Answer:
7.45feet
Step-by-step explanation:
The set up will give a right angled triangle
Height of the ladder is the hypotenuse = 7 feet
Angle of elevation= 70 degrees
Required
Distance up the building you will be able to reach (Length of the ladder) which is he hypotenuse
Using SOH in trigonometry identity;
Sin 70 = opposite/hypotenuse
Sin 70 = 7/hyp
hyp = 7/sin70
hyp = 7/0.9397
hyp = 7.45 feet
Hence the will be able to go 7.45feet
state the equation of the line in y = mx + b form.
How do you get the equation of the line in fully simplified slope-intercept form?
Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4
Find the equation of the line
passing through the points (2,11)
and (-8,-19).
y = [ ? ]x + [ ]
Given:
A line passes through two points are (2,11) and (-8,-19).
To find:
The equation of the line.
Solution:
The line passes through two points are (2,11) and (-8,-19). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-11=\dfrac{-19-11}{-8-2}(x-2)[/tex]
[tex]y-11=\dfrac{-30}{-10}(x-2)[/tex]
[tex]y-11=3(x-2)[/tex]
Using distributive property, we get
[tex]y-11=3(x)+3(-2)[/tex]
[tex]y-11=3x-6[/tex]
Adding 11 on both sides, we get
[tex]y=3x-6+11[/tex]
[tex]y=3x+5[/tex]
Therefore, the equation of line is [tex]y=3x+5[/tex]. So, the missing values are 3 and 5 respectively.
Answer: 3x+5

Answer:
27/8
Step-by-step explanation:
first you would convert -.5 to -1/2 and add everything up by getting the same denominator
Answer:
3.375
Step-by-step explanation:First convert the 2 1/4 and the 1 5/8
then you just add it with the 0.5 or just use a calculator
2 1/4 = 9/4
1 5/8= 13/8
okay now do this ---> 0.5 + 9/4 +13/8 =3.375
f(x) = -x^2 + 6x + 4 find f(-7)

The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.
