Answer:

B:12

Step-by-step explanation:if you get a calculator and put the equation 16 + 4 - (5 x 2) + 2 you will get 12.

The value of the expression is 12.

The BODMAS rule states that an expression with more than one operators need to be solved from left to right in order of BODMAS, where B = Brackets, O = Orders, D = Division, M = Multiplication, A = Addition, S = Subtraction.

The given expression is 16+4-(5×2)+2

First we have to do multiplication in bracket,

= 16+4-10+2

= 20-10+2

= 10+2

= 12

The value = 12

Answer:

k=24

Step-by-step explanation:

The tangent of the function f at x=a, can be found by differentiating f w.r.t. x and then replacing x with a.

f=-x^2+8x+20

Differentiating both sides:

f'=(-x^2+8x+20)'

By sum rule:

f'=(-x^2)'+(8x)'+(20)'

By constant multiple rule:

f'=-(x^2)'+8(x)'+(20)'

By constant rule:

f'=-(x^2)+8(x)'+0

By power rule:

f'=-2x+8

f' at x=a is -2a+8

This is the slope of any tangent line to the curve f.

The slope of g is 4 if you compare it to slope intercept form y=mx+b.

So we gave -2a+8=4.

Subtracr 8 on both sides: -2a=-4

Divide both sides by -2: a=2

The tangent line to the curve at x=2 is y=4x+k.

To tind y we must first know the y-coordinate of the point of tangency.

If x=2, then

f(2)=-(2)^2+8(2)+20=-4+16+20=12+20=32

So the point is (2,32).

g(x)=4x+k and we know g(2)=32.

This gives us:

32=4(2)+k

32=8+k

k=32-8

k=24

From the tangent given, the value of k will be 24.

From the information given, g(x) = 4x + k and this is a tangent to f(x)= -x² +8x + 20.

f(x)= -x² +8x + 20

= f'(x)  = -2x  + 8

The slope of tangent = -2x + 8  at (x , y)

g(x) = 4x  + k  

Hence, slope = 4

-2x + 8 = 4

Collect like terms

-2x = 4 - 8

-2x = - 4

Divide both side by -2

-2x/-2 = -4/-2

x = 2

f(x)= -x² +8x +20

where, x = 2

y = -2² + 8(2) + 20  

y =  32

Hence (2 , 32) lies on g(x)= 4x+k

32 = 4(2) + k

32 = 8 + k

k = 32 - 8

k = 24

In conclusion, the value of k is 24.

Answer:

21 because 7 x 3 is 21

Step-by-step explanation:

Answer:

(x - 24)(x + 3)

Step-by-step explanation:

Given

x² - 21x - 72

Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 21)

The factors are - 24 and + 3, since

- 24 × + 3 = - 72 and - 24 + 3 = - 21 , then

x² - 21x - 72 = (x - 24)(x + 3) ← in factored form

Answer:

There are 16 integers between -3.92 and 12.4

Step-by-step explanation:

If we want to find the integers between two numbers we just need to subtract the integer numbers of the interval.

The integer interval will be:

[tex][-3,12][/tex]

Now, we subtract them:

[tex]12-(-3)=12+3=15[/tex]

Let's recall that 0 is an integer

Therefore, the answer will be 16.

Answer:

Hence, both Marlon and Adrian both have the same at bats percentage.

Step-by-step explanation:

Marlon's at bats :

Number of at bats = 15

Hits = 6

Hit percentage = 6/15 * 100% = 40%

Adrian :

Number of at bats = 10

Hits = 4

Hit percentage = 4/10 * 100% = 40%

Hence, both Marlon and Adrian both have the same at bats percentage.

Answer:

y = 1/3x + 3

Step-by-step explanation:

Points on the graph: (0, 3) and (3, 4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4-3)/(3-0)

m= 1/3

Point-slope intercept:

y - y1 = m(x - x1)

y - 3 = 1/3(x - 0)

y - 3 = 1/3x

y = 1/3x + 3
