Answer:
5.25 or 5 1/4
Step-by-step explanation:
The value of a and b in terms of equation are; a = 3 + b and b = a + 18.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
We are given polynomial, h(t) = 2t - at + bt + 4 represents Mr. Bill's height in metres at 't seconds. "-Mr." Bill is rapidly approaching a tall brick wall which is 100 metres high and will reach the wall in 3 seconds.
h = 100 metres
t = 3 seconds
Now substitute the values;
h(t) = 2t - at + bt + 4
100 = 2(3) - a(3) + b(3) + 4
100 = 6 - 3a + 3b + 4
3a + 90 = 3b
We need to find out if Mr. Bill will clear the wall or slam into it!
h(t) = 2t - at + bt+4 has a remainder of 9 when divided by (t-1) and a remainder of "-36" when divided by (t+2).
When t = 1
Then;
h(t) = 2t - at + bt + 4
9 = 2(1) - a(1) + b(1) + 4
9 = 6 - a + b
a = 3 + b
When time t = -2
Then; h(t) = 2t - at + bt + 4
-36= 2(-2) - a(-2) + b(-2) + 4
-36 = -4 + 2a - 2b + 4
-18 = a - b
b = a + 18

Answer:
a. -0.89
Step-by-step explanation:
The easiest way to solve this is that 0.03 - 0.92 is also the same thing as -0.92 + 0.03, your answer should be -0.89 which you are adding up 0.03.
