Sin A 4/5.
Find
COSA + tan A
Answer:
Step-by-step explanation:
The opposite side (the one not connected to A) = 4
The hypotenuse is 5
The adjacent side needs to be found for the cosine and the tangent.
a^2 + b^2 = c^2
a = opposite side = 4
b = adjacent side = ?
c = hypotenuse = 5
4^2 + x^2 = 5^2
16 + x^2 = 25
x^2 = 25 - 16
x^2 = 9
x = sqrt(9)
x = 3
cos(A) = adjacent / hypotenuse = 3/5
Tan(A) = opposite / adjacent = 4/3
cos(A) + tan(A) = 3/5 + 4/3
cos(A) + tan(A) = 9/15 + 20/15 = 29/15

How do I solve this pls help?
Answer:
a)
f(0) = 4, from the graphb)
h(11) = 15, from the tablec)
g(-9) = -2(-9)² - 4(-9) + 1 = -125, as per equationd)
f(2) = 1, from the graphe)
h(-2) = 2, from the tablef)
g(0.25) = -2(0.25)² - 4(0.25) + 1 = - 0.125, as per equationf(0) = 4
h(11) = 15
g(-9) = -2(-9)² - 4(-9) + 1 = -125
f(2) = 1
h(-2) = 2
g(0.25) = -2(0.25)² - 4(0.25) + 1 = - 0.125

Alan has $115.78 in his savings account. He earns $15.00 cleaning out
the garage and puts $7.50 into savings. He withdrawals $35.90 to buy
a video game. He receives $20 from his grandfather and deposits $15
of it into his savings account. What is Alan's balance now?
Answer:
$137.33
Step-by-step explanation:
$115.78 + $15.00 = $130.78
$130.78 + $7.50 = $138.28
$138.28 - $35.90 = $102.33
$102.33 + $20.00 = $122.33
$122.33 + $15.00 = $137.33

Answer:
1. [tex]\sqrt{218}[/tex]
2. [tex]\sqrt{89}[/tex]
3. [tex]2\sqrt{17}[/tex]
Step-by-step explanation:
The formula to find the distance between any two points on a coordinate plane is as follows:
[tex]D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
Where ([tex](x_1,y_1)[/tex]) and ([tex](x_2,y_2)[/tex]) are the two points one is trying to find the distance between. Substitute the points in and solve for the distance between them for each respective problem.
1.
Points: [tex](-4, 6),\ \ (3, -7)[/tex]
Substitute into the formula,
[tex]D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
[tex]D=\sqrt{((-4)-(3))^2+((6)-(-7))^2}[/tex]
Simplify,
[tex]D=\sqrt{((-4)-(3))^2+((6)-(-7))^2}[/tex]
[tex]D=\sqrt{(-4-3)^2+(6+7)^2}[/tex]
[tex]D=\sqrt{(-7)^2+(13)^2}[/tex]
[tex]D=\sqrt{49+169}[/tex]
[tex]D=\sqrt{218}[/tex]
2.
Points: [tex](-6, -5)\ \ (2,0)[/tex]
Substitute into the formula,
[tex]D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
[tex]D=\sqrt{((-6)-(2))^2+((-5)-(0))^2}[/tex]
Simplify,
[tex]D=\sqrt{((-6)-(2))^2+((-5)-(0))^2}[/tex]
[tex]D=\sqrt{(-6-2)^2+(-5-0)^2}[/tex]
[tex]D=\sqrt{(-8)^2+(-5)^2}[/tex]
[tex]D=\sqrt{64+25}[/tex]
[tex]D=\sqrt{89}[/tex]
3.
Points: [tex](-1, 4)\ \ (1,-4)[/tex]
Substitute into the formula,
[tex]D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
[tex]D=\sqrt{((-1)-(1))^2+((4)-(-4))^2}[/tex]
Simplify,
[tex]D=\sqrt{((-1)-(1))^2+((4)-(-4))^2}[/tex]
[tex]D=\sqrt{(-1-1)^2+(4+4)^2}[/tex]
[tex]D=\sqrt{(-2)^2+(8)^2}[/tex]
[tex]D=\sqrt{4+64}[/tex]
[tex]D=\sqrt{68}[/tex]
[tex]D=2\sqrt{17}[/tex]
Find the distance of the line, then find the slope of the line using the following coordinates (-7,2) and (-4,6)?
Answer:
Distance = 5 units
Slope = [tex]\displaystyle\frac{4}{3}[/tex]
Step-by-step explanation:
Hi there!
1) Finding the distance of the line
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two endpoints of a line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-7,2) and (-4,6):
[tex]d=\sqrt{(-4-(-7))^2+(6-2)^2}\\d=\sqrt{(-4+7)^2+(6-2)^2}\\d=\sqrt{(3)^2+(4)^2}\\d=\sqrt{9+16}\\d=\sqrt{25}\\d=5[/tex]
Therefore, the length of the line/distance of the line is 5 units.
2) Finding the slope of the line
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-7,2) and (-4,6):
[tex]m=\displaystyle\frac{6-2}{-4-(-7)}\\\\m=\displaystyle\frac{6-2}{-4+7}\\\\m=\displaystyle\frac{4}{3}[/tex]
Therefore, the slope of the line is [tex]\displaystyle\frac{4}{3}[/tex].

A segment has endpoints (14,-8) and (4, 12). What are the coordinates of
its midpoint?
Answer:
(9,2)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(14+4)/2 = 18/2 = 9
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(-8+12)/2 = 4/2 = 2

Acme T-Shirt Company charges a $50 set-up fee plus $9 for each shirt printed. Beta T-shirt Company has no set up fee, but charges $14 per shirt. What is the minimum number of shirts for which a customer saves money by using Acme?
Answer:
Step-by-step explanation:
Acme Company:
Let the number of shirts = x
Cost = 50 + 9x
Beta Company:
Cost = 14x
50 + 9x < 14x
Subtract 9x from both sides
50 < 14x - 9x
50 < 5x
Divide both sides by 5
50/5 < x
10 < x
Minimum number of shirts for which a customer saves money by using Acme = 11 T-shirts
Please help me!! Find the equation of the line that is perpendicular to y=1/6x+3 and contains the point (-3,23).
Answer:
[tex]\displaystyle y = -6x + 5[/tex]
Where ? = -6.
Step-by-step explanation:
We want to find the equation of a line that is perpendicular to:
[tex]\displaystyle y = \frac{1}{6} x + 3[/tex]
And contains the point (-3, 23).
Recall that the slopes of perpendicular lines are negative reciprocals of each other.
The negative reciprocal of 1/6 is -6. Hence, the slope of the perpendicular line is -6.
We are also given that it passes through the point (-3, 23). Since we know the slope and a point, we can consider using the point-slope form:
[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]
Substitute:
[tex]\displaystyle y - (23) = -6(x - (-3))[/tex]
Simplify:
[tex]\displaystyle y - 23 = -6 (x+3)[/tex]
Distribute:
[tex]\displaystyle y - 23 = -6x - 18[/tex]
And add. Hence:
[tex]\displaystyle y = -6x + 5[/tex]
In conclusion, our equation is:
[tex]\displaystyle y = -6x + 5[/tex]
Where ? = -6.

The lines shown below are perpendicular. Find the slope-intercept form of the equation of line y2.
Answer:
y = -1/3x + 4
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of each other. The equation for line y1 is 3x - 4 The slope is the coefficient of x, which is 3. That means the slope of line y2 is -1/3, because it's the negative reciprocal. As for the y-intercept, just look for the point on the y-axis that the line intercepts. If we look closely, we can see it intercepts point (0,4) on the y-axis. Therefore, the slope-intercept form equation for line y2 is: y = -1/3x + 4.

what is the answer of this question plzzzzzzzzzzz say fast
Answer:
[tex]1=3=70^{0} \\2=4=5=110^{0}[/tex]
Step-by-step explanation:
Given angle is 110°
Now,
[tex]4=2\,\,and\,\,4=5\,\,;[vertical\,\,angle\,\,and\,\,corresponding\,\,angle\,\,respectively ][/tex]
From the figure,
[tex]4=110^{0}\,\,;[alternate\,\,angle][/tex]
[tex]So,\,\,2=5=110^{0}[/tex]
And, as 1,2,3,4 are vertical angles and 2 = 4 = 110°
1 = 3 = 180° - 110° = 70°

Answer:
angle 1 =70 degrees
angle 2 =110 degrees
angle 3 =70 degrees
angle 4 = 110 degrees
angle 5 =110 degrees
Step-by-step explanation:
1) 110+ angle 1=180(allied angles)
angle 1=180-110
angle 1=70 degrees
2)angle 2+ angle 1=180(angles on a straight line)
angle 2+ 70 =180
angle 2 =180-70
angle 2 =110 degrees
3)angle 3+ angle 2=180(angles on a straight line)
angle 3+ 110 =180
angle 3 =180-110
angle 3 =70 degrees
angle 3 can be taken as vertically opposite angles(70 degrees)4)angle 4 = 110 degrees (vertically opposite angles)
5)angle 5+ angle 3=180(allied angles)
angle 5+ 70 =180
angle 5 =180-70
angle 5 =110 degrees

Answer:
x = 4
Step-by-step explanation:
[tex]-5(x-1)-x+1=-18\\\\-5x+5-x+1=-18\\\\-6x+6=-18\\\\-6x=-24\\\\x=4[/tex]
Answer:
x = 4
Step-by-step explanation:
-5 ( x - 1 ) -x +1 = -18
solve the brackets first
-5x + 5 - x + 1 = -18
-5x -x +5 +1 = -18
-6x + 6 = -18
-6x = -18 - 6
-6x = -24
x = -24 / -6
x = 4
