cos⁻¹ ( 7/23) is the measure of the largest angle.
What is known as a triangle?
The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a single point.
The triangle's three angles add up to a total of 180 degrees.
The lengths are given as a = 725 feet, b = 650 feet, and c = 575 feet.
Since, we know the fact that angle opposite to largest side is greatest. Hence, the largest angle would be opposite to side a.
Now, use the law of cosine
cosA = b² + c² - a²/2bc
On substituting the values, we get
cosA = (650)² + ( 575 )² - ( 725)²/2*650*575
= 422500 + 330625 - 525625/747500
= 227500/747500
= 7/23
A = cos⁻¹ ( 7/23)

find the trapezoidal riemann sum approximation of the integral from 1 to 5 of the square root of quantity x squared plus 3 close quantity times dx using four equal partitions.
Answer:
14.115
Step-by-step explanation:
Recall Trapezoidal Rule
[tex]\displaystyle \int\limits^b_a {f(x)} \, dx=\frac{1}{2}\biggr(\frac{b-a}{n}\biggr)\biggr[f(x_0)+2\bigr(f(x_1)+f(x_2)+\text{... }+f(x_{n-1})\bigr)+f(x_n)\biggr][/tex]
Make necessary substitutions and evaluate
[tex]\displaystyle \int\limits^5_1 {\sqrt{x^2+3}} \, dx=\frac{1}{2}\biggr(\frac{5-1}{4}\biggr)\biggr[2+2\bigr(\sqrt{7}+\sqrt{12}+\sqrt{19}\bigr)+\sqrt{28}\biggr]\approx14.115[/tex]
Note that the actual value of the integral is [tex]\displaystyle \int\limits^5_1 {\sqrt{x^2+3}} \, dx\approx14.078[/tex], so we can see how accurate the Trapezoidal rule is with just a few equal partions.

Tom wishes to purchase a property that has been valued at $300,000. He has $30,000 available as a deposit, and will require a mortgage for the remaining amount. The bank offers him a 25-year mortgage at 2% interest. Calculate his monthly repayments.
Tom's monthly mortgage repayment will be an amount of $1,144.41.
To calculate Tom's monthly mortgage repayment, we can use the formula:
[tex]M = P [ i(1 + i)^n ] / [ (1 + i)^n -1 ][/tex]
Where:
M = monthly repayment
P = the principal amount (loan amount) = $300,000 - $30,000 = $270,000
i = monthly interest rate = 2%/12 = 0.02/12 = 0.0017
n = number of months = 25 years x 12 months/year = 300 months
Plugging in the values:
M = $270,000 [ 0.0017(1 + 0.0017)³⁰⁰ ] / [ (1 + 0.0017)³⁰⁰ – 1 ]
M = $1,144.41
Thus, his monthly mortgage repayment will be $1,144.41.

Chang has two coupons for. A printer coupon a has 14$ rebate on a 75$ printer
Coupon b has 15%off of a 75 $ printer choose the coupon that gives the lower prize
Answer:
The coupon that gives $14 rebate off $75 gives a lower price
Step-by-step explanation:
Let's figure out what percentage of $75 the $14 rebate coupon is
If this percentage is greater than 15% then the $14 rebate coupon gives a better discount; if not the 15% discount offers a better buy
To find what % $14 is of the $75 cost of printer, divide 14 by 75 and multiply by 100 to convert to %:
[tex]\dfrac{14}{75} \times 100 = 18.67\%\\\\[/tex]
Since 18.67% is greater than 15%, getting $14 off $75 will give a lower price

The graph shows a hypothetical relationship between tons of fertilizer used and crop yields. Which statement is NOT correct?img
A) The slope of the curve between one and two tons of fertilizer is approximately 2.
B) The relationship between fertilizer usage and yield is nonlinear.
C) Because the relationship is nonlinear, it is difficult to create an economic model describing the relationship between the two variables.
D) Using more than three tons of fertilizer has minimal effect on yield.
The correct answer is C), because it is possible to create an economic model describing the relationship between fertilizer usage and yield.
The economic model would take into account the nonlinear relationship, which is shown in the graph. Specifically, the slope of the curve between one and two tons of fertilizer is approximately 2 (change in yield divided by change in fertilizer usage). This means that for every ton of fertilizer used, the yield increases by two (change in yield / change in fertilizer usage = 2). Although using more than three tons of fertilizer has minimal effect on yield, the economic model would still take this into account and provide a more accurate representation of the relationship between the two variables.

Answer:
Angle A = 83.59° (2 d.p.)
Angle C = 56.41° (2 d.p.)
Side a = 193.25 (2 d.p.)
Step-by-step explanation:

Given:
b = 125c = 162B = 40°Substitute the given values into the Sine Rule formula:
[tex]\implies \dfrac{\sin A}{a}=\dfrac{\sin 40^{\circ}}{125}=\dfrac{\sin C}{162}[/tex]
Solve for angle C:
[tex]\implies \dfrac{\sin 40^{\circ}}{125}=\dfrac{\sin C}{162}[/tex]
[tex]\implies \sin C=\dfrac{162\sin 40^{\circ}}{125}[/tex]
[tex]\implies C=\sin^{-1}\left(\dfrac{162\sin 40^{\circ}}{125}\right)[/tex]
[tex]\implies C=56.4136175...^{\circ}[/tex]
Interior angles of a triangle sum to 180°. Therefore:
[tex]\implies A+B+C = 180^{\circ}[/tex]
[tex]\implies A = 180^{\circ}-B-C[/tex]
[tex]\implies A = 180^{\circ}-40^{\circ}-56.4136175...^{\circ}[/tex]
[tex]\implies A = 83.5863824...^{\circ}[/tex]
Finally, to find a, substitute the found angles and sides into the Sine Rule and solve for a:

prove that the continuous function of order 3 is continuous of order 1 after being differentiated twice.
We use the concepts of continuity and differentiability to prove that a continuous function of order 3 is continuous of order 1 after being differentiated twice.
Let us assume the function x³ as the function of order 3. We know that its 1st derivative will be 3x² and its 2nd derivative will be, 6x. Now, let's check both of their continuities at any point "a" on the function. By putting a limit x tending to a to the function
= lim (x³) = a³
x→a
and putting a directly to the equation i.e, f(a) = a³ therefore, x³ is a continuous function at a. Similarly, by putting a limit x tending to a to the function
= lim (6x) = 6a
x→a
and putting a directly to the equation i.e, f(a) = 6(a) therefore, 6x is also a continuous function at a. Hence we can say that the continuous function of order 3 is continuous of order 1 after being differentiated twice.
