Is -2, -12, -60, -120 a geometric sequence?

Mathematics
1 answer:
nlexa [21]3 years ago
7 0

given,

1st term(a)= -2

2nd term (t2) =-12

3rd term (t3) =-60

4th term(t4)= -120

here common ratio (r)=t2/t1=t4/t3

or, -12/-2= -120/-60

or,6=2

hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.

X = 10

The triangles are similar by SAS, so we can set up a proportion of their sides.

9/(33-9) = 12/(3x+2)
9/24 = 12/3x+2

Reduce
3/8 = 12/3x+2

Cross multiply
3(3x+2) = 12*8

Distribute and multiply
9x + 6 = 96

Subtract 6
9x = 90

Divide by 9
x = 10

Check:
9/24 = 12/3x+2
9/24 = 12/3*10 + 2
9/24 = 12/30 + 2
9/24 = 12/32
3/8 = 3/8 :)

Write the equation of the line that is perpendicular to y=2x-7 and passes through the point (6, 5)
Pani-rosa [81]

Answer:

B

Step-by-step explanation:

we are given a equation of a line

we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points

in order to do so

recall that,

\displaystyle m_{ \text{perpendicular}} =   - \frac{1}{m}

we got from our given equation that m=2

because equation of a line is y=mx+b

thus

\displaystyle m_{ \text{perpendicular}} =   - \frac{1}{2}

remember that, when we want to figure out perpendicular line or parallel line we should the formula given by

\displaystyle y -  y_{1} = m(x -  x_{1})

since we got our perpendicular m is -½, x_1=6 and y_1=5, substitute

\displaystyle y -  5 =   - \frac{1}{2} (x -  6)

to get the perpendicular equation you should simplify the above equation to y=mx+b form

distribute -½:

\displaystyle y -  5 =   - \frac{1}{2} x  + 3

add 5 to both sides:

\displaystyle y  =   - \frac{1}{2} x  + 8

hence,

our answer choice is B

Write two expressions to show the total area of advertisement space on one page.
valina [46]

The area covered by the advertisement on the page is ab  \ unit^2.

<h3>What is the definition of area of a rectangle?</h3>

The area of a rectangle covers is the space it takes up inside the boundaries of its four sides. The dimensions of a rectangle determine its area. In general, the area of a rectangle is equal to the product of its length and breadth of the rectangle.

The formula of area of rectangle is length \times breadth unit^2

let the given page represents a rectangle.

We take the length of the advertisement is a unit and breadth of the advertisement is b unit.

The area of the advertisement =a \times b \ unit^2

                                                   =ab \ unit^2

Therefore, the area covered by the advertisement on the page is ab  \ unit^2
