If x2 + 3x + 7 is divided by x + 2, then what is the remainder?
Answer:
ok but thx for the points
Step-by-step explanation:
The remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).
Given the polynomial; f(x) = x² + 3x + 7, since it is divided by x + 2, hence:
x + 2 = 0
x = -2
f(-2) = (-2)² + 3(-2) + 7 = 5
Hence the remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

In the given figure, PQ=PR and QS is the bisector of angle PQR. If angle PQS=30°, find angle PSQ.
Answer:
90°
Step-by-step explanation:
PQ=PR ⇒
∠PQR = ∠PRQQS is the bisector of angle PQR ⇒
∠PQS= ∠RQSIf angle PQS=30°, find angle PSQ
∠PQS=30° ⇒
∠PQR = 2*∠PQS = 2*30° = 60°As ∠PQR = 60°,
∠PRQ = 60° and ∠QPR = 60° as remaining angleSo,
∠PSQ = 180° - (∠QPR + ∠PQS) = 180° - 90° = 90°Find the perimeter of the figure below, in feet.

You deposit $6000 in an account earning 8% interest compounded monthly. How much will you have in the account in 15 years?
Answer:
13,200
Step-by-step explanation:
6000/100=60
60x8=480
480x15=7,200
6,000+7,200=13,200
If the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.
What is compound interest?Compound interest is the interest calculated on the principal and the aggregate interest. It may be copounded annually,semi annually, monthly, bimonthly,etc.
How to calculate interest?We have been given that the deposit is $6000,rate is 8% which is compounded monthly.
So effective rate of interest will be 8/1200=0.0067.
n will be 15*12=180
The sum after 15 years=6000[tex](1+0.0067)^{180}[/tex]
S=6000[tex](1+0.0067)^{180}[/tex]
Take log both sides.
log S=log 6000[tex](1+0.0067)^{180}[/tex]
log S=log 6000+log [tex](1+0.0067)^{180}[/tex]
log S=log 6000+180 log (1.0067)
log S=3.7781+180*0.0029
log S=3.7781+0.522
log S=4.3001
S=AL (4.3001)
S=19957.218
Hence if the initial amount is $6000 , rate of interest 8% then after 15 years the amount willbe $19957.218.

slope 5/6, passes through (12,4)
Answer:
y= 5/6x -6
Step-by-step explanation:
[tex]m =\frac{5}{6} \\(12,4)=(x_1,y_1)\\\\[/tex]
Substitute values into point slope form
[tex]y-y_1 =m(x-x_1)\\\\y - 4 = \frac{5}{6} (x-12)\\\\y-4 = \frac{5}{6} x -10\\\\y=\frac{5}{6} x -10+4\\\\y = \frac{5}{6} x -6[/tex]
The equation of the line that has a slope of 5/6 and passes through (12, 4) will be y = 5/6) x - 6.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is 5/6. Then the equation of the line will be
y = (5/6)x + c
The equation of the line is passing through (12, 4), then the value of c will be
4 = (5/6) 12 + c
4 = 10 + c
c = -6
Then the equation of the line will be y = (5/6)x - 6.

if de = 6x , EF =4x, and df =10 what is DE
Answer: 6
Step-by-step explanation:
Given DE, EF and DF, we know that DE and EF make up DF. We add DE and EF and set it equal to DF.
6x+4x=10 [add]
10x=10 [divide both sides by 10]
x=1
Now that we know x=1, we can plug that into DE.
6(1)=6
Now, we know that DE is 6.
