9. The gradient of the curve y=kx⁴ at the point x = 2 is 128. Find the value of k.
Answer:
k = 4
Step-by-step explanation:
Here, we want to find the value of k
Mathematically, the gradient of a curve is same as the first derivative
so the first derivative here is;
dy/dx = 4kx^3
Now, the value of x here is 2 while the value of y is 128
Substituting these values;
128 = 4k(2)^3
128 = 32k
k = 128/32
k = 4
A pizza parlor sells pizza in two sizes, a 16 inch pizza or a 10inch pizza. Which is more pizza, half of the 16-inch pizza or the entire inch pizza?
Topic: arc length and sector area
Answer:
Therefore the second pizza of 10inch is More
Y>X
Step-by-step explanation:
From the question we are told that:
Diameter of pizzas
Pizza one [tex]D_1=16[/tex]
Pizza two [tex]D_2=10[/tex]
Generally the equation for amount of half of pizza one X is mathematically given by
[tex]X=\frac{1}{2}\pi r^2[/tex]
[tex]X=\frac{1}{2}\pi 8^2[/tex]
[tex]X=100.53inch^2[/tex]
Generally the equation for amount of pizza two Y is mathematically given by
[tex]Y=\pi r^2[/tex]
[tex]Y=\pi 10^2[/tex]
[tex]Y=314.16inch^2[/tex]
Therefore the second pizza of 10inch is More
Y>X

Subtracting fractions with unlike denominators
Answer:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
LCD(9/4, 5/10) = 20
[tex](\frac{9}{4} * \frac{5}{5} ) - (\frac{5}{10} * \frac{2}{2} ) = ?[/tex]
Complete the multiplication and the equation becomes
[tex]\frac{45}{20} - \frac{10}{20}[/tex]
The two fractions now have like denominators so you can subtract the numerators.
Then:
[tex]\frac{45 - 10}{20} = \frac{35}{20}[/tex]
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 20 using
GCF(35,20) = 5
[tex]\frac{35 / 5 }{20 / 5} = \frac{7}{4}[/tex]
The fraction
[tex]\frac{7}{4}[/tex]
is the same as
7 ÷ 4
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Apply the fractions formula for subtraction, to
[tex]\frac{9}{4} - \frac{5}{10}[/tex]
and solve
[tex]\frac{(9 * 10)- (5* 4) }{4 * 10}[/tex]
[tex]= \frac{90-20}{40}[/tex]
[tex]= \frac{70}{40}[/tex]
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,40) = 10
[tex]\frac{70/ 10 }{40 / 10} = \frac{7}{4}[/tex]
Convert to a mixed number using
long division for 7 ÷ 4 = 1R3, so
[tex]\frac{7}{4} = 1\frac{3}{4}[/tex]
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
In PQR the measure of R=90, QR=61 feet and RP=90 find the measure of P to the nearest degree.

What is the selling price per widget as a function of the
number of widgets produced, and what should the
selling price be if 15 widgets are produced?
Answer:
1240 widgets
Step-by-step explanation:
The value of the function at 870, the local maximum, is
= -0.02(870)2 + 34.80(870) - 4700
= -0.02(756900) + 30276 - 4700
= -15138 + 25576
= 10438
So the vertex is (870, 10438)
The cost t the company to produce 870 widgets is
C(870) = 4700 + 5.20(870) = 4700 + 4524 = 9224
So, the cost of the widgets plus the profit must be equal to the total sales, which is divided by the number of widgets reveal their individual price.
(10438 + 9224)/870 = 19662/870 = $22.60
P(x) = 7700
- 0.02x2 + 34.80x - 4700 = 7700
-0.02x2 + 34.80x -12400 = 0
x = {-34.80 ± √[(34.80)2 - 4(-0.02)(-12400)]}/2(-0.02)
x = [-34.80 ± √(1211.04 - 992)]/(-0.04)
x = (-34.80 ± √219.04)/(-0.04)
x = (-34.80 ± 14.8)/(-0.04)
x = 870 ± 370
so, $7700 in profits will be earned at either 500 widgets or 1240 widgets
Is anyone able to help me out with this???
Answer:
x = 24
Step-by-step explanation:
To simplify the work we can use the Pytaghoran theorem in this way:
x^2 + x^2 = (24√2)^2
2x^2 = 24^2 *(√2)^2
2x^2 = 576 * 2
x^2 = 576
x = +/- √576
x = +/- 24
we choose only the positive value because a length can’t be negative
x = 24
A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probability that the point is inside the circle?
Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,
[tex]A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2[/tex]
Area of square,
[tex]A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2[/tex]
Now, probability is given by :
[tex]P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785[/tex]
Therefore, the probability that the point is inside the circle is 0.785 .

Find the 53rd term of the arithmetic sequence -12, -1, 10
440 is the answer
Tn=a+(n-1)d
Tn=53
a= -12
n=53
d= 11
-12+(53-1)11 = 440
Answer:
560Step-by-step explanation:
The sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
Since we're finding the 53rd term
a = - 12
n = 53
d = -1 - ( -12) = - 1 + 12 = 11 or 10--1 = 10 +1 =11
d = 11
So we have
A(53) = - 12 + (11)(53 - 1)
= - 12 + 11(52)
= -12 + 572
= 560
We have the final answer as
560Hope this helps you

Hello, can you help me please
Step-by-step explanation:
1. C(x) is in vertex form so let write the function out.
[tex]a(x - 1) {}^{2} + b[/tex]
B is our maximum value so b=9.
[tex]a(x - 1) { }^{2} + 9[/tex]
To find a, we know that when x=5 is a root so plug 5 in for x to find a.
[tex]a(5 - 1) {}^{2} + 9 = 0[/tex]
[tex]a(4) {}^{2} + 9 = 0[/tex]
[tex]16a = - 9[/tex]
[tex]a = - \frac{9}{16} [/tex]
2.. Let convert Chelesa function into. standard form.
[tex] \frac{ -9 }{16} (x - 1) {}^{2} + 9[/tex]
[tex] - \frac{9}{16} (x {}^{2} - 2x + 1) + 9[/tex]
[tex] - \frac{9}{16} {x}^{2} + \frac{9}{8} x + \frac{135}{16} [/tex]
Let see which value has the higher constant.
135/16 is more than 8 so Chelsea jumper higher.
3. Set Herritea equation equal to zero.
[tex] - \frac{2}{9} {x }^{2} + 8 = 0[/tex]
[tex] - \frac{2}{9} x {}^{2} = - 8[/tex]
Multiply both sides by the reciprocal of negative 2/9.
[tex] {x}^{2} = - 8 \times - \frac{9}{2} [/tex]
[tex] {x}^{2} = 36[/tex]
[tex]x = 6[/tex]

A farmer sells 8.1 kilograms of apples and pears at the farmer's market. 2 5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
The question is incomplete:
A farmer sells 8.1 kilograms of apples and pears at the farmer's market. 2/5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answer:
She sold 4.86 kg of pears at the farmer's market.
Step-by-step explanation:
With information provided, you know the amount of kilograms of apples and pears sold and that 2/5 of this weight is apples, so you can find first the number of kilograms of apples sold by multipying 2/5 for 8.1 kilograms:
2/5*8.1=3.24 kg
Now, you can find the kilograms of pears that the farmer sold by subtracting the kilograms of apples sold from the total amount of apples and pears sold:
8.1-3.24=4.86 kg
According to this, the answer is that she sold 4.86 kg of pears at the farmer's market.

Find the measure of the indicated arc
Answer:
m(arc WXY) = 224°
Step-by-step explanation:
By inscribed angle theorem,,
"Measure of intercepted arc is double of the inscribed angle"
m(arc WXY) = 2[m(∠YCW)]
Here, arc WXY is the intercepted arc and ∠YCW is the inscribed angle.
By substituting the value of inscribed angle,
m(arc WXY) = 2(112°)
= 224°
Therefore, measure of arc WXY is 224°.
