Which illustrates the construction of a perpendicular to a line from a point on the line?

quester [9]

I believe the correct answer from the choices listed above is the last option. The last option clearly describes the illustration of the construction of a perpendicular to a line from a point on the line where you start on a point in the line. Using an arbitrary radius, draw arcs intersecting the line <span> at two points. </span>
Hope this answers the question. Have a nice day.

Solve (2a^x + 1/2b^x)^2

alexira [117]

Answer:

$(4a^{2x} )+2a^{x} b^{x} + \frac{b^{2x} }{4}$

Step-by-step explanation:

The given equation is

$(2a^x + \frac{1}{2}b^{x} } )^2$ ...........(i)

we know the formula i.e.

$(a+b)^{2}= a^{2}+ b^{2} +2(a)(b)$

Applying this formula on equation (i) gives

= $(2a^{x} )^{2} +(\frac{1}{2})^{2}*(b^{x} )^{2} + 2 (2a^{x} )(\frac{1}{2} b^{x})$

Opening the sqaure gives and canceling $\frac{1}{2}$ with 2 gives us

= $4a^{2x} + \frac{1}{4}b^{2x} + 2a^{x}b^{x}$

= $(4a^{2x} )+2a^{x} b^{x} + \frac{b^{2x} }{4}$

which is the answer

Suppose that a recent poll of American households about car ownership found that for households with a car, 39% owned a sedan, 3

Dimas [21]

Let the total number of cars = 100

Total of sedan, van and sports cars = 39+33+7 = 79

Number of other cars = 100 - 79 = 21.

Let A be the event of owning a sedan,

B be the event of owning a van and

C be the event of owning a sports car.

D be the event of owning other cars.

Then, $p(A) = \frac{39}{100}$

$p(B)=\frac{33}{100}$ and

$p(C) = \frac{7}{100}$

$p(D) = \frac{21}{100}$

Now,

p(non selection of van) = p(A ∪ C ∪ D)

= p(A) + p(C) + p(D)

$=\frac{39}{100} +\frac{7}{100} +\frac{21}{100}$

$=\frac{67}{100}$

= 0.67

The probability of none of the three selections would be a van is:

0.67 × 0.67 × 0.67

= 0.300763

=0.301

Hence, the correct option is (D).

The larger of two numbers is three less than three times the smaller number. If the sum of the numbers is 61, what are the two n

Levart [38]

Answer:

Hi there!

Your answer is;

B) 16 and 45

Step-by-step explanation:

larger = 3s -3

smaller = s

Add together

3s -3 + s = 61

4s-3 = 61

+3

4s = 64

/4

s = 16

Plug into larger equation

3(16)-3= 45

Larger number = 45

Smaller number = 16

Hopefully this helps
