garri49 [273]3 years ago
3 0

Answer:

ans b is the correct answer because

first we should have to multiply 1.4×10 power 6 which means 14000000 km

then we should divide with mars diameter which is 7000 km

14000000/7000km= 2× 10 power 3

2× 10 power 3

2×1000

therefore 2000 km is the ans

hope you understand

plz give me brainliest+ thanks. i need to reach in expert. : )

Calculate the area of the shaded sector in the circle​
agasfer [191]

Answer:

Approximately, 6.283..

Step-by-step explanation:

First calculate the area of the whole circle

We have radius(r)=4 cm

Area of circle(a)=pir^2

=pi×(4)^2

=pi×16

=Approximately,50.265......

A cirlce has a total of 360 degrees

Therefore,we can conclude 360 degrees=50.265...

or,1 degree=50.265/360

1 degree=Approximately,0.139

Now,

Area for the shaded region = Area of 45 degree

=0.139×45=Approximately,6.283.....

Therefore,the area of the shaded region is approximately,6.283....

Solve the equation by using the quadratic formula.<br> 3 x squared minus 1 = 7 x
Paladinen [302]

Answer:

b.  \frac{7+\sqrt{61} }{6} ,\frac{7-\sqrt{61} }{6}

Step-by-step explanation:

3x^{2} -1=7x

Quadratic equations are suppose to be written as: ax^2+bx+c=0

so the new quadratic equation for this problem will be: 3x^{2} -1-7x=0

Now rearrange the terms: 3x^{2} -7x-1=0

Then use the Quadratic Formula to Solve for the Quadratic Equation

Quadratic Formula = x=\frac{-b±}{} \frac{\sqrt{b^2-4ac} }{2a}

Note: Ignore the A in the quadratic formula

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

3x^{2} -7x-1=0

a = 3

b = -7

c = -1

x=-(-7)±\frac{\sqrt{(-7)^2-4(3)(-1)} }{2(3)}

Evaluate The Exponent

x=\frac{7±\sqrt{(49)-4(3)(-1)} }{2(3)}

Multiply The Numbers

x=\frac{7±\sqrt{49+12} }{2(3)}

Add The Numbers

x=\frac{7±\sqrt{61} }{2(3)}

Multiply The Numbers

x=\frac{7±\sqrt{61} }{6}

What is the equation of the line that is parallel to the given line and has an x-intercept of –3?
balandron [24]
The slope would be the same as that of the given line, and when plugging in (-3,0) into the new equation, you’ll find the y-intercept. If you could give the original given line equation I’d be happy to show you!
