Alberto invests $1,130 in a savings
account with a fixed annual interest rate
compounded 6 times per year. After 8
years, the balance reaches $1,325.71.
What is the interest rate of the account?
The interest rate of the account is 2%
Compound interestFrom the question, we are to determine the interest rate of the account
From the compound interest formula, we have that
A = P(1 + r/n)^{nt}
Where A is the amount
P is the principal
r is the rate
n is the number of times compounded
t is the time in years
From the given information,
A = $1,325.71
P = $1,130
n = 6
t = 8 years
Thus,
1325.71 = 1130(1 + r/6)⁶⁽⁸⁾
1325.71 = 1130( 1 + r/6)⁴⁸
1325.71/1130 = ( 1 + r/6)⁴⁸
Take the 48th root of both sides
1.003333 = 1 + r/6
1.003333 - 1 = r/6
0.003333 = r/6
r = 6 × 0.003333
r = 0.019998
r ≈ 0.02
r ≈ 2%
Hence, the interest rate of the account is 2%.

In triangle PQR,work out the values of a ,b and c.Give your reason for you answer .
Answer:
m∠a = 100°
m∠b = 100°
m∠c = 110°
Step-by-step explanation:
Calculation of m∠a
∠a is an exterior angle of ΔPST .
Therefore m∠a = sum of the interior angles of ΔPST
m∠a = 30 + 70 = 100°
Calculation of m∠c
∠c and ∠PST are supplementary so their measures must add up to 180°
m∠c + 70° = 180° so m∠c = 180 - 70 = 110°
Calculation of m∠b
QRST is a quadrilateral.
The sum of the interior angles of the quadrilateral = 360°
So m∠a + m∠b + 50 + m∠c = 360°
We have already computed ∠a = 100° and ∠c = 110°
So 100 + m∠b + 50 + 110 = 360°
260 + m∠b = 360
m∠b = 360 - 260 = 100°

how many critical numbers does f(x) have? note: critical numbers must be within the domain of the function.
The critical number of the given function {g(t) = 3t ㏑t} is t = e⁻¹
What is critical number?Assume f(x) is a function with an open interval (a,b). If c is in the interval (a,b) and either f'(c) =0 or f'(c) does not exist, we say c is a critical number of f(x).
Each local minimum as well as maximum of f(x) must correspond to a critical number of f(x). The opposite is not truly the case: not all critical number of f(x) must correspond to a local maximum as well as minimum of f(x).
Now, as per the question;
It should be noted that the broadest possible domain of {g(t) = 3t ㏑t} is given in the set {t : t > 0} as ㏑t can not be defined for negative numbers of zero.
Now, differentiate the given function with respect to t.
[tex]g^{\prime}(t)=\frac{d}{d t}(3 t \ln t)[/tex]
Apply the product rule of differentiation;
[tex]\begin{aligned}&=\left[\frac{d}{d t}(3 t)\right] \ln t+3 t \frac{d}{d t}(\ln t) \\&=3 \ln t+3 t \frac{1}{t} \\&=3 \ln t+3 \\&=3(\ln t+1)\end{aligned}[/tex]
Now, put this value of g'(t) = 0 for finding the critical points.
0 = g'(t)
= 3(㏑t + 1)
Divide equation by 3.
0 = ㏑t + 1
㏑t = -1
Taking anti log;
t = e⁻¹ (critical value)

Since Barry is going to post-secondary school for three years, a personal line of credit is vital to pay for his education.
How to illustrate the information?It should be noted that when a individual collects a loan, the person will have to pay it back with an extra amount as interest.
In this case, it's important for him to use his personal line or credit rather than collecting a student loan from people. This isn't good in this scenario.

zero for the range of the exponential parent
function?
the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.
Why do we use parenthesis next to zero for the range of the exponential parent function?When we write in interval notation, the parenthesis are used to denote that the "ends" of the interval don't belong to the interval.
This means that in (a, b).
a and b don't belong to that interval.
While if instead we wrote [a, b]
In that case, a and b belong.
For the case of the exponential function:
y = a^x
As x tends to really large negative values, the value of y will tend to zero asymptotically. This means that y is really close to zero, but it is never equal to zero.
Then the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.

A dot plot is a type of graphical display that uses filled circles (dots) and a simple scale to compare counts (frequencies) within a category or group when working with small data sets with few groups . A chart with letters or words (non-numeric categories) on the x-axis is called a qualitative dot plot. The dot plot above is a qualitative dot plot because A, E, I, O, and U are not numeric. Qualitative variables cannot be described in terms of center, spread, or shape. If the x-axis contains numbers (numerical categories), it is called a quantitative dot plot. This dot plot can be described in terms of center, spread, or shape.Dot plots are used to represent small amounts of data. To analyze this chart, let's say four people are having a snack together. Snack selections are pizza, burgers, fries, and pasta. Using the dot plant, we can see that everyone chose pizza. Also, her 3 other people in your group added burgers to their snack plates.

this problem is solved by a system of equations
Let Arthur’s current age be represented by:a
His brother’s current age will be represented by: b
The first equation will be:
a = 7 + b
The second equation will be:
a + 8 = 2b
now we solve for the equations. Plug in a = 7+b into a in the second equation.
So now we have
b+7+8=2b
Simplify:
B+15=2b
15=b

The diameter of a strand of rope is 1.2 × inch. The diameter of a strand of floss is 2.0 × inch.
How much longer is the diameter of the strand of rope than the diameter of the strand of floss?
A. 2.0 × inch
B. 1.0 × inch
C. 2.0 × inch
D. 1.0 × inch
The rope's diameter is 10⁻³ inches greater than that of the floss, for example.
The diameter of a stand of rope is 1.2 × 10⁻³ inch.
The diameter of a strand of floss is 2 × 10⁻⁴ inches.
Subtract the diameter of the floss strand from the diameter of the rope to determine how much longer the diameter of the rope is than the diameter of the floss.
Therefore, the length by which the diameter of the strand of rope is longer than the diameter of the strand of floss will be:
= 1.2 × 10⁻³ inch - 2 × 10⁻⁴ inches
Now,
= 12 × 10⁻⁴ inch - 2 × 10⁻⁴ inch
= 10 × 10⁻⁴ inch
= 10⁻³ inch
