\\=\dfrac{20}{2} = 10$

Thus, there are 10 stripes in the blanket.

Question is not well presented

The parabola y=x² is scaled vertically by a factor of 1/10.

What is the equation of the new parabola?

Answer:

The equation of the new parabola is 0.1x²

Step-by-step explanation:

Given

Parabola: y = x²

Scale = 1/10 = 0.1

The interpretation of this question is that; there's a need to scale the graph in ratio 1:10.

I.e; 1 unit on the parabola is being represented by 10 unit on the scale

So, x (on the new parabola) = 1/10 of old x.

So, the new equation of the parabola = 1/10x²

New equation = 0.1x²

Hence, the equation of the new parabola is calculated as 0.1x²
