Answer:
-2
Step-by-step explanation:
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Given
Slope = -3
Get the intercept c;
Substitute m = -3 and (1, -9) into y = mx+c
-9 = -3(1) + c
-9 = -3 + c
c = -9 + 3
c = -6
The equation becomes
y = -3x + (-6)
y = -3x-6
f(x) = -3x-6
The zero of f occurs at f(x) = 0
0 = -3x-6
3x = -6
x = -6/3
x = -2
Hence the zero of the function is -2
Answer:

Step-by-step explanation:
Answer:
y = 0.8x + 4
Step-by-step explanation:
The slope is 0.8 and y intercept is 4.
Answer:
1.
Step-by-step explanation:
1) if sin30=0.5; tan45=1; tan30=1/√3; sin60=√3/2, then
2) 0.5+0.5=1.
Answer:
<h2>
351.88 m</h2>
Step-by-step explanation:
Given,
D = diameter of semicircular part = 42 m
L = Length of straight part = 110 m
Now, let's find the perimeter:
= 2 ( length of semi-circle + length of straight part )
![= 2( \frac{\pi \: d}{2} + l)](https://tex.z-dn.net/?f=%20%3D%202%28%20%5Cfrac%7B%5Cpi%20%5C%3A%20d%7D%7B2%7D%20%20%2B%20l%29)
Plug the values
![= 2( \frac{3.14 \times 42}{2} + 110)](https://tex.z-dn.net/?f=%20%3D%202%28%20%5Cfrac%7B3.14%20%20%5Ctimes%2042%7D%7B2%7D%20%20%2B%20110%29)
Calculate the product
![= 2( \frac{131.88}{2} + 110)](https://tex.z-dn.net/?f=%20%3D%202%28%20%5Cfrac%7B131.88%7D%7B2%7D%20%20%2B%20110%29)
Divide
![= 2 (65.94 + 110)](https://tex.z-dn.net/?f=%20%3D%202%20%2865.94%20%2B%20110%29)
Calculate the sum
![= 2 \times 175.94](https://tex.z-dn.net/?f=%20%3D%202%20%5Ctimes%20175.94)
Calculate
![= 351.88 \: m](https://tex.z-dn.net/?f=%20%3D%20351.88%20%5C%3A%20m)
Hope this helps..
Best regards!!
