Which equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13

to make cocoa powder, cocoa beans are roasted. The ideal temperature for roasting is 300 fahrenheit, plus or minus 25 fahrenheit. Write and solve an equation describing the maximum and minimum roasting temperature for cocoa beans
The maximum and minimum roasting temperatures for cocoa beans will be 325°F and 275°F.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
To make cocoa powder, cocoa beans are roasted. The ideal temperature for roasting is 300 Fahrenheit, plus or minus 25 Fahrenheit. Then the expression is given mathematically as,
⇒ 300°F ± 35°F
For the maximum temperature, take a positive sign. Then we have
⇒ 300°F + 35°F
⇒ 325°F
For the minimum temperature, take a negative sign. Then we have
⇒ 300°F - 35°F
⇒ 275°F
The maximum and minimum roasting temperatures for cocoa beans will be 325°F and 275°F.

Evaluate the intergal F•dr where F (x,y,z)=xyi+yzj+zxk and c is the twisted cubic given by x=t, y=t^2 ,z=t^3, 0<=t=<1
The integral can be evaluated by substituting everything you know:
\(\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\int_C\mathbf F(x(t),y(t),z(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt\)
\(=\displaystyle\int_0^1(t^3\,\mathbf i+t^5\,\mathbf j+t^4\,\mathbf k)\cdot(\mathbf i+2t\,\mathbf j+3t^2\,\mathbf k)\,\mathrm dt\)
\(=\displaystyle\int_0^1(t^3+5t^6)\,\mathrm dt\)
\(=\dfrac{t^4}4+\dfrac{5t^7}7\bigg|_0^1=\dfrac14+\dfrac57=\boxed{\dfrac{27}{28}}\)
The line integral ∫F · dr along the curve is 9/10.
To evaluate the line integral ∫F · dr along the curve C, where F(x, y, z) = xyi + yzj + zxk and C is the twisted cubic given by x = t, y = t², z = t³ for 0 ≤ t ≤ 1, we need to parameterize the curve C and compute the dot product between F and the tangent vector dr.
The parameterization of C is:
r(t) = ti + t²j + t³k
To compute dr, we take the derivative of r(t) with respect to t:
dr = (dx/dt)i + (dy/dt)j + (dz/dt)k
dr = i + 2tj + 3t²k
Now we can compute the dot product between F and dr:
F · dr = (xy)(dx/dt) + (yz)(dy/dt) + (zx)(dz/dt)
F · dr = (t)(i) + (t²)(2t)(j) + (t)(t³)(3t²)(k)
F · dr = ti + 2t³j + 3t⁴k
To evaluate the line integral, we integrate F · dr with respect to t over the interval [0, 1]:
∫[0,1] F · dr = ∫[0,1] (ti + 2t³j + 3t⁴k) dt
Integrating each component separately:
∫[0,1] ti dt = (1/2)t² ∣[0,1] = (1/2)(1)² - (1/2)(0)² = 1/2
∫[0,1] 2t³j dt = (1/4)t⁴ ∣[0,1] = (1/4)(1)⁴ - (1/4)(0)⁴ = 1/4
∫[0,1] 3t⁴k dt = (1/5)t⁵ ∣[0,1] = (1/5)(1)⁵ - (1/5)(0)⁵ = 1/5
Adding the results together:
∫[0,1] F · dr = (1/2) + (1/4) + (1/5) = 5/10 + 2/10 + 2/10 = 9/10

The volume of a spherical balloon is increasing at a constant rate of 3 in3/s. At what rate is the radius of the balloon increasing at the instant its radius is 2 inches?
Answer:
0.0597in/s
Step-by-step explanation:
The volume of the spherical balloon V= 4/3πr³
r is the radius of the balloon
The rate at which the volume is changing dV/dt is expressed as;\
dV/dt = dV/dr*dr/dt
dV/dr = 3(4/3πr²)
dV/dr = 4πr²
dV/dr = 4π(2)²
dV/dr = 16π
dV/dt = 3 in³/s
Substitute inti the formula
3 = 16πdr/dt
dr/dt = 3/16π
dr/dt = 3/50.24
dr/dt = 0.0597in/s
Hence the balloon is increasing at the rate of 0.0597in/s

what is the equation of a line that passes through the points (2,5) and (4,3)
The equation of a line that passes through points (2,5) and (4,3) is
y = -x+7.
Finding the equation of a line:
First, we need to find out the slope for the given points.
(X1,Y1) = (2,5)
(X2,Y2) = (4,3)
formula for slope(m) = \(\frac{Y2 - Y1}{X2 - X1}\)
substitute the points in the above formula
\(\frac{3 - 5}{4 - 2}\) = \(\frac{-2}{2}\)
\(\frac{-2}{2}\) = -1
slope for the given points(m) = -1.
m = -1
The equation of a line is y-y1 = m(x-x1), where x and y are variables.
substituting the values in the above equation then :
y-5 = -1(x-2)
y-5 = -x+2
y+x = 2+5
x+y = 7
y = -x+7
Therefore, the equation of the line passing through the points (2,5) and (4,3) is y = -x+7

enter it like this: (42/53, 64/75)
If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."
The solution to the system of equations is (x, y) = (-261/47, 44/47) as an ordered pair.
To solve the given system of equations:
Equation 1: 8x + 9y = -36
Equation 2: x + 7y = 1
We can use the method of substitution or elimination to find the values of x and y. Let's use the method of substitution:
From Equation 2, we can solve for x:
x = 1 - 7y
Substituting this value of x into Equation 1:
8(1 - 7y) + 9y = -36
8 - 56y + 9y = -36
-47y = -44
y = 44/47
Substituting the value of y back into Equation 2 to find x:
x + 7(44/47) = 1
x + 308/47 = 1
x = 1 - 308/47
x = (47 - 308)/47
x = -261/47
Therefore, as an ordered pair, the solution to the system of equations is (x, y) = (-261/47, 44/47).

QUESTION 4 Sofia took a short term loan on 31st March 2022 from a bank that charged 6.5% simple interest rate. He was paid RM5555 to settle the loan after 11 months. a) Calculate the amount of the loan. b) Calculate the amount of interest charged. (3 marks) (2 marks)
Answer:
Step-by-step explanation:
a) To calculate the amount of the loan, we need to use the formula for simple interest:
I = Prt
Where I is the interest, P is the principal (the amount of the loan), r is the interest rate, and t is the time in years.
Since the loan was for 11 months, or 11/12 of a year, we can calculate the principal as:
P = I / (rt) = 5555 / (0.065 x 11/12) = RM75,000
Therefore, the amount of the loan was RM75,000.
b) To calculate the amount of interest charged, we can use the same formula and plug in the values we know:
I = Prt = 75,000 x 0.065 x 11/12 = RM4,354.17
Therefore, the amount of interest charged was RM4,354.17.
If annual interest rate is 8.25% on 90,900.00 What is my interest for 1/2 a month. It's for 8 years.
To calculate the interest for 1/2 a month over a period of 8 years, we first need to calculate the total number of months in 8 years:
Total number of months = 8 years x 12 months/year = 96 months
Next, we can calculate the interest for half a month:
Interest = Principal x Rate x Time
Where:
- Principal = $90,900.00
- Rate = 8.25% (annual interest rate)
- Time = 0.5/12 years (half a month, expressed in years)
Rate needs to be converted to a monthly rate, so we divide it by 12:
Rate = 8.25% / 12 = 0.6875% (monthly interest rate)
Time needs to be expressed in years, so we divide it by 12:
Time = 0.5/12 years
Now we can calculate the interest:
Interest = $90,900.00 x 0.006875 x 0.0416667
Interest = $25.08 (rounded to the nearest cent)
Therefore, the interest for 1/2 a month on a principal of $90,900.00 with an annual interest rate of 8.25% over a period of 8 years is $25.08.
Answer:
The interest for 1/2 month is $312.47, and the total interest for 8 years is $30, 032.64
Step-by-step explanation:
Make a plan:
Monthly Interest Rate: 8.25% / 12 = 0.006875Interest for 1/2 month is 90900 * 0.006875 * 0.5 = 312.46875Total Interest for 8 years is 312.46875 * 8 * 12 = 30032.64Solve the problem:The monthly Interest Rate is 8.25% / 12 = 0.006875 (Ground Truth)Interest for 1/2 month is 90900 * 0.006875 * 0.5 = 312.46875 (ground truth).Total Interest for 8 years is 312.46875 * 8 * 12 = 30032.64 (ground truth).Draw the conclusion:
The interest for 1/2 month is $312.47, and the total interest for 8 years is $30, 032.64Hope this helps!

Ratios
The proportion or ratios between variables measure the relative quantities of them by doing a division, usually expressed as fractions or a colon-separated pair of numbers.
To make fruit punch, Amar mixes 1 scoop of fruity powder with 5 cups of water. The ratio of fruity powder to water is 1:5.
We must select which recipe from the list won't produce the same ration and therefore will not taste the same as Amar's:
2 scoops of fruity powder:6 cups of water gives a ratio of 2:6. Simplifying by 2, the ratio is 1:3. This recipe will not test the same as Amar's.
2 scoops of fruity powder:10 cups of water gives a ratio of 2:10. Simplifying by 5, the ratio is 1:5. This recipe will test the same as Amar's.
0.5 scoop of fruity powder:2.5 cups of water gives a ratio of 0.5:2.5. Multiplying by 2, the ratio is 1:5. This recipe will test the same as Amar's.
5 scoops of fruity powder:25 cups of water gives a ratio of 5:25. Dividing by 5, the ratio is 1:5. This recipe will test the same as Amar's.
