Can you guys help me with this please it suppose to use the synthetic substitution or the remainder theorem.
9514 1404 393
Answer:
(b) -36
Step-by-step explanation:
Synthetic division is often performed using a table of the kind shown in the attachment. The coefficients of f(x) are placed across the top, and the x-value to be evaluated is placed at the left. The rule for finding table entries is shown. (The first (left-most) number at the bottom is the leading coefficient of the polynomial.)
This table shows the remainder, which is f(-2), is -36.
__
The equation itself can be rewritten in "Horner form" to facilitate evaluation.
f(x) = (((-x +2)x -1)x +4)x +8
In this form, substituting for x and doing the evaluation is easier for mental arithmetic. You will notice that the contents of parentheses at each level match the bottom line of the synthetic division table.
f(-2) = (((-(-2) +2)(-2) -1)(-2) +4)(-2) +8
= (((4)(-2) -1)(-2) +4)(-2) +8
= ((-9)(-2) +4)(-2) +8
= (22)(-2) +8
= -36
f(-2) = -36 . . . . remainder from synthetic substitution

Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right
Solve for the nearest tenth
Solve for the missing side
Answer:
[tex]\Huge\boxed{x=11.8}[/tex]
Step-by-step explanation:
Hello There
cos = adjacent divided by hypotenuse
the adjacent side of the angle that has a measure of 49 is x and the hypotenuse is 18
so
[tex]cos49=\frac{x}{18}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 18 we multiply each side by 18
[tex]\frac{x}{18} *=x\\cos49*18=18cos49[/tex]
we're left with
[tex]x=18cos49[/tex]
now we let the calculator do the rest of the work
we end up with
[tex]x=11.80906252[/tex]
our final step would be to round to the nearest tenth
so we can conclude that the x = 11.8

Please label the missing angles below.
Answer:
Triangle A: 38 degrees
Triangle B: Unknown (not enough information)
Triangle C: Unknown (not enough information)
Triangle D: 70 degrees
Triangle E: 40 degrees
Step-by-step explanation:
Work for Triangle A: 90 + 52 = 142. 180 - 142 = 38.
Work for Triangle B: Unidentifiable because there is no indicator to tell you if any of the angles/lines are equal. Generally there will be a "double lined" indicator in the corners of which a triangles angles are equal.
Work for Triangle C: Same as B.
Work for Triangle D: 90 + 20 = 110. 180 - 110 = 70.
Work for Triangle E: 90 + 50 = 140. 180 - 140 = 40.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Question:
Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Answer:
[tex]y=x +45[/tex]
[tex]y = 45 + x[/tex]
Step-by-step explanation:
From the complete question, we have:
Jordyn & Teri
[tex]Rolls = 1[/tex]
[tex]Extra = 45\ yd[/tex]
Morgan
[tex]Rolls = 3[/tex]
[tex]Extra= 10\ yd[/tex]
Required
Expression for Jordyn and Morgan
Let the total kite by Jordyn and Teri be represented with y
This is calculated as:
[tex]y = Rolls + Extra\ Yard[/tex]
This gives:
[tex]y = 1\ roll + 45yd[/tex]
1 roll is represented with x.
So:
[tex]y=1x +45[/tex]
[tex]y=x +45[/tex]
This can be rewritten as:
[tex]y = 45 + x[/tex]

4 can divide both the numerator and denominator. So divide the numerator and denominator by 4
This gives 402 / 67
Th 67 multiplication table
67 x 1 = 67
67 x 2 = 134
67 x 3 = 201
67 x 4 = 268
67 x 5 = 335
67 x 6 = 402
the value of the expression would thus be 6

Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

You and your friend were working the ticket table at the last school basketball game.
The tickets sold for $5 for adults and $3 for students.
A total of 375 people attended the
game and a total of $1375 was taken in at the ticket table. How many adult tickets were
sold and how many student tickets were sold?
Answer:
Step-by-step explanation:
First
a+s=375
a=375-s
Next
5a+3s=1375, now using a found above makes this equation become
5(375-s)+3s=1375
1875-5s+3s=1375
1875-2s=1375
-2s=-500
s=250, since a=375-s
a=375-250
a=125
So 125 adult and 250 student tickets were sold.
