Answer:

Okay so all you have to do is find the Area of each shape, then add them together.  Starting with the square.  Your formula is A=s4    All you have to do is plug in your number.  A=26(4) Now solve. A=104.   Now we have to find the area of a semicircle.  Your formula is ((3.14)r squared)(.5) To find the radius (r) you divide the diameter by 2, so 26/2=13     Now all you have to do is plug in your numbers.   (3.14)(13 squared)(.5)    (3.14)(169)(.5)   

(530.66)(.5)   Your final answer is:  265.33 inches squared

Explain how you find a slope from a table a graph and an equation
RoseWind [281]

Answer:

we know that

To calculate the slope we need to take two points from data in a table

point 1 (x1,y1) and point 2(x2,y2)

The formula to calculate the slope between two points is equal to

substitute the values and solve for m

Can some show the steps and the answer please I really need help tell me how you get it and the answer
Tems11 [23]

Answer:

Step-by-step explanation:

here is some helpful trig function reminders.. copy this and keep it

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

they ask how long is the ladder

they give us the opposite side (8) and the adjacent side (6)  

and the Hyp is the length of the ladder.   They expect you to sort this out in your head.  :/  

there is two steps .. we'll solve for the angle.. then we can use that to find the Hyp side..(long side of triangle)  which is the ladder length

Tan(Ф) = Opp / Adj

Tan(Ф) = 8 / 6

Ф = arcTan(8 / 6)

Ф ≈ 53.130°

now lets use that angle with one of the other trig functions to find the Hyp.. sin or cos will work b/c we have both the opp and the adj sides lengths.  let's use cos

Cos(53.130) = 6 / Hyp

Hyp = 6 / Cos(53.130)   ( I just used algebra to swap the two)

Hyp = 9.99997

the ladder will be 10' long.  

ask in the comments if you need any more explaining

the length of diagonal of a rectangular field is 23.7 m and one of its sides is 18.8 m. find the perimeter of the field.​
katen-ka-za [31]

Answer:

Approximately 66.4 Meters

Step-by-step explanation:

So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.

a^2+b^2=c^2

Plug in 18.8 for either <em>a </em>or <em>b. </em>Plug in the diagonal 23.7 for <em>c. </em>

<em />(18.8)^2+b^2=23.7^2\\b^2=23.7^2-18.8^2\\b=\sqrt{23.7^2-18.8^2} \\b\approx14.4 \text{ meters}

Therefore, the length is 14.4 meters. Now, find the perimeter:

P=2l+2w\\P=2(14.4)+2(18.8)\\P=66.4\text{ meters}
