Answer:

Average rate of change = [tex]\frac{15}{2}[/tex]

Step-by-step explanation:

For a closed interval [tex][a,b][/tex] in a function, the average rate of change is [tex]m=\frac{f(b)-f(a)}{b-a}[/tex].

Thus, given our interval of [tex][1,2][/tex] from the directions, we determine that [tex]f(b)=f(2)=-\frac{10}{(2)^2}=-\frac{10}{4}=-\frac{5}{2}[/tex] and [tex]f(a)=f(1)=-\frac{10}{(1)^2}=-\frac{10}{1}=-10[/tex].

Hence, [tex]m=\frac{f(b)-f(a)}{b-a}=\frac{(-\frac{5}{2})-(-10) }{2-1}=\frac{\frac{15}{2}}{1}=\frac{15}{2}[/tex].

In conclusion, the average rate of change of the function from x=1 to x=2 is [tex]\frac{15}{2}[/tex].

Step-by-step explanation:

Answer:

x-intercepts: (1,0), (−2,0) and (2,0)

y-intercept: (0,4)

The graph is rising and crosses 3 times the x-axis and 1 time the y-axis as shown above.

Step-by-step explanation:

★First let's find out the sum.

(9x + 2y - 3z) + (-10x + y - z) + (2x + 3y + 7z)

= (9x - 10x + 2x) + (2y + y + 3y) + (-3z - z + 7z)

= (x) + (6y) + (3z)

= x + 6y + 3z

★Now subtraction:

(x + 6y + 3z) - (4x - 5y + 3z)

= (x + 6y + 3z - 4x + 5y - 3z)

= (x - 4x + 6y + 5y + 3z - 3z)

★∴Answer is -3x + 11y

Answer:

m∠A=88°

Step-by-step explanation:

∠ABC=∠ACB=46° (base angles of isos triangle)

           ∠BAC=180°-46°-46° (angle sum of triangle)

                     =88°

= (1/2 × 6 × 4) square units

= (3 × 4) square units

= 12 square units

The area of the triangle is 12 square units.

Hope it helps.

Do comment if you have any query.

=================================================

First, Identify what is the height and base of the triangle.

[tex] \rightarrow [/tex] Height = 4 units

[tex] \rightarrow [/tex] Base = 6 units

[tex] \\ [/tex]

Now to find the area of the triangle, use the formula:

[tex] \rightarrow [/tex] Area = [tex] \sf \frac{Height × Base }{2} [/tex]

Solve.

[tex] \rightarrow [/tex] = [tex] \sf \frac{4 × 6}{2} [/tex]

[tex] \rightarrow [/tex]= [tex] \sf \frac{24 }{2} [/tex]

[tex] \rightarrow [/tex] = 12

Therefore, the area of the triangle is 12 units.

Answer:

B) A = 52.3°, b = 1.7 m, c = 2.8 m

Step-by-step explanation:

We know that it is a right angle triangle because C = 90°

because of that we can do 180 - 90 + 37.7

which is a=52.3

Because it is a right angle triangle, we can use sin, cos,tan

I will use sin to find the side of c

2.2 is a

sin 52.3 = 2.2/x

x= 2.2/ sin 52.3

x=2.78

You could do cos or tan but the pythagorean theorem for me is much faster

so it looks like this, a^2+b^2 =c^2

in this case we have both a and c we want b

so we rearrange

c^2-a^2=b^2

2.78^2-2.2^2= b^2

[tex]\sqrt{2.89}[/tex]=b

1.7=b

therefore it would be this option B) A = 52.3°, b = 1.7 m, c = 2.8 m

[tex] \frac{28}{3} [/tex]

Step-by-step explanation:

number 1 equals 8 1/5

number 2 equals 5

number 3 equals 9 1/3

Answer:

f( 1 ) = 3

Step-by-step explanation:

Given the linear function, f(x) = -4x + 7, we could easily find f( 1 ) by substituting the value of the input, x = 1, into the function.

f(x) = -4x + 7

f( 1 ) = -4( 1 ) + 7

f( 1 ) = -4 + 7

f( 1 ) = 3

Therefore, the output value is f( 1 ) = 3.

The standard form of the function is [tex]4x^2+48x + 149[/tex]

The standard quadratic equation is expressed as:

Given the vertex form of an equation expressed as [tex]g(x) = 4(x + 6)^2 + 5[/tex]

Expand the expression:

[tex]f(x) = 4(x + 6)^2 + 5\\f(x) = 4(x^2+12x + 36) + 5\\f(x) = 4x^2+48x + 149\\[/tex]

Hence the standard form of the function is [tex]4x^2+48x + 149[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

If the angle of elevation at point B is 7.4°, then the sun is 90° -7.4° = 82.6° from the vertical. This is the measure of the central angle between the two points. That represents a fraction of a circle that is ...

  82.6°/360° = 413/1800 ≈ 0.229444...(repeating)

The relation between the given distance and the circumference is ...

  0.294444C = 2105 mi

  C = 2105 mi/0.294444 ≈ 9174 mi

The radius of the spherical planet is this divided by 2π:

  r = C/(2π) = 9174 mi/(2π) ≈ 1460 mi

The radius of the planet is about 1460 miles; the circumference is about 9174 miles.

Answer:

Option B is correct.

Answer:

Step-by-step explanation:

a) The height of the springboard above the water should be h(0) : Read, the height at t = 0

h(0) = -5(0) + 10(0) + 3

h(0) = 0 + 0 + 3

h(0) = 3

a) 3 meters

b)  The time it takes the diver to hit water should be, the positive 0 solution for t.  Remember, in a quadratic equation,  there are two values for t where a parabola crosses the horizontal axis, which in this case would be t.  Just by looking at the function, h(t) = -5t2 + 10t + 3 , one should be able to see that it cannot be factored easily, so it requires the Quadratic Formula to find the zeros ; x = -b ±√(b2-4ac)  / 2a

Substitute t for x, and use the coefficients for a, b, c:

t  =  (-10 ± √((102 - 4(-5)(3)))/2(-5)

t = (-10 ±√(100 + 60))/-10

t = (-10 ±√160)/-10) ; Now factor the 160 to simplify:

t = (-10 ±√(10*16))/-10

t = (-10 ±4√10)/-10 ; Factor out leading coefficient of -2 from the numerator:

t = -2(5 ± 2√10)/-10

t = (5 ± 2√10)/5

Using a calculator to find the zeros, and disregarding the negative zero (because t starts at 0):

t ≈ 2.265

b) approx. 2.265 seconds for diver to hit water.

c) To find this, set the function equal to 3 to find what other value for t would be equal to 3 (we know one is 0).

-5tt + 10t + 3 = 3

-5t2 + 10t = 0 ; factor out t

t(-5t + 10) = 0

We know t = 0:

We also know that -5t + 10 = 0

-5t = -10

t = 2

c) 2 seconds. This is the time that diver would equal height of t=0 which is where he started, and where he equals the height of the springboard.

d and e) The peak of the dive (parabola), is determined using the formula h = -b/2a (Derived from the Quadratic Formula) to find the y value (in this case, the h value, answering e) and then using that result in the function to find the x value (in this case, the t value answering d) of the point where the parabola (dive path) reaches a maximum(height), or minimum(in upward opening parabolas).

h = -10/2(-5)

h = -10/-10

h = 1

h(1) = -5(1)2 + 10(1) + 3

h(1) = -5 + 10 + 3

h(1) = 8

d) At t = 1 second, diver will have reached peak of dive.

e) At t = 1 second, diver will have reached a maximum height of 8 meters.
