\log_7(x^2+4x-11)=\dfrac52

7^{\log_7(x^2+4x-11)}=7^{\frac52}

x^2+4x-11=7^{\frac52}

x^2+4x-\left(11+7^{\frac52}\right)=0

Now you can use the quadratic formula to solve for x.

x=-2\pm\sqrt{15+7^{\frac52}}

Your house is located at point T. Your grandma's house is located at point V. U is the midpoint of segment TV. How far do you ne
Vladimir [108]

Answer:

70

Step-by-step explanation:

From the question given above, the following data were obtained:

TU = 8x + 11

UV = 12x – 1

Next, we shall determine the value of x.

From the question:

U is the midpoint. This means that TU and UV are equal i.e

TU = UV

With the above idea in mind, we shall determine the value of x as follow:

TU = UV

TU = 8x + 11

UV = 12x – 1

8x + 11 = 12x – 1

Collect like terms

11 + 1 = 12x – 8x

12 = 4x

Divide both side by the coefficient of x i.e 4

x = 12/4

x = 3

Next, we shall determine the length of TU and UV. This can be obtained as follow:

TU = 8x + 11

x = 3

TU = 8(3) + 11

TU = 24 + 11

TU = 35

UV = 12x – 1

x = 3

UV = 12(3) – 1

UV = 36 – 1

UV = 35

Finally we shall determine the length of TV. This can be obtained as follow:

TV = TU + UV

TU = 35

UV = 35

TV = 35 + 35

TV = 70

Therefore, the distance between my house and grandma's house is 70.

NOTE: Assume the distance is measured in kilometer (km)

This means that I will travel 70 km from grandma's house to my house.

Volgvan

Answer:

d(apart are the ships)=42.8 meters

Step-by-step explanation:

Given data

h (height)=38m

Ф₁=53°

Ф₂=28°

d(how far apart are the ships)=?

Solution

d₅₃°(distance to ship at 53°)=h/tanФ₁

d₅₃°=38/tan(53°)

d₅₃°=28.6m

now

d₂₈°(distance to ship at 28°)=h/tanФ₂

d₂₈°=38/tan(28°)

d₂₈°=71.4m

d(apart are the ships)=d₂₈°-d₅₃°

d(apart are the ships)=71.4-28.6

d(apart are the ships)=42.8 meters
