What are the solutions to the equation 9x2 = 49, rounded to the nearest tenth?A.
2.3, –2.3

B.
5.4, –5.4

C.
7, –7

D.
21, –21

Answers

Answer 1
Answer: A.
2.3, –2.3

Working;

9x^(2) =49
x^(2) = (49)/(9)
x=\sqrt{ (49)/(9) }
x= +-2.3
Answer 2
Answer: I would go for A if anything

Assuming that g(x) = (1)/(3) f(x) \: and \: h(x) = - g(x) + 4
fill in the following table.​

Answers

The value of the functions g(-6) is 6, g(0) is 5, g(7) is 8, h(-6) is 2, h(0) is 9 and h(7) is 12.

x -6 0 7

f(x) -18 15 24

g(x) 6 5 8

h(x) 2 9 12

g(-6) = 6 because g(x) = 1/3 f(x) and f(-6) = -18.

g(0) = 5 because g(x) = 1/3 f(x) and f(0) = 15.

g(7) = 8 because g(x) = 1/3 f(x) and f(7) = 24.

h(-6) = 2 because h(x) = -g(x) + 4 and g(-6) = 6.

h(0) = 9 because h(x) = -g(x) + 4 and g(0) = 5.

h(7) = 12 because h(x) = -g(x) + 4 and g(7) = 8.

Please note that these are just the values of g(x) and h(x) at the specific points given in the table. To find the values of g(x) and h(x) for other values of x, you can use the given formulas.

#SPJ1

For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at x = 5. What is definitely true about x = 5?Both f(x) and g(x) cross the x-axis at 5.
Both f(x) and g(x) cross the y-axis at 5.
Both f(x) and g(x) have a maximum or minimum value at x = 5.
Both f(x) and g(x) have the same output value at x = 5.

Answers

The last statement is the valid one: both f(x) and g(x) have the same output value at x = 5.

f(x) at x = 5 is f(5), this is the output of the function f when x =5
g(x) at x = 5 is g(5), this is the output of the function g when x =5

Then the two output have the same value at x =5.

Answer:

D)  Both f(x) and g(x) have the same output value at x = 5.

Find the equation of the circle whose center and radius are given.center ( 5, 6), radius = 3

Answers

Answer:

(x-5)^2+(y-6)^2 =9

Step-by-step explanation:

The  equation of circle is given by:

(x-h)^2+(y-k)^2 = r^2

where,

(h, k) is the center

r is the radius of the circle.

As per the statement:

Given: center ( 5, 6), radius = 3 units

⇒(h, k) = (5, 6) and r = 3 units

Substitute these in [1] we have;

(x-5)^2+(y-6)^2 = 3^2

(x-5)^2+(y-6)^2 =9

Therefore, the equation of the circle is, (x-5)^2+(y-6)^2 =9

the general formula of the circle is (x-h)^2 + (y-k)^2 = r^2 
where (h,k) the center of the circle and r is the radius  
so , the equation is (x-5)^2 + (y-6)^2 = 9

A bicycle wheel has a radius of 28 cm. what is the circumference of the wheel?

Answers

Answer:

  176 cm

Step-by-step explanation:

You want the circumference of a wheel with a radius of 28 cm.

Circumference

The circumference of a circle is given by ...

  C = 2πr

For r = 28 cm, this is ...

  C = 2π(28 cm) = 56π cm ≈ 176 cm

The circumference of the wheel is 56π cm, about 176 cm.
