Given that f(x) = x2 + 8x – 5 and b = f(4), what is the value of -b? (Use only the digits 0-9 and the negative sign if necessary to enter the value.)

Answers

Answer 1
Plug in 4 for x
f(4) = 4^2 + 8(4) - 5
f(4) = 16 + 32 - 5 = 43
B = 43, so -B = -43

Solution: -43

Work out
47% of £900

Answers

Answer:

47 percent *900 =

(47:100)*900 =

(47*900):100 =

42300:100 = 423

Now we have: 47 percent of 900 = 423

Question: What is 47 percent of 900?

Percentage solution with steps:

Step 1: Our output value is 900.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$900=100\%$.

Step 4: Similarly, $x=47\%$.

Step 5: This results in a pair of simple equations:

$900=100\%(1)$.

$x=47\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{900}{x}=\frac{100\%}{47\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{900}=\frac{47}{100}$

$\Rightarrow x=423$

Therefore, $47\%$ of $900$ is $423$

Answers

Answer:

θ = πk, 1.318+2πk, 4.965+2πk

Step-by-step explanation:

4sin(2θ) − 2sin(θ) = 0

8sin(θ)cos(θ) - 2sin(θ) = 0

2sin(θ)[4cos(θ)-1] = 0

2sin(θ) = 0

sin(θ) = 0

θ = πk

4cos(θ)-1 = 0

4cos(θ) = 1

cos(θ) = 1/4

θ ≈ 1.318+2πk, 4.965+2πk

Therefore, θ = πk, 1.318+2πk, 4.965+2πk

GEOMETRY HOMEWORK HELP! PLS!!

Answers

Answer:

x = 37°

Step-by-step explanation:

Given the triangle with two given exterior angles, m ∠107° and m ∠110°:

We can use the exterior angle theorem where it states that the measure of each exterior angle of a triangle is equal to the sum of the measures of the opposite and remote interior angles.

Start by finding the supplement of m ∠110°, that will serve as the other remote interior angle.

The supplement of ∠110° is:

∠110° + y  = 180°

Where y = represents the other unknown interior angle.

Subtract ∠110° from both sides:

∠110° - ∠110°  + y  = 180° - ∠110°

y =  70°

Therefore, the other remote interior angle is y = 70°. Now, we can determine the value of x by establishing the following equation:

107° = x° + 70°

Subtract 70 from both sides:

107° - 70° = x° + 70°- 70°

x = 37°

0.90 and 0.75

Then the division between the numbers 0.90 and 0.75 will be given by putting a division sign between them. Then we have

⇒ 0.90 ÷ 0.75

⇒ 0.90 / 0.75

⇒ 1.20

The worth of the mathematical articulation 0.90 ÷ 0.75 in the decimal structure will be 1.20.

y = 1.6x −5

Step-by-step explanation:

We start with two points, let’s say (0,-5) and (4,1.4).

The equation is:

y=mx+b

m is the slope and b the y-intercept.

We can find the slope by:

[tex]\frac{y_2-y_1}{x_2-x_1} = \frac{-5-1.4}{0-4} = 1.6[/tex]

Then solve the equation for b:

y = 1.6x + b ->

−5 = 1.6(0) + b ->

b = -5.

So the final equation is:

y = 1.6x −5.
