Consider the following equation.

[tex]5^{-x}[/tex]+7=2x+4

Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a starting point.

a. x=[tex]\frac{7}{4}[/tex]

b. x=[tex]\frac{27}{16}[/tex]

c. x=[tex]\frac{13}{8}[/tex]

d. x=[tex]\frac{25}{16}[/tex]

C

Step-by-step explanation:

I think

The solution to the equation above using three iterations of successive approximation is x = 25/16

What is an equation?

An equation is an expression that is represented by the equality or equal to sign i.e "="

The equation is given as:

[tex]5^{-x} + 7 =2x + 4[/tex]

Equate to 0

[tex]5^{-x} + 7 -2x - 4 = 0[/tex]

Express as a function

[tex]f(x) = 5^{-x} + 7 -2x - 4[/tex]

The equation has a solution when f(x) = 0.

From the graph, we have:

x = 1.5

So, we have:

[tex]f(1.5) = 5^{-1.5} + 7 -2*1.5 - 4[/tex]

Evaluate

f(1.5) = 0.089

Set x to 1.52 to determine a closer value of f(x) to 0.

[tex]f(1.52) = 5^{-1.52} + 7 -2*1.52 - 4[/tex]

Evaluate

f(1.52) = 0.047

Set x to 1.54 to determine a closer value of f(x) to 0.

[tex]f(1.54) = 5^{-1.54} + 7 -2*1.54 - 4[/tex]

Evaluate

f(1.54) = 0.004

Notice that 0.004 is closer to 0 than 0.047 and 0.089

From the list of options, the closest value to 1.54 is 25/16

Hence, the solution to the equation above using three iterations of successive approximation is x = 25/16

10) Calculate angle u, v and w
A
Y
с
88
68

Answers

Answer:

u = 24, v = 92, and w = 184

Step-by-step explanation:

According to circle theorem, we have;

∠ACD = ∠ABD = 88° by angle inscribed in a circle and also subtending the same chord

∠DOA = 2 × ∠ABD by angle subtended at the center = 2 × Angle subtended at the circumference

∴ ∠DOA = 2 × ∠ABD = 2 × 88° = 176°

w° + ∠DOA = 360  by the sum of angles at a point

∴ w° = 360° - ∠DOA = 360° - 176° = 184°

w° = 184°

w° = 2 × v° by angle subtended at the center = 2 × Angle subtended at the circumference

∴ v° = w°/2 = 184°/2 = 92°

v° = 92°

In triangle ΔCDY and ΔABY, we have;

∠ABD = ∠ABY by reflexive property

∠ACD = ∠ACY by reflexive property

∠ACD = ∠ABD = 88°

∴ ∠ABY = 88°

∠CYD = ∠AYB  by vertically opposite angles are equal

∴ ∠CYD = 68° = ∠AYB

u° + ∠ABY + ∠AYB = 180° by angle sum property

∴ u° = 180° - (∠ABY + ∠AYB)

u° = 180° - (88° + 68°) = 24°

u° = 24°.

find two numbers if their sum is 3/5 and their difference is 7 1/5

Answers

Answer:

A = 3 + 9/10

B = -(3 + 3/10)

Step-by-step explanation:

We have two numbers, A and B, such that:

A + B = 3/5

A - B = 7 + 1/5

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:

A = 3/5 - B

Now we can replace this in the other equation:

A - B = 7 + 1/5

(3/5 - B) - B = 7 + 1/5

3/5 - 2*B = 7 + 1/5

-2*B = 7 + 1/5 - 3/5

-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5

B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)

Now that we know the value of B, we can use the equation

A = 3/5 - B

To find the value of A:

A = 3/5 - ( -(3 + 3/10))

A = 3/5 + (3 + 3/10)  = 6/10 + 3 + 3/10 = 3 + 9/10

The numbers are:

A = 3 + 9/10

B = -(3 + 3/10)

You have a square piece of bread that is 5 inches long and 5 inches wide. It it h inches high. The crust of the bread if 50% of the total surface area of the bread. What is the height, h, of the bread?

Answers

Answer:

2.5 inches

Step-by-step explanation:

equation :

(4×5) × h = 50% × [(2×5×5)+(4×5)×h]

20×h = 0.5 × (50 +20h)

20h = 25+10h

20h-10h= 25

10h = 25

h = 25/10

= 2.5 inches
