Answer:

1.2 x [tex]10^{14}[/tex]

Step-by-step explanation:

Scientific notation OR standard form:

This is expressed in powers of 10 (i.e [tex]10^{x}[/tex])

If the decimal point cannot be visibly seen, you can deduce that the decimal point is currently located after the last digit (i.e ‘0’).

For the number to be expressed in scientific notation, the decimal point has to be placed right after the first digit (which is NOT a zero) in the left most direction.

For this number, the decimal point has to be placed right after the ‘1’.  Therefore, the decimal point will be moving 14 places to the left. In addition, this 14 is considered as the positive power of 10.

Answer:

1.2 × 10¹⁴

Step-by-step explanation:

Scientific notation is written in the form [tex]a \times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one non-zero digit to the left of the decimal point.

The number of times you have moved the decimal point is the power of 10 (the value of n).

Therefore, to convert 120,000,000,000,000 to scientific notation, move the decimal point 14 places to the left so that [tex]a[/tex] is 1.2.

As the decimal point has been moved 14 places the left, we need to multiply 1.2 by 10¹⁴.

Therefore,  120,000,000,000,000 = 1.2 × 10¹⁴.

Answer:

By Thales' Rule (aka "the angle in a semicircle is a right angle"), since PR is a diameter,angle PQR is 90 degrees, i.e. PQ is perpendicular to QR, so their gradients multiply to -1.Thus 8/12 * -6/(a-9) = -1, so 12(a-9) = 48, so a-9 = 4, so a=13, as required.

Step-by-step explanation:

The discount can be found by subtracting the sale price from the original price:

$25.40 - $16.51 = $8.89

So the discount was $8.89.

To find the percent discount, we can divide the discount by the original price and multiply by 100:

$8.89 / $25.40 * 100% = 35%

Therefore, the percent discount from the coupon was 35%.

For the statement "Integer x divisible by 6" the option C is correct.

Either statements are NOT sufficient, but BOTH together are sufficient.

What is integer?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

(1) x + 3 is divisible by 3

This means that x is a multiple of 3.

Hence x + 3 is a multiple of 3.

But x could be 0, 3, 6. If x = 3, x is not divisible by 6.

Otherwise it is.

So, this statement is insufficient.

(2) x + 3 is an odd number

This means that x is an even number.

X can be 6, or 10.

So, this statement is insufficient.

Together -

From (1) it is known that x is a multiple of 3.

Hence X can be 0,3,6,9,12,15,18,21,24,27,30.

From (2) it is known that x is even.

Hence X can be 0,6,12,18,24,30.

Therefore, x is divisible by 6.

The values of x for which gh(x) = f(x) are -1 and -4.

As a result, we have gh(x) = g(h(x)) = g(x + 2). ² = x² + 4x + 4 f(x) = -x

The equation must be solved in order to determine the range of x values for which gh(x) = f(x):

x² + 4x + 4 = -x

When all the phrases are moved to the left, we obtain:

x² + 5x + 4 = 0

This quadratic equation has the following factors:

(x + 1)(x + 4) = 0

Thus, either x + 1 = 0 or x + 4 = 0 is the answer.

We obtain x = -1 or x = -4 after solving for x.

Hence, -1 and -4 are the values of x for which gh(x) = f(x).

Since both the coordinates of (-2,-3) are negative the point lies in option B: quadrant iii.

What is a quadrant?

A quadrant is an area or section of a cartesian plane that results from the intersection of two axes. It is used to establish a point's location in a plane.

Consider the point A = (x,y) given in the coordinate system, where x and y are arbitrary numbers.

If x and y are positive numbers then point A is in the first quadrant.

If x is negative number and y is positive then point A is in the second quadrant.

If x and y are negative numbers then point A is in the third quadrant.

If x  is positive number and y is negative then point A is in the fourth quadrant.

Now the given point is (-2,-3).

The first coordinate of this point is a negative number, and the second is also negative.

So, the point lies in third quadrant.

The solution set of the given homogeneous system in parametric vector form is x₁ = 5 = x₂ , x₃ = 1.

What is parametric vector form?

The identity matrix's two columns, which stand in for the two leading coefficients in the row echelon form of the original matrix, are added to create the parametric vector.

We are given set of equations as:

x₁ + 2x₂ - 15x₃ = 0

2x₁ + x₂ - 15x₃ = 0

-x₁ + x₂ = 0

Now, representing this in the matrix form, we get

[tex]\left[\begin{array}{cccc}1&2&-15&0\\2&1&-15&0\\-1&1&0&0\end{array}\right][/tex]

Now, we will reduce the matrix i.e. in row echelon form using elementary operations

From this, we get

[tex]\left[\begin{array}{cccc}1&0&-5&0\\0&1&-5&0\\0&0&0&0\end{array}\right][/tex]

So, we get that x₃ is the free variable.

Now, representing this in the parametric vector form, we get

x₁ - 5x₃ = 0

x₂ - 5x₃ = 0

x₃ = x₃

From this, we get

x₁ = 5x₃

x₂ = 5x₃

x₃ = x₃

So, we now get

x = [tex]\left[\begin{array}{c}x_{1} &x_{2} &x_{3} \end{array}\right][/tex]

This is equal to

x = [tex]\left[\begin{array}{c}5x_{3} &5x_{3} &x_{3} \end{array}\right][/tex]

Thus,

x = [tex]\left[\begin{array}{c}5 &5 &1 \end{array}\right][/tex]

Hence, the solution is x₁ = 5 = x₂ , x₃ = 1.

Answer:

The investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.

Step-by-step explanation:

The compound interest formula is:

A = P * (1 + (r/n))^(nt)

where

A is the amount of the investment after t years,

P is the principal amount (9070),

r is the annual interest rate (3.3%),

n is the number of times the interest is compounded per year (2),

t is the number of years (17).

Using the formula:

A = 9070 * (1 + (0.033/2))^(2 * 17)

A = 9070 * (1.0165)^34

A = 9070 * 1.882611

A = 16898.67 to the nearest cent.

So the investment will be worth $16898.67 after 17 years, compounded semiannually at 3.3% per year.

The line has a slope of - 3/4.

The line has a slope of 3/4.

Step-by-step explanation:

To determine the slope of a line passing through two points, you can use the formula:

Slope = (y2 - y1) / (x2 - x1)

Using the points (-6, 8) and (-3, 4), the slope would be:

Slope = (4 - 8) / (-3 - (-6)) = -4 / 3 = -4/3

So, the line has a slope of -4/3. The other statements in the list are not necessarily true based on the given information.

1) The perimeter of the composite figure is 31.9

2) The area of the composite figure is 64.25

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

There are 2 shapes: half circle and right triangle

diameter of half circle ,d=10

radius, r=d/2 = 10/2 = 5

Perimeter of half circle = π r = 3.14 * 5 = 15.7

In the right triangle,

base = 5, line perpendicular to  base = 10

hypotenuse² = squares of  other 2 sides  added

                       = 5² + 10²

                       = 25 +100

                       = 125

hypotenuse = ± √125 = ±11.18

consider positive for length

hypotenuse = 11.18

The perimeter of the composite figure

= Perimeter of half circle +base of  right triangle + hypotenuse of  right triangle

=15.7 + 5 +  11.18

= 31.9

Area of  half circle = 0.5*π *r² = 0.5*3.14*5² = 39.25

Area of  right triangle = 0.5*base * height

                                     = 0.5*5*10

                                     =  25

The area of the composite figure

=Area of  half circle + Area of  right triangle

The scale factor for the ratios of 1 in : 14 feet and 1 in : 30 yards without units are 1: 168 and 1: 1080 respectively.

Scale factor is the ratio between the scale of a given original object and a new object, which is its representation but of a different size either bigger or smaller.

For the ratio 1 in : 14 feet, we convert to the same unit in inches:

1 foot = 12 inches

14 feet = 12 × 14 inches

14 feet = 168 inches

1 in = 168 in

1 : 168

For the ratio 1 in : 30 yards, we convert to the same unit in inches:

1 yard = 36 inches

30 yards = 36 × 30 inches

30 yards = 1080 inches

1 in = 1080 in

1 : 1080

Therefore, the scale factor for the ratios of 1 in : 14 feet and 1 in : 30 yards without units are 1 : 168 and 1 : 1080 respectively.
