The center of this triangle is created by intersection of altitudes of the triangle, so this point T is an orthocenter.
So, the answer is A.
2 : 7<span> = 4 : 14 if we multiply both sides by 2, and (writes) : = </span>1 : 3.5<span> if we divide both sides by 2.</span>
Answer:
0; 10; 20
Step-by-step explanation:
x is the independent variable
y is the dependent variable
y is dependent on x
a) For what value of the independent variable will the value of the function be equal to −6
y=0.3x−6
-6 = 0.3x-6
0=0.3x
x = 0
Therefore, if the independent variable is 0, the value of the function will be -6.
b) For what value of the independent variable will the value of the function be equal to −3
y=0.3x−6
-3 = 0.3x-6
0.3x = -3+6
0.3x = 3
x = 3/0.3
x = 10
Therefore, if the independent variable is 10, the value of the function will be -3.
c) For what value of the independent variable will the value of the function be equal to 0.
y=0.3x−6
0=0.3x-6
6 = 0.3x
x = 6/0.3
x = 20
Therefore, if the independent variable is 20, the value of the function will be 0.
2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4
Answer:
Marcus ran at a pace of 7.40 miles an hour
Joseph was running at a pace of 7.43 miles an hour
Harper was running at a speed of 7.06 miles an hour
And Nikki was running at a speed of 6.42 miles an hour
Step-by-step explanation: The fastest per mile would be joseph because he was running the fastest MPH
