Step-by-step explanation:
Given polynomial is,
x - 1 + 2x³ - 3x⁴ + 5x⁵
2.1) Number of terms in the given polynomial = 5
2.2) Degree of polynomial = Highest exponent of polynomial = 5
2.3) Constant term of the given polynomial = 1
2.4) Polynomial in descending order,
5x⁵ - 3x⁴ + 2x³ + x - 1
2.5) Value of polynomial at x = -1
5(-1)⁵ - 3(-1)⁴ + 2(-1)³ + (-1) - 1 = -5 - 3 - 2 - 1 - 1
= -12

Levi invests money in an account paying a simple interest of 8.7% per year. If he invests $70 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answer:
Pn=Po(1+r)^n
r=8.7%=8.7/100=0.087
Po=$70
n=1
P1=70(1+0.087)^1
=70(1.087)=76.09
=76
Answer:$76.09
Step-by-step explanation:
100%+8.7%=
108.7%\,\,108.7\%108.7%
Whole balance before interest = 100%, then add on interest
108.7% of the current balance means 108.7100 of it.\text{108.7\% of the current balance means \(\frac{108.7}{100}\) of it.}108.7% of the current balance means 100108.7 of it.
"Percent" literally means "out of 100."
108.7100=\frac{108.7}{100}=100108.7=
1.087\,\,1.0871.087
To find 108.7% of the current balance, multiply by 1.087:\text{To find 108.7\% of the current balance, multiply by \(1.087\):}To find 108.7% of the current balance, multiply by 1.087:
$70×1.087=\$70\times1.087=$70×1.087=
$76.09\,\,\boxed{\$76.09}$76.09

Maria invests £4500 in a savings account for 3 years the account pays simple interest at a rate of 1.8% per year work out the annual rate of simple interest
Answer:
£81Step-by-step explanation:
Given the following
Principal = £4500
Rate = 1.8%
Time = 3 years
Required
Annual simple interest
GEt the interest for the whole period first
SI = PRT/1pp
SI = 4500*1.8*3/100
SI = 45 * 1.8 * 3
SI = 243
Annual simple interest = Simple interest/Total number of years
Annual simple interest = 243/3
Annual simple interest = 81
Hence the annual simple interest is £81

what is 5-2(3-x)=4x+10
Answer:
Distribute -2 through the parentheses then calculat the difference then move the variable to the left-hand side and change its sign then move teh conatant to the right- hand side and change its sign then collect like terms then add the numbers then divide both sides of the equation by -2 and your answer is x=-11/2 or x=-5 1/2 or x=-5.5
Step-by-step explanation:
Answer:
Step 1: Simplify both sides of the equation.
5−2(3−x)=4x+10
5+(−2)(3)+(−2)(−x)=4x+10(Distribute)
5+−6+2x=4x+10
(2x)+(5+−6)=4x+10(Combine Like Terms)
2x+−1=4x+10
2x−1=4x+10
Step 2: Subtract 4x from both sides.
2x−1−4x=4x+10−4x
−2x−1=10
Step 3: Add 1 to both sides.
−2x−1+1=10+1
−2x=11
Step 4: Divide both sides by -2.
−2x
−2

Work out the value of
Answer:
x=12
Step-by-step explanation:
180 - 6x - 6x - 3x
180 - 15x
180 = 15x
180 / 15 = x
x = 12
6x + 6x + 3x = 180
180= 6x + 6x + 3x
180= 15x
x= 180/15
x= 12
