Solve the following equation: -3 = 1 3/5 + m.
-2 3/5
-4 3/5
-4 2/5
-1 2/5
Answer:
-4 3/5
Step-by-step explanation:
I subtracted 1 3/5 from -3 and got -4 3/5. I also added 1 3/5 + -4 3/5 to check my work and it is correct.

If cos -105º = -0.26 and csc -105º = -1.03, then cos 105º = ? and csc 105º = ?
Answer:
[tex]\cos(105^\circ)\approx-0.26\text{ and } \csc(105^\circ)\approx1.03[/tex]
Step-by-step explanation:
We are given that:
[tex]\cos(-105^\circ)\approx-0.26\text{ and } \csc(-105^\circ)\approx-1.03[/tex]
And we want to find:
[tex]\cos(105^\circ)\text{ and } \csc(105^\circ)[/tex]
Part A)
Remember that cosine (and secant) is an even function. By definition, this means that:
[tex]\cos(\theta^\circ)=\cos(-\theta^\circ)[/tex]
Therefore, since we know that cos(-105°) is about -0.26, it follows from the definition that:
[tex]\cos(-105^\circ)=\cos(105^\circ)\approx-0.26[/tex]
Part B)
Remember that cosecant (and sine) is an odd function. By definition, this means that:
[tex]\csc(-\theta^\circ)=-\csc(\theta^\circ)[/tex]
We know that csc(-105°) is about -1.03.
By the above definition, we can rewrite csc(105°) as csc(-(-105°)) or -csc(-105°).
Hence, it follows that:
[tex]\csc(105^\circ)=-\csc(-105^\circ)=-(-1.03)=1.03[/tex]
A map of Utah has a scale of 1 cm: 30 mi. The border of Utah measures
about 3.7 cm. How long is the actual border of Utah and Wyoming? Show
your work to receive full credit
Answer:
The actual border of Utah and Wyoming is 111 miles long.
Step-by-step explanation:
We can use proportion to solve this!
[tex] \frac{1 \: cm}{30 \: mi} = \frac{3.7 \: cm}{x} \\ \\ \frac{111}{1} = \frac{1x}{1} \\ \\ 111 = x[/tex]

The total surface area of a cone whose radius is 2 r and slant height 2l is
(A) 2πr (l + r)
(B) πr (l + 4 r )
(C) πr (l + r)
(D) 2πrl
please answer urgent
Answer:
[tex]A=4\pi r(l+r)[/tex]
Step-by-step explanation:
The total surface area of a cone is given by :
[tex]A=\pi rl+\pi r^2\\\\=\pi r(l+r)[/tex]
Put r = 2r and l = 2l in the above formula
[tex]A=\pi \times 2r(2l+2r)\\\\A=2\pi r(2l+2r)\\\\=2\pi r \times 2(l+r)\\\\=4\pi r(l+r)[/tex]
Hence, the total surface area of the cone is [tex]4\pi r(l+r)[/tex].

Been stuck on this for hours, it's the Law of Sines. 25 POINTS!!
Answer:
Step-by-step explanation:
(Sin27) / 11 = (sin x) / 15
cross multiply
15 sin27 = 11 sin x
keep in calculator as you divide 15sin27 by 11.
sin x = .6190779542
do sin ^ -1 (.6190779542) (It’s a key on the calculator.)
x = 38.25*
9514 1404 393
Answer:
38.2°
Step-by-step explanation:
According to the equation you are give, ...
sin(x)/15 = sin(27°)/11
Multiplying by 15 gives you ...
sin(x) = 15·sin(27°)/11 ≈ 0.619078
The inverse sine function is used to find the angle x. It may show as sin⁻¹ on your calculator.
x = arcsin(0.619078)
x ≈ 38.2°
_____
Additional comment
x is shown in the figure as an acute angle, so that is the value we have chosen. The other angle that has sin(x) = 0.619078 is the supplement of this, or 141.8°. The two solutions are shown in the 2nd and 3rd attachments.
