Hello alrawshdeh04,

Although your answer is completely correct, the question asked "Slope-Intercept form" 

\(y=mx+b\)

\(y=(-\frac{1}{8})(x+8)+1\)

\(y=-\frac{1}{8}x\)

7h^2?

Hello,

Volume: area of the trapezium (\(\frac{b_1+b_2}{2}*h\))=\(\frac{8+5}{2}*4=26\) 

Multiplied by the length (12)

\(26*12=312\) Correct!

Surface:

\((26*2)+(5*12)+(12*4)+(8*12)+(12*5)=316\) 

Correct!

\(I=\frac{PRT}{100}\) where \(I\) is the interest (What you will gain extra after the 2 years) 

\(P\) is the principle (The money you put) 

\(R\) is the rate of 9% etc..

The equation above finds the interest and not the total money! 

Indeed, total money after 2 years is just the same equation +p 

\(A=\frac{PRT}{100}+P\)

Now if you want interest to use this:  \(I=\frac{PRT}{100}\)

\(I=\frac{1500*9*2}{100}=270 \) dollars extra

Total amount: \(270+1500=1770\)

thats not what they asked bruh

Okie dokie i wanted someone to check if i got the answer correct.

SA:316

V:312

**rst=\(-\frac{d}{a}\)

Hints:

Surface area is the sum of areas of all faces (Triangles, rectangles) 

Area of Triangle = \(\frac{1}{2}*b*h\)

Area of Rectangle \(=W*L\)

Volume is the area of the cross-sectional multiplied by the length/height. 

The volume of this shape is the area of the cross-sectional multiplied by the length between the two triangles on the right. (The long dotted line also)

Solution(s):

\(\large{ \begin{array}{|l|l|l|l|l|l|l|l|l|} \hline \mathbf{R}&\mathbf{I_n }&\mathbf{\Delta V_n}&\mathbf{Meas.I_{total}}&\mathbf{R_n}\;\Omega&\mathbf{Calc.I _{total}}&\mathbf{\Delta V_{total}}&\mathbf{R_{eq}}\;\Omega \\ \hline 1&5&15&*&3&5&15&3 \\ \hline 2&2.5&7.5&*&3&2.5&15&6 \\ \hline 3&1.67&5&*&3&5&5&1 \\ \hline \end{array} }\)

Notes:

* The measured current is determined (in a lab setting), using an amp-meter in series with the circuit. The measured current is unique to each circuit, and will typically vary up to \(\pm 20\%\) of the calculated value, depending on the tolerance of the resistors and the power supply.

R3 is three resistors in parallel. If the higher count resistor circuits use a combination of series and parallel resistors, it may be quite tricky to figure out.

Oh, thank you for the help!

It just says undefined on that website 

3.2 x 9.1   x  10^(-28+43)

Use www.mathway.com/precalc

Its a good site calculator.

Power of a point could have come in handy too. Also, could someone help on my question, The one before this post?

You could use intersecting chord theorem:

the diameter chord has   2 segments     8    and   2

the unknown chord has two 2 segments   x   and  x

8*2   =  x*x

16 = x^2             x = 4

Actually, Can SOmEBody Help on C 

I'm not too savvy with number theory, but maybe you could try using the euclidean algorithm with this problem?

First, we realize that the diameter of our given circle O is 10.

That means that the length between O and the intersection with the chord is 3, because:

10-(5+2) = 10 -7 = 3

If we draw two radii to the endpoints of the chord, we get two congruent right triangles by HL congruency(their hypotenuses are both radii of the circle, and they share a common leg). The hypotenuse of one of these right triangles is 5, and their leg is 3(which we just got). To solve for the value of x, we can then write by the pythagorean theorem:

\(5^2 = 3^2 + x^2\)

\(25 = 3^2 + x^2\)

\(25 = 9 + x^2\)

\(16 = x^2\)

Square rooting both sides and discarding the negative solution(a length can't be negative), we arrive at our answer of:

\(x = 4\)

Alternatively, we can realize that the triangle created is a 3-4-5 triangle(through memorization of right triangles), which would be a faster way to calculate the length without going into pythagorean.

a=1; b=1;c=gcd((a^3+b^3)/(a+b), (a*b)); if(c==9 and a-b==6, goto4, goto5);printc, a, b; a++;if(a<100, goto2, 0);a=1;b++;if(b<100, goto2, discard=0;

OUTPUT:  a = 9   and   b = 3

NEVERMIND, looking at the picture gave me a brainwave and I solved it easily. EHEHEHHEHEHHEHEHHHEEEEEEE! SORRy Im JusT a BiT TIReD RIghtT Now.

The Heading of his/her question says "Simple Interest".

1500 x 0.09 x 2 =$270 Simple interest for 2 years.

$1,500  +  $270  = $1,770 - Balance after 2 years.
