kompoz [17]

Answer:

his weekly exercise time goal in minutes = 200 minutes

Step-by-step explanation:

Jerry has reached 39% of his weekly exercise time goal.

so far this week ,he has exercise for a total of 78 minutes this week.

39% of total = 78 minutes

100%= x

X=100*78/39

X=100*2

X= 200 minutes

his weekly exercise time goal in minutes = 200 minutes

F(x) = x ^ 2 - 8x + 7
bekas [8.4K]
Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.

aleksley [76]

Well I don't know how to show work on this one.



50. 2 3/4 is between 2 and 3, three times farther from two than three. Draw a dot in approximately that locations and mark it 2 3/4.


51. 4 1/3 is between 4 and 5, twice as far from five as from four. Draw a dot and mark it 4 1/3.

Which expression is equivalent to StartRoot 200 EndRoot?
Verdich [7]

Answer:

b)  √200 = 10√2

Step-by-step explanation:

Here, the given expression is: √200

Simplifying the given expression, we get:

200 = 2 x 2 x 2 x 5  x 5

⇒ 200  = (2)²  x (5) ²  x 2

Taking ROOT both sides, we get:\sqrt{200}  = \sqrt{(2)^{2}  \times (5)^{2}  \times  2}\\\implies \sqrt{200} = \sqrt{(2)^{2} } \times \sqrt{(5)^{2} } \times  \sqrt{(2) }  = 2 \times 5 \times \sqrt{2}\\ = 10 \sqrt {2}\\\implies \sqrt{200}  =  10 \sqrt {2}

Hence,   √200 = 10√2
