Which equation represents the line shown on the coordinate plane below??
A straight line is represented by a linear function.
The equation of the line is [tex]y = -\frac 14 x[/tex]
From the coordinate plane, the line passes through the following points
[tex](x,y) =(0,0)\ (4,-1)[/tex]
The slope of the above points is calculated using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, the above equation becomes
[tex]m = \frac{-1 - 0}{4-0}[/tex]
This gives
[tex]m = \frac{-1}{4}[/tex]
Rewrite as:
[tex]m = -\frac{1}{4}[/tex]
The line equation is then calculated as:
[tex]y = m(x-x_1) + y_1[/tex]
So, we have:
[tex]y = -\frac 14 (x-0) + 0[/tex]
This gives
[tex]y = -\frac 14 (x)[/tex]
Remove bracket
[tex]y = -\frac 14 x[/tex]
Hence, the equation of the line is [tex]y = -\frac 14 x[/tex]

Take the second derivative, utilizing quotient and chain rule.
[tex] {g}^{'} = - \frac{8}{(2x - 1)^{3} } \\ {g''} = \frac{48}{(2x - 1)^{4} } \\ {g''(1)} = \frac{48}{(2(1) - 1)^{4} } = \frac{48}{1} = 48[/tex]
Find the area of the trapezoid. Pls explain and I will mark brainliest.
Answer:
B. 191.4 m²Step-by-step explanation:
Split the trapezoid as pictured below
Find its height and the upper base, then find the area of the trapezoid.
There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles
The ratio of sides of a 30°×60°×90° triangle is 1 : √3 : 2The legs of a 45x45 triangle are equalThe above mentioned properties give us:
h = 16/2 = 8 m b = 8√3 ≈ 13.85 ma = h = 8 mNow find the area:
A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²Correct choice is B
Find the volume of the figure
Answer:
38m
Step-by-step explanation:
you have to split this composite shape into two separate shapes; two rectangles.
To work out the area of the bigger rectangle, you have to do 6×5=30m
Then to work out the smaller rectangle you do 2×4=8m
So, as we want the total area of the shape you would have to add up the two areas together.
30+8=38m

Answer:
[tex] \tan (A +B) = - 6\frac{6}{13} [/tex]
Step-by-step explanation:
[tex] \sin \: A = \frac{3}{5}...(given) \\ \\ \because\cos A = \pm \sqrt{1 - { \sin }^{2}\: A } \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \bigg( \frac{3}{5} \bigg) ^{2}} \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \frac{9}{25}} \\ \\ \therefore\cos A = \pm \sqrt{ \frac{25 - 9}{25} } \\ \\ \therefore\cos A = \pm \sqrt{ \frac{16}{25}} \\ \\ \therefore\cos A = \pm { \frac{4}{5}} \\ \\ \because \: \angle A \: is \: in \: quadrant \: I \\ \\ \therefore \: \cos A = { \frac{4}{5}} \\ \\ \tan \: A = \frac{ \sin \: A}{\cos \: A} \\ \\ \tan \: A = \frac{ \frac{3}{5} }{ \frac{4}{5} } \\ \\ \tan \: A = \frac{3}{4} \\ \\ \because \tan (A +B) = \frac{ \tan A + \tan B }{1 - \tan A \tan B } \\ \\ \therefore \tan (A +B) = \frac{ \frac{3}{4} + \frac{15}{8} }{1 - \frac{3}{4} \times \frac{15}{8} } \\ \\ \therefore \tan (A +B) = \frac{ \frac{6}{8} + \frac{15}{8} }{1 - \frac{45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{32 - 45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{ - 13}{32}} \\ \\ \therefore \tan (A +B) = \frac{21}{8} \times \bigg(- \frac{32}{13 } \bigg)\\ \\ \therefore \tan (A +B) = - \frac{84}{13} \\ \\ \therefore \tan (A +B) = - 6\frac{6}{13} [/tex]

Answer:
Step-by-step explanation:
-3x+4y=4
-5x-3y=26
----------------
-8x+y=30
y=8x+30
Plug 8x+30 back into -5x-3y=26
-5x-3(8x+30)=26
-5x-24x+90=20
-29x=-70
x=2.413
Plug 2.413 into y=8x+30
y=8(2.413)+30
y=19.304+30

Jhon jogged 5 Miles on Thursday 6 to 50 miles on Friday and 3.4 miles on Saturday how many miles does Jhon have to run in order to run 70 miles for the week _ per week.
Answer:
8 miles
Step-by-step explanation:
If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.
70÷50=1.4
So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:
1.4 minutes mile × 5 miles = 7 minutes
Thus it will take her 7 minutes to run 5 miles at this pace.
If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.
If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
