Answer:
draw a right angle triangle
Step-by-step explanation:
Let one of the angles be A
cos A = sin (90-A)
90 - x - 20 = x
2x = 70
x = 35 degrees
Five cats each had 5 kittens. The cats and kittens each had 5 fleas. Each flea had 5 tiny spiders on it. How many legs are there all together?
Answer:
5 cats times 4 legs = 20
5 kittens times 4 legs =20
5 fleas times 5 cats = 25
5 fleas times 5 kittens = 25
5 tiny spiders times 5 fleas = 25
20+20+25+25+25= 115
115 legs altogether
Answer:
yup 115 legs
Step-by-step explanation:
find c and round to the nearest tenth
Answer:
Step-by-step explanation:
<C = ?
a = 22
b = 20
c = 18
Formula
c^2 = a^2 + b^2 - 2*a*b* cos(C)
Solution
18^2 = 22^2 + 20^2 - 2*22*20*cos(C)
324 = 484 + 400 - 880*cos(C)
324 = 884 - 880*Cos(C)
-560 = - 880 * cos(C)
-560 / - 880 = cos(C)
0.63636 = cos(C)
C = cos-1(0.63636)
C =50.48
Answer:
20
Step-by-step explanation:
this equality contains a viable 3(23+18)<6a
[tex]3(23+18) < 6a \\ 41 < 2a \\ a > 41/2\implies a > 20.5[/tex]
Hope this helps.
Answer: a >41/2
Step-by-step explanation: Step 1: Simplify both sides of the inequality.
123<6a
Step 2: Flip the equation.
6a>123
Step 3: Divide both sides by 6.
6a/6>123/6
a>41/2

Megan’s TV had a base price of $189 and the sales tax was 6.88%. Over the next four years, the TV consumed an average of $0.06 of electricity every day. It also needed repairs twice, costing $29 each time. After four years, Megan got a new TV. What was the lifetime cost of Megan’s TV? (Remember that one in every four years is a leap year.)
a.
$357.68
b.
$318.66
c.
$347.66
d.
$351.65
Answer:
Step-by-step explanation:
price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00
4 years = 3×365 days + 366 days = 1461 days
cost of electricity = 1461 days × $0.06/day = $87.66
lifetime cost = purchase price + electricity + repairs
= $202.00 + $87.66 + 2·$29
= $347.66
Answer:
347.66 is your answer

Tyler is observing the ascent of a
steel beam being lifted by a crane
from a position about 250 feet
away. What function models the
height h in feet of the beam as a
function of the angle of inclination
from Tyler's position to the steel
beam?
Answer:
Step-by-step explanation:
tanθ = h/250
h = 250tanθ
The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ feet
What is angle of inclination?"The angle inclination of a line is the angle formed by the intersection of the line and the x-axis."
What are trigonometric functions?"The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths."
We have
Adjacent side = 250 feet
From the figure,
We can write trigonometric function
Tanθ = [tex]\frac{AB}{BC}[/tex]
Tanθ = [tex]\frac{h}{250}[/tex]
⇒ h = 250 tanθ feet
Hence, The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ

A function, f(x), passes through the point (0,2). Another function is represented by the equation g(x)=x^2−2x−3. What is the y-intercept of g(x) and which function has the greater y-intercept
Answer:
The y-intercept of function f(x) is 2.The y-intercept of function g(x) is -3.Therefore, we conclude that function f(x) has a greater y-intercept.
Step-by-step explanation:
The y-intercept of any function can be determined by checking the value of y at x = 0.
Important Tip
A point where the graph meets the y-axis — y-intercept.Determining the y-intercept of the function f(x)
Given the function f(x) passes through the point (0,2).
It means at x = 0, the value of y = 2
Thus, the y-intercept of function f(x) is 2.
Determining the y-intercept of the function g(x)
Given the function g(x)
[tex]g\left(x\right)=x^2-2x-3[/tex]
substitute x = 0 in the function equation
[tex]g\left(0\right)=\left(0\right)^2-2\left(0\right)-3[/tex]
[tex]g\left(0\right)=0-0-3[/tex]
[tex]g\left(0\right)=-3[/tex]
It means at x = 0, the value of y = -3
Thus, the y-intercept of function g(x) is -3.
Conclusion:
The y-intercept of function f(x) is 2.The y-intercept of function g(x) is -3.As 2 > -3
Therefore, we conclude that function f(x) has a greater y-intercept.

Find the general solution of (x+3)y’=2y
Answer:
[tex]y=C(x+3)^2[/tex]
Step-by-step explanation:
We are given:
[tex]\displaystyle (x+3)y^\prime=2y[/tex]
Separation of Variables:
[tex]\displaystyle \frac{1}{y}\frac{dy}{dx}=\frac{2}{x+3}[/tex]
So:
[tex]\displaystyle \frac{dy}{y}=\frac{2}{x+3} \, dx[/tex]
Integrate:
[tex]\displaystyle \int\frac{dy}{y}=\int\frac{2}{x+3}\, dx[/tex]
Integrate:
[tex]\displaystyle \ln|y|=2\ln|x+3|+C[/tex]
Raise both sides to e:
[tex]|y|=e^{2\ln|x+3|+C}[/tex]
Simplify:
[tex]|y|=(e^{\ln|x+3|})^2\cdot e^C[/tex]
So:
[tex]|y|=C|x+3|^2[/tex]
Simplify:
[tex]y=\pm C(x+3)^2=C(x+3)^2[/tex]
