Slope intercept form is y=mx+b where m is the slope and b is the y intercept. we have the slope is -6 and a point so the beat way to solve is to use point slope form and si.plify this into y intercept forn.
point slope is (y-y1)=m(x-x1) where (x1,y1) is a point o. the line. so we get
(y-8)=-6(x-(-2))
y-8=-6(x+2)
y-8=-6x-12
y=-6x-4
now we have slope intercept form!
412.638 using expanded form using decimals is :
4 x 100 + 1 x 10 + 2 x 1 + 6 x 0.1 + 3 x 0.01 + 8 x 0.001 Hope this helped you!
Answer:
1. ∠A = 71.9°
2. ∠B = 62.9°
3. ∠C = 27.5°
Step-by-step explanation:
By using a calculator, we have;
cos A = 0.31
sin B = 0.89
tan C = 0.52
1. Therefore, ∠A = cos⁻¹(0.31), inputting the digits in the calculator and looking for the inverse sign, we have;
∠A = cos⁻¹(0.31) = 71.94° = 71.9° to the nearest tenth of a degree.
2. For sin B = 0.89, we have;
∠B = sin⁻¹0.89 = 62.873° ≈ 62.9° with the answer rounded to the nearest tenth of a degree.
3. Similarly, for tan C = 0.52, inputting the values in the calculator and pressing the tan⁻¹ button, we have;
∠C = tan⁻¹(0.52) = 27.474°, which is 27.5° rounded to the nearest tenth of a degree.
Answer:
area of circle=π![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
452.1=3.14![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
452.1/3.14=![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
143.98=![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
=r
11.99=r
now ,
diameter=2r
=2*11.99
=23.98
