F (x) = -4x² + 10x + 13
Alexus [3.1K]

Answer:

f(7) = -113

Step-by-step explanation:

Hello!

Substitute 7 for x in the equation.

<h3>Evaluate</h3>
  • f(x) = -4x² + 10x + 13
  • f(7) = -4(7)² + 10(7) + 13
  • f(7) = -4(49) + 70 + 13
  • f(7) = -196 + 70 + 13
  • f(7) = -113

f(7) is -113.

A bag contains 150 marbles. Some are blue, and the rest are white. There are 21 blue marbles for every 4 white marbles. How many
Olin [163]

Given:

Total number of marbles in the bag = 150

There are 21 blue marbles for every 4 white marbles.

To find:

The number of blue marbles in the bag.

Solution:

Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.

Let the number of blue marbles be 21x and white marbles be 4x.

Total number of marbles in the bag = 150

21x+4x=150

25x=150

Divide both sides by 25.

x=\dfrac{150}{25}

x=6

Now,

\text{Blue marbles}=21x

\text{Blue marbles}=21(6)

\text{Blue marbles}=126

Therefore, the number of blue marbles is 126.

How many solutions does the equation sin(4x)= 3/4?
MAVERICK [17]
sin(4x)=  \dfrac{3}{4} 

4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4}) 

<span>Since sin is a periodic function, add the periodicity. 
</span>
4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ &#10;&#10; 

4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4},  nEZ 

x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ
