Jlenok [28]

F(-9) = -(-9)2 - 4(-9) - 19
= 18 + 36 - 19
= 35

On March 20, 2011, a $1,000 bond had a selling price of $987.50. What was the quoted price for the bond?

Leviafan [203]

Answer:

98.75%.

Step-by-step explanation:

On March 20, 2011, a $1000 bond had a selling price of $987.50.

We are asked what will be the quoted price for the bond.

Now, the quoted price of a bond is the price at which the bond was last traded and it is expressed as the percentage of the original bond value.

So, in our case the quoted price will be $\frac{987.50}{1000} \times 100 = 98.75$ %. (Answer)

Anyoneee help im stuck !! 15 points!!

Gnom [1K]

Answer:

Given: $\angle 1$ , $\angle 2$ , $\angle 3$ , $\angle 4$ formed by two intersecting segments.

In the given figure;

Linear pair states that a pair adjacent angle formed when two lines intersect.

Then by definition of linear pairs,

$\angle 1$ and $\angle 2$ forms a linear pair

Also, $\angle 2$ and $\angle 3$ forms a linear pair.

Linear pair postulates states that the two angle that forms a linear pair are supplementary(i,e add up to 180 degree).

Then by linear pair postulates;

$m\angle 1+ m\angle 2 =180^{\circ}$

and

$m\angle 2+m \angle 3 =180^{\circ}$

Substitution property of equality states that if x =y then, x can be substituted in for y or vice -versa.

then by substitution property of equality:

$m\angle 1+m\angle 2=m\angle 2+ m\angle 3$

Addition property of equality states that:

if x =y, then x + z = y+ z

By addition property of equality:

$m\angle 1 =m\angle 3$ hence proved!

David tracks his calories burned while training for a meet. The number of calories he burns is expressed by the function c(t) =

Scrat [10]

To find for the composite function of calories burned while swimming flippers using the two given functions, all we have to do is to plug in the function of c (t) to the function b (c). By doing this combination, we can create a function in the form of b [c (t)].

We are given the 2 functions:

c (t) = 704 t

b (c) = 1.3 c

To solve this, just simply combine the 2 but combine c (t) to b(c) since we are looking for the composite function of calories burned while swimming with flippers. Not b (c) to c (t).

b [c (t)] = 1.3 (704 t)

b [c (t)] = 915.2 t
