Answer:

CAB = 54

ABC = 21

ACB = 105

DCB = 75

Step-by-step explanation:

18x - 15 = (13x - 11) + (4x + 1)

18x - 15 = 17x - 10

x = 5

CAB = 13x - 11 = 13(5) - 11 = 65 - 11 = 54

ABC = 4x + 1 = 4(5) + 1 = 20 + 1 = 21

ACB = 180 - (CAB + ABC) = 180 - (54 + 21) = 180 - 75 = 105

DCB = 180 - ACB = 180 - 105 = 75

Which statement or statements apply to a bond which is selling at a premium?
SSSSS [86.1K]

Answer:

The best option is:

(a) I and II only

Step-by-step explanation:

Each kind of bond has a face value, usually known as par value. If a bond sells above the par value, it is a premium bond, if it sells below the par value, it is a discount bond. Hence first statement is true.

If a bond has a selling rate of 100, it means it is selling at its par value. For example if a bond has a par value of $100, then a selling rate of 100 means it sells at 100$, a selling rate of 90 means it sell at 90$, a selling rate of 120 means it sells at $120. For a premium bond, the selling rate is always above 100. Hence second statement is true.

Premium bonds are mostly sold by corporations, but alot of scheme of trading premium bonds have also been introduced by governments all around the world. We can say that the statement can be true for some specific country, but globally speaking, the statement is false.

(will mark brainliest ) Which of the following best describes the expression 5(x + 2)? (5 points)
Lunna [17]

Answer:

Step-by-step explanation:

The only one of these possible answers that could be correct is the fourth one:

The product of a constant factor 5 and a 2-term factor x + 2.  That '5' in front of (x+2) multiplies (x+2), and so the result is a product.

Rewrite the function by completing the square. f(x)= x^{2} -9 x +14f(x)=x 2 −9x+14
Bess [88]

Answer:

f(x)=(x-4.5)^{2}-6.25  or f(x)=(1/4)(2x-9)^{2}-6.25

Step-by-step explanation:

we have

f(x)=x^{2}-9x+14

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)-14=x^{2}-9x

Complete the square. Remember to balance the equation by adding the same constants to each side

f(x)-14+4.5^{2}=x^{2}-9x+4.5^{2}

f(x)+6.25=x^{2}-9x+4.5^{2}

Rewrite as perfect squares

f(x)+6.25=(x-4.5)^{2}

f(x)=(x-4.5)^{2}-6.25

f(x)=(1/4)(2x-9)^{2}-6.25

What is the product of 60?
Rzqust [24]
We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2.
