Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º. Scarlett's height is 1.65 meters, so the height of the dam is meters. NextReset
Answer:
The height of dam =45.5 m.
Step-by-step explanation:
We are given that Scarlett stands 90 m away from the dam and records the angle of elevation to the top of the dam to be [tex]26^{\circ}p[/tex]
Scarelett's height is 1.65 meters.
We have to find the height of the dam.
Let h be the height of dam
AC=AB+BC
BC=x
h=1.65+x
CD=EB=90 m
In triangle ABE
[tex]\theta=26^{\circ}[/tex]
[tex]tan\theta=\frac{perpendicular\;side}{Base}[/tex]
[tex]tan26^{\circ}=\frac{AB}{90}[/tex]
[tex]0.4877=\frac{x}{90}[/tex]
[tex]x=0.4877\times 90[/tex]
[tex]x=43.893 m[/tex]
Therefore, the height of dam=1.65+43.893=45.543 m
Answer: The height of dam =45.5 m

Find two numbers that multiply to make the first number and add to make the second number. (I understand how to do it, I’m just having some issues. It’s not registering.)
The student's question pertains to solving a system of equations to find two numbers that multiply to a given product and add to a given sum. The solution involves testing pairs of factors of the product until the pair that also sums to the required number is found, for example, finding that 3 and 8 multiply to 24 and add to 11.
The student is looking to solve a classic problem in algebra: finding two numbers that, when multiplied together, result in a given number (the product), and when added together, sum to another given number (the sum). This is often related to factoring a quadratic equation or finding the roots of a polynomial. The solution involves setting up a system of equations based on the given conditions and solving for the two unknown numbers. This process typically requires identifying the correct pair of numbers that satisfy both the multiplication and addition conditions. Let's take an example:
Suppose we need to find two numbers that multiply to make 24 and add to make 11. We can denote these numbers as x and y, leading to the following equations:
x . y = 24 (multiplication condition)x + y = 11 (addition condition)By systematically testing pairs of factors of 24 (e.g., 1 and 24, 2 and 12, 3 and 8, 4 and 6), we find that 3 and 8 satisfy both conditions, because 3 . 8 = 24 and 3 + 8 = 11. Therefore, the two numbers are 3 and 8.
Use the equation and type the ordered-pairs.

Answer: [tex](-1,\frac{1}{3}),\ (0,1),\ (1,3),\ (2,9),\ (3,27),\ (4,81)[/tex]
Step-by-step explanation:
The given exponential function :
[tex]y=3^x[/tex]
At x = -1, we get
[tex]y=3^{-1}=\dfrac{1}{3}[/tex]
At x = 0, we get
[tex]y=3^{0}=1[/tex]
At x = 1, we get
[tex]y=3^{1}=3[/tex]
At x = 2, we get
[tex]y=3^{2}=9[/tex]
At x = 3, we get
[tex]y=3^{3}=27[/tex]
At x = 4, we get
[tex]y=3^{4}=81[/tex]
Hence, the completed ordered pairs are : [tex](-1,\frac{1}{3}),\ (0,1),\ (1,3),\ (2,9),\ (3,27),\ (4,81)[/tex]

What are the zeros of the quadratic function f(x) = 8x2 – 16x – 15? x = –1 – and x = –1 + x = –1 – and x = –1 + x = 1 – and x = 1 + x = 1 – and x = 1 +
To find the zeros of the quadratic function [tex]\( f(x) = 8x^2 - 16x - 15 \)[/tex], you need to solve for [tex]\( x \) when \( f(x) = 0 \)[/tex].
So, you set \( f(x) \) equal to zero:
[tex]\[ 8x^2 - 16x - 15 = 0 \][/tex]
To solve this quadratic equation, you can use the quadratic formula:
[tex]\[ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} \]where \( a = 8 \), \( b = -16 \), and \( c = -15 \).[/tex]
Plugging these values into the quadratic formula:
[tex]\[ x = \frac{{-(-16) \pm \sqrt{{(-16)^2 - 4(8)(-15)}}}}{{2(8)}} \]\[ x = \frac{{16 \pm \sqrt{{256 + 480}}}}{{16}} \]\[ x = \frac{{16 \pm \sqrt{{736}}}}{{16}} \][/tex]
Now, you simplify the expression under the square root:
[tex]\[ \sqrt{736} = \sqrt{16 \times 46} = 4\sqrt{46} \][/tex]
So, the expression becomes:
[tex]\[ x = \frac{{16 \pm 4\sqrt{46}}}{{16}} \][/tex]
Now, you can simplify further:
[tex]\[ x = \frac{{4(4 \pm \sqrt{46})}}{{4 \times 4}} \]\[ x = \frac{{4 \pm \sqrt{46}}}{{4}} \][/tex]
This gives you two solutions:
[tex]\[ x = \frac{{4 + \sqrt{46}}}{{4}} \]\[ x = \frac{{4 - \sqrt{46}}}{{4}} \][/tex]
These are the zeros of the quadratic function [tex]\( f(x) = 8x^2 - 16x - 15 \).[/tex]

Bill takes a loan of 9,000.00 at a 8% simple interrst rate for 6 years a.how much interest will he pay after 2 years? b. how much interest will he pay in total for the loan
help plz
Bill will pay an interest of $1440 after 2 years and a total interest of $4320 over 6 years.
Explanation:The subject of your question is related to simple interest calculation. The formula to calculate the simple interest is I = P * R * T, where I is the interest, P is the principal amount (initial loan), R is the annual interest rate in decimal form and T is time in years.
So when you ask 'how much interest will Bill pay after 2 years?', you plug in your values as follows: I = $9000 * 0.08 * 2 which calculates to $1440.
For the total interest Bill will pay over the 6 years, we substitute the values into the formula again but this time T = 6. So, I = $9000 * 0.08 * 6 which calculates to $4320.

Bill will pay $1,440.00 in interest after 2 years and a total of $4,320.00 in interest for the entire loan period of 6 years.
Simple interest can be calculated using the formula Interest = Principal × Rate × Time (I = PRT).
Part A: Interest After 2 YearsThe principal amount is $9,000.00, the interest rate is 8%, and the time is 2 years.
Interest = 9,000 × 0.08 × 2 = 1,440Bill will pay interest of $1,440.00 after two years.
Part B: Total Interest for the LoanAgain, using the same formula but for 6 years:
Interest = 9,000 × 0.08 × 6 = 4,320Bill will pay a total of $4,320.00 in interest over the entire loan period.

If your credit score is 750, how much will you pay in interest by the end of 1 month if you owe $2,375.00?
$31.17
$24.74
$18.31
$11.38,
Answer:
$18.31
Step-by-step explanation:
Credit score = 750
Period (n) = 1 month
Debt = $2375
Since the score is 750, from the table annual rate = 9.25%
Monthly rate (r) = 9.25/12 = 0.7708%
Interest =.PRT/100
P= principal amount
R= rate
T = time taken
Interest = (2375*0.7708*1)/100
= 18.6065

A rectangle has a length of the cube root of 81 inches and a width of 3 to the 2 over 3 power inches.
i.e. let 'l' and 'b' denote the length and width of the rectangle.
i.e.[tex]l=\sqrt[3]{81}\\\\l=(3^4)^{\dfrac{1}{3}}\\\\l=3^{\dfrac{4}{3}[/tex]
since,
[tex](a^m)^n=a^{mn}[/tex]
and
[tex]w=3^{\dfrac{2}{3}}[/tex]
Hence, the area of rectangle is given by:
[tex]Area=l\times w\\\\\\Area=3^{\dfrac{1}{3}}\times3^{\dfrac{4}{3}}\\\\\\Area=3^({\dfrac{1}{3}+\dfrac{4}{3}})\\\\\\Area=3^{\dfrac{6}{3}}\\\\\\Area=3^2\\\\\\Area=9\ square\ inches[/tex]

[tex]\dfrac{a^m}{a^n}=a^{m-n}[/tex] )
Hence, the correct answer is: Option: c
Ques 3)
The cube root of 2 to the seventh power.
i.e.

Step-by-step explanation:
Andrew has a coupon for $2.80 puppy treats. One bag of treats usually costs $9.94 and contains 42 of the treats. If Andrew uses his coupon what will be the price per puppy treats
Andrew's price per puppy treat, after using a $2.80 coupon on a $9.94 bag that contains 42 treats, will be $0.17.
Andrew has a coupon that will reduce the price of puppy treats. Without the coupon, one bag of treats costs $9.94 and contains 42 treats. To find the price per treat after using the $2.80 coupon, we first subtract the coupon value from the original price of the bag. This gives us the discounted price of the bag:
Discounted Price = Original Price - Coupon Value = $9.94 - $2.80 = $7.14
Next, we find the price per treat by dividing the discounted price of the bag by the number of treats in the bag:
Price per Treat = Discounted Price ÷ Number of Treats = $7.14 ÷ 42 = $0.17 (rounded to two decimal places)
After using the coupon, the price per puppy treat will be $0.17.

This figure shows circle A with inscribed ∠RSQ .
m∠RSQ=24°
What is the measure of RSQ?
For a better understanding of the solution and the explanation given here please go through the diagram in the file attached.
By definition, measure of an arc is the angle subtended by the arc at the centre of the circle. Thus, the measure of the arc [tex] \overarc {RSQ} [/tex] is the measure of the [tex] \angle RAQ [/tex] (in red) which the arc [tex] \overarc {RSQ} [/tex] subtends at the center.
Now, in order to find the measure of the [tex] \angle RAQ [/tex] (in red) we will have to use the information given in the question. We have been told that [tex] m\angle RSQ=24^{\circ} [/tex]. Now, we know that the double angle theorem says that, the angle subtended at the centre of a circle is double the size of the angle subtended at the circumference from the same two points. Therefore, applying this theorem we get:
[tex] \angle RAQ =2\times 24^{\circ}=48^{\circ} [/tex]
Thus if [tex] \angle RAQ [/tex] (in red)=[tex] 48^{\circ} [/tex], then [tex] \angle RAQ [/tex] (in green) will be equal to measure of the arc [tex] \overarc {RSQ} [/tex]. Now, [tex] \angle RAQ [/tex] (in green) will obviously be:
[tex] \angle RAQ [/tex] (in green)=[tex] 360^{\circ}-\angle RAQ [/tex] (in red)
[tex] \angle RAQ [/tex] (in green)=[tex] 360^{\circ}-48^{\circ} [/tex]
[tex] \angle RAQ [/tex] (in green)=[tex] 312^{\circ} [/tex]
Thus, the measure of arc [tex] \overarc {RSQ} [/tex]=[tex] 312^{\circ} [/tex]

In the previous problem, Ken predicted a drop in temperature. Explain why a drop in temperature would lead to adding a negative integer.
Answer:
Because a drop in temperature means decrease in temperature therefore, we take an integer with negative sign and added to previous temperature.
Step-by-step explanation:
Drop in temperature means decrease in the temperature .When the temperature decreases then we take decrease value of temperature in negative integer. Because decrease means the temperature fall down .Hence , the decrease in temperature measure with negative sign .
For example, if we take temperature T= 70°C.
If the temperature decreases by 5°c then the temperature
Decrease in temperature=-5°C
Hence, the temperature T= 70+(-5)=65°C.
Therefore , from example we can say that when temperature decreases by some value in integer . Then ,we get final temperature obtained by adding drop in temperature ( negative integer ) in previous value of the temperature.
