That would be evaluated to 31+1 because you have to keep change flip. Keep the 31, change the symbol to addition, then flip the negative 1 to a positive number.

Answer:

The fraction 7/8 is really close to 1 , so Yvonne could estimate that she needs approximately 6 yards of fabric per dress. So, to make 5 dresses, she would need approximately 30 yards.

Step-by-step explanation:

I'm not entirely sure, but 7/8 is very close to a whole, so this is what I would assume.

Aliens have injected Ana with mathematical nanobots. These nanobots force Ana to think about math more and more. Initially, ther
natulia [17]

Answer:

<em>Math will take over Ana's brain at 4.4 hours</em>

Step-by-step explanation:

<u>Exponential Grow </u>

The population of the nanobots follows the equation  

p(t) = 5\cdot 2^t

We must find the value of t such that the population of nanobots is 106 or more, that is

5\cdot 2^t\geq 106

We'll solve the equation

5\cdot2^t= 106

Dividing by 5

2^t= 106/5=21.2

Taking logarithms

log(2^t)= log(21.2)

By logarithms property

t\cdot log(2)= log(21.2)

Solving for t

\displaystyle t=\frac{log21.2} {log2}

t=4.4 \ hours

Math will take over Ana's brain at 4.4 hours

Need help with this math problem
blsea [12.9K]

Answer:

x=16

 Lenght of the equal sides: 71\ units

Step-by-step explanation:

You can observe in the picture that the triangle have two angles that have equal measure; therefore, it is an Isosceles triangle.

By definition, Isosceles triangles have two equal angles and two equal sides.

Based on this, you can write the following equation:

9x-73=3x+23

Solving for "x", you get this value:

9x-3x=23+73\\\\6x=96\\\\x=\frac{96}{6}\\\\x=16

Finally, you can subsitute the value of "x" into any expression to find the lenght of the equal sides:

3(16)+23=71\ units

Graph a parabola whose x-intercepts are at x = -3 and x = 5 and whose minimum value is y = -4.
shtirl [24]

Answer:

(See explanation and attachment below for further details)

Step-by-step explanation:

The parabola must satisfy the following conditions:

y + 4 = C\cdot (x - k)^{2}

y + 4 = C\cdot (x^{2}-2\cdot k \cdot x + k^{2})

The expression for the x-intercepts are, respectively:

x = -3

4 = C\cdot [(-3)^{2} - 2\cdot k\cdot (-3)+k^{2}]

\frac{4}{C} = 9 + 6\cdot k + k^{2}

x = 5

4 = C\cdot [5^{2}-2\cdot k \cdot (5)+k^{2}]

\frac{4}{C} = 25 - 10\cdot k + k^{2}

By equalizing both expressions:

9 + 6\cdot k + k^{2} = 25 - 10\cdot k + k^{2}

16\cdot k = 16

k = 1

And,

C = \frac{4}{25-10\cdot (1)+1^{2}}

C = \frac{1}{4}

The equation of parabola is:

y = \frac{1}{4}\cdot (x-1)^{2} - 4

Whose graph is included as attachment.
