The quotient of dividing (3x⁴ - 2x³ + 7x² - 4) by (x - 3) is 3x³ + 7x² + 28x + 84 and the remainder is 248
How to determine the quotient and the remainder?The division expression is given as:
(3x⁴ - 2x³ + 7x² - 4) / (x - 3)
Set the divisor to 0
x - 3 = 0
Solve for x
x = 3
Substitute x = 3 in 3x⁴ - 2x³ + 7x² - 4
3x⁴ - 2x³ + 7x² - 4 = 3(3)⁴ - 2(3)³ + 7(3)² - 4
Evaluate
3x⁴ - 2x³ + 7x² - 4 = 248
This means that the remainder is 248
Recall that:
Dividend = Divisor * Quotient + Remainder
So, we have:
3x⁴ - 2x³ + 7x² - 4 = x - 3 * Q + 248
Subtract 248 from both sides
3x⁴ - 2x³ + 7x² - 252 = x - 3 * Q
Divide both sides by x - 3
Q = (3x⁴ - 2x³ + 7x² - 252)/(x - 3)
Factorize the numerator
Q = (x - 3)(3x³ + 7x² + 28x + 84)/(x - 3)
Cancel out the common factors
Q = 3x³ + 7x² + 28x + 84
Hence, the quotient is 3x³ + 7x² + 28x + 84 and the remainder is 248

747.7 plus a 15% increase
Answers
Answer:
[tex]859.855[/tex]
Step-by-step explanation:
You start with the current amount:
[tex]747.7[/tex]
First calculate [tex]15\%[/tex] of [tex]747.7[/tex]:
[tex]747.7 \cdot 0.15 = 112.155[/tex]
Now add that new value back into the original amount:
[tex]747.7 + 112.155 = 859.855[/tex]
As a trick to speed things up, you can calculate it in one expression:
[tex]747.7 \cdot 1.15 = 859.855[/tex]
Use the formula pH = log (1/H*) to find the pH of the substance given its concentration
of hydrogen ions in a liter of acid rain that has a pH. Round your answer to the nearest
ten-thousandth.
10. pH = 3.6
Answers
log(1/H*) = log(1) - log(H*)
No matter what base we’re using, log(1) = 0, so this simplifies to -log(H*). We’re also given a pH value of 3.6, so we can substitute this value into the original equation along with -log(H*) to get
3.6 = -log(H*)
Multiplying by -1 on both sides:
-3.6 = log(H*)
And rewriting in exponential form:
H* = 10^(-3.6) = 0.0003 (rounded to the nearest ten thousandth)

Answer:

Step-by-step explanation:
Given:
equation of the parabola: [tex]y=a(x-1)^2+q[/tex]points on the parabola: (-1, -9) and (1, 1)Substitute point (1, 1) into the given equation of the parabola to find q:
[tex]\begin{aligned}\textsf{At}\:(1,1)\implies a(1-1)^2+q &=1\\a(0)^2+q &=1\\q &=1\end{aligned}[/tex]
Substitute the found value of q and point (-1, -9) into the given equation of the parabola to find a:
[tex]\begin{aligned}\textsf{At}\:(-1,-9)\implies a(-1-1)^2+1 &=-9\\a(-2)^2+1 &=-9\\4a+1 &=-9\\4a &=-10\\a &=-\dfrac{5}{2}\end{aligned}[/tex]
Therefore, the equation of the parabola is:
[tex]y=-\dfrac{5}{2}(x-1)^2+1[/tex]
The maximum or minimum point on a parabola is the vertex.
Vertex form of a parabola: [tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex.
Therefore, the vertex of the parabola is (1, 1) and so the maximum value of y = 1
Vertex at (1,q)
There is a point already given from which parabola passes through its (1,1)
So q=1Hence
vertex=(1,1)Equation:-
y=a(x-h)²+ky=a(x-1)²+1Now put (-1,-9)
-9=a(-2)²+1-9=4a+14a=-10a=-5/2a is negative hence parabola is opening downwards
So
vertex is maximum

y=124. Which point is NOT on the circle with center (-4,3) and radius 6? a. (2,3) b. (2,0) c. (-4,-3) d. (-10,3)
Answers
Answer:
Your answer is b. (2,0) is not a point on the circle.
Step-by-step explanation:
Center of the Circle: (h,k) = (-4,3)
Radius of the Circle: r = 6
Find the points on the circle.
(h + r ,k)
(-4 + 6 , 3) = (2,3)(h - r ,k)
(-4 - 6 , 3) = (-10,3)(h , k + r)
(-4 , 3 + 6) = (-4,9)(h , k - r)
(-4 , 3 - 6) = (-4,-3)AXYZ is rotated 180°.

Answer:
w = 23
Step-by-step explanation:
so the total degree of a triangle is 180,
when you add all 3 it should equal 180.
35 + (5w) + (w + 7) = 180
subtract 35 from both sides, 35 - 35 + (5w) + (w + 7) = 180 - 35
(5w) + (w + 7) = 145
combine like terms (add the w's), (5w + w) + 7 = 145
6w + 7 = 145
subtract 7 from both sides, 6w + 7 - 7 = 145 - 7
6w = 138
divided both sides by 6 to get w alone, 6w / 6 = 138 / 6
w = 23

The exponential function which represent the graph shown in image is f(x)=2.(1/4)ˣ. Option C is correct.
What is an exponential function?Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
The exponential function with dependent variable y and independent variable x can be written as,
f(x)=a.bˣ
Here, x is the variable in the power of a number, b is a constant which is known as the change factor and a is the initial value of the function.
Here, in the graph, it passes from the (0,2) and (2,0) from x and y axis. it tells us that the initial value of is 2.
a=2
The graph is plotted on right side in opposite way, which tells the value of b is in the reciprocal. Thus,
b=1/4.
Put the values as,
f(x)=a.bˣ
f(x)=2.(1/4)ˣ
Hence, the exponential function which represent the graph shown in image is f(x)=2.(1/4)ˣ. Option C is correct.

What is an equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
We need to select correct statements from the given options.
2 ( x - 6 ) = - 35
