Answer:
C. T is not one-to-one because the standard matrix A has a free variable.
Step-by-step explanation:
Given
Required
Determine if it is linear or onto
Represent the above as a matrix.
From the above matrix, we observe that the matrix does not have a pivot in every column.
This means that the column are not linearly independent, & it has a free variable and as such T is not one-on-one
Well it all depends what measurement your answer has to be in.
Answer in cm-
12cm stays the same
143m becomes 14,300cm
398km becomes 39,800,000cm
778mm becomes 77.8cm
Then you add them together
12+14,300+39,800,000+77.8=39,814,398.8
The answer stays the same cause it already has the right amount of sig figs so it's 39,814,398.8cm
Answer in m-
12cm becomes 0.12m
143m stays the same
398km becomes 398,000m
778mm becomes 0.778m
Then you add them together
0.12+143+398,000+0.778=398,143.898
But then you have to round to the right amount of sig figs which would be to have two numbers after the decimal point so the answer would then be 398,143.90m
Answer in km-
12cm becomes 0.00012km
143m becomes 0.143km
398km stays the same
778mm becomes 0.000778
Then you add them together
0.00012+0.143+398+0.000778=398.143898km
But then you have to round to the right amount of sig figs which would be to have three numbers after the decimal point so the answer would then be 398.144km
Answer in mm-
12cm becomes 120mm
143m becomes 143,000mm
398km becomes 398,000,000mm
778mm stays the same
Then you add them together
120+143,000+398,000,000+778=398,143,898
The answer stays the same cause it already has the right amount of sig figs so it's 398,143,898mm
Answer:
height of the Eiffel tower ≈ 300.0 m(nearest tenth of a meter)
Step-by-step explanation:
The triangle TDE is not a right angle triangle. Angle TDE can be gotten by subtracting 63° from 180°. Angle on a straight line is 180°. Therefore, 180° - 63° = 117
°.
angle TDE = 117°
angle DTE = 180° - 117° - 31° = 32°
DE = 346.4 m
Side TD can be find using sine law
346.4/sin 32° = TD/sin 31°
cross multiply
346.4 × 0.51503807491 = 0.52991926423TD
178.409189149 = 0.52991926423TD
divide both sides by 0.52991926423
TD = 178.409189149/0.52991926423
TD = 336.672397461
TD ≈ 336.67 m
The side TD becomes the hypotenuse of the new right angle triangle formed with the height of the Eiffel tower.
Using sin ratio
sin 63° = opposite/hypotenuse
sin 63° = h/336.67
cross multiply
h = 336.67 × 0.89100652418
h = 299.975166498
height of the Eiffel tower ≈ 300.0 m(nearest tenth of a meter)
840 km/per hour, because it is traveling 840 km in one hour that is it’s average speed
Answer:
10
Step-by-step explanation:
This equation is in slope-intercept form. Slope-intercept form is
m is the slipe and b in the y intercept if the line. In the equation we are given, 10 is in the place of m, which means 10 is the slioe if the line.
