Answer:

x = 1.5 $\sqrt{14}$

Step-by-step explanation:

since the triangle is right we can use the trig. ratio sine to solve

sin 45° = $\frac{opposite}{hypotenuse}$ = $\frac{1.5\sqrt{7} }{x}$

multiply both sides by x

x sin45° = 1.5 $\sqrt{7}$

using sin45° = $\frac{1}{\sqrt{2} }$ , then

x × $\frac{1}{\sqrt{2} }$ = 1.5 $\sqrt{7}$

multiply both sides by $\sqrt{2}$

x = 1.5 $\sqrt{7}$ × $\sqrt{2}$ = 1.5 $\sqrt{14}$

Sav [38]

Let there exists a point (x, y) on the given line.

Slope of all points must be same, as they lie on the same line.

=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)

=> (y - 1)/(x - 2) = - 1/2

=> y - 1 = (-½) (x - 2)

Option 1 is the correct option

find x if the distance between points L and M is 15 and point M is located in the first quadrant. L=(-6,2) M=(x,2)

aivan3 [116]

Answer:

Therefore,

$x = 9$

Step-by-step explanation:

Given:

Let,

point L( x₁ , y₁) ≡ ( -6 , 2)

point M( x₂ , y₂ )≡ (x , 2)

l(AB) = 15 units (distance between points L and M)

To Find:

x = ?

Solution:

Distance formula between Two points is given as

$l(LM)^{2} = (x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}$

Substituting the values we get

$15^{2}=(x--6)^{2}+(2-2)^{2}\\\\225=(x+6)^{2}$

Square Rooting we get

$(x+6)=\pm \sqrt{225}=\pm 15\\\\x+6 = 15\ or\ x+6 = -15\\\\x= 9\ or\ x = -21$

As point M is located in the first quadrant

x coordinate and y coordinate are positive

So x = -21 DISCARDED

Hence,

$x = 9$

Therefore,

$x = 9$

Answer:

The distance travelled is 7.98×10³ miles.

Step-by-step explanation:

Given that the formula to find distance is Distance = Speed×Time. Then you have substitute the values into the formula :

$distance = speed \times time$

Let speed = 5.7×10²,

Let time = 1.4×10¹,

$d = (5.7 \times {10}^{2} ) \times (1.4 \times 10)$

$d = (5.7 \times 1.4) \times ( {10}^{2} \times 10)$

$d = 7.98 \times {10}^{3} miles$
