Marianna [84]3 years ago
8 0

Answer:

The correct answer is d, there are infinitely many solutions.

Step-by-step explanation:

If the variable terms are the same and the constants are the same, the equation has infinitely many solutions.

Ex: 5(3)+5(5)=40                   3+5=8

     5(4)+5(4)=40                   4+4=8

Hope this helps! Brainliest please!

1) The solution for m² - 5m - 14 = 0 are x=7 and x=-2.

2)The solution for b² - 4b + 4 = 0 is x=2.

<u>Step-by-step explanation</u>:

The general form of quadratic equation is ax²+bx+c = 0

where

  • a is the coefficient of x².
  • b is the coefficient of x.
  • c is the constant term.

<u>To find the roots :</u>

  • Sum of the roots = b
  • Product of the roots = c

1) The given quadratic equation is m² - 5m - 14 = 0.

From the above equation, it can be determined that b = -5 and c = -14

The roots are -7 and 2.

  • Sum of the roots = -7+2 = -5
  • Product of the roots = -7\times2 = -14

The solution is given by (x-7) (x+2) = 0.

Therefore, the solutions are x=7 and x= -2.

2) The given quadratic equation is b² - 4b + 4 = 0.

From the above equation, it can be determined that b = -4 and c = 4

The roots are -2 and -2.

  • Sum of the roots = -2-2 = -4
  • Product of the roots = -2\times-2 = 4

The solution is given by (x-2) (x-2) = 0.

Therefore, the solution is x=2.

Given you or a person holding a kite string 100 feet long write and draw what the height or altitude the kite is off the ground
Salsk061 [2.6K]

Answer: 75.47\ ft

Step-by-step explanation:

Given

String of the kite is l=100\ ft

Angle of elevation \theta=49^{\circ}

suppose altitude of the kite is h

from the figure, we can write

\Rightarrow \sin 49^{\circ}=\dfrac{h}{100}\\\\\Rightarrow h=100\sin 49^{\circ}\\\\\Rightarrow h=75.47\ ft

Thus, the altitude of the kite is 75.47\ ft

Which of the following has a specific definition in geometry?
finlep [7]

Answer:

a line

Step-by-step explanation:

In geometry, we can define a line as a straight one- dimensional figure without thickness but extends infinitely in both directions.

If we are to put it into more understandable words, we can describe a line as the shortest distance between any two points.

A line has a specific definition in geometry. Every other option listed do not have specific definition in geometry.
