In the figure below, m

The expression of Mia's height in cm is 5 + x

The given parameters are

Mia's height = 5 cm taller than her sister

Her sister's height  = x

The parameter "Mia's height = 5 cm taller than her sister" means that

Mia's height = 5 cm + her sister's height

Substitute Her sister's height  = x in Mia's height = 5 cm + her sister's height

Mia's height = 5 cm + x

This means that the expression of Mia's height in cm is 5 + x

Answer:

Step-by-step explanation:

speed = distance/time

however speed is a compound measure

distance to school = speed x time

                               = 30mph x 1/3hr

                               = 10m

time =  10m / 45mph

       = 13.3 (recurring)

Answer:

m∠a = 100°

m∠b = 100°

m∠c = 110°

Step-by-step explanation:

Calculation of m∠a

∠a is an exterior angle of ΔPST .
Therefore m∠a  = sum of the interior angles of ΔPST
m∠a = 30 + 70 = 100°

Calculation of m∠c

∠c and ∠PST are supplementary so their measures must add up to 180°
m∠c + 70° = 180° so m∠c = 180 - 70 = 110°

Calculation of m∠b
QRST is a quadrilateral.
The sum of the interior angles of the quadrilateral = 360°
So m∠a + m∠b + 50 + m∠c = 360°
We have already computed ∠a = 100° and ∠c = 110°
So 100 + m∠b + 50 + 110 = 360°
260 + m∠b = 360
m∠b = 360 - 260 = 100°

Answer:

it's -2/67x12w<3(xyz)

The critical number of the given function {g(t) = 3t ㏑t} is t = e⁻¹

Assume f(x) is a function with an open interval (a,b). If c is in the interval (a,b) and either f'(c) =0 or f'(c) does not exist, we say c is a critical number of f(x).

Each local minimum as well as maximum of f(x) must correspond to a critical number of f(x). The opposite is not truly the case: not all critical number of f(x) must correspond to a local maximum as well as minimum of f(x).

Now, as per the question;

It should be noted that the broadest possible domain of {g(t) = 3t ㏑t} is given in the set {t : t > 0} as ㏑t can not be defined for negative numbers of zero.

Now, differentiate the given function with respect to t.

[tex]g^{\prime}(t)=\frac{d}{d t}(3 t \ln t)[/tex]

Apply the product rule of differentiation;

[tex]\begin{aligned}&=\left[\frac{d}{d t}(3 t)\right] \ln t+3 t \frac{d}{d t}(\ln t) \\&=3 \ln t+3 t \frac{1}{t} \\&=3 \ln t+3 \\&=3(\ln t+1)\end{aligned}[/tex]

Now, put this value of g'(t) = 0 for finding the critical points.

0 = g'(t)

  = 3(㏑t + 1)

Divide equation by 3.

0 = ㏑t + 1

㏑t = -1

Taking anti log;

t = e⁻¹ (critical value)

Therefore, the critical value obtained for the given function is  t = e⁻¹.

The complete question is-

how many critical numbers does {g(t) = 3t ㏑t} have? note: critical numbers must be within the domain of the function.

Answer:

1a. -( x + 1)² + 4

1b. y-intercept at y = 3

1c. x-intercepts at x = -3 and x = 1

Derivation of 1b and 1c below

Step-by-step explanation:

Question 1a

The vertex equation form of a parabola is given by

y = a(x-h)²  + k where (h, k) are the coordinates of the vertex

If a > 0 then the parabola is facing up(vertex is at a minimum)  and if a < 0 then parabola is facing down (vertex at a maximum)

From the graph we see that the parabola is facing down so a = -1

The vertex is at (-1, 4) so h = -1 and k = 4

Therefore the equation of the parabola is

y = -1(x - h)² + k = -1(x- (-1))² + 4 = -1(x + 1)² + 4

y = -( x + 1)² + 4   (Answer 1a)

Question 1b

The y-intercept is the y-value where the parabola crosses the y-axis. From the graph we see that the parabola crosses the y-axis at y = 3 and x = 0

So y-intercept from the graph is 3

To solve algebraically, set x = 0 in the parabola equation and solve for y

We get, for x = 0,

y = - (0 + 1)² + 4

y = -(1²) + 4 = -1 + 4 = 3

Hence verified

Question 1c

There will be two x-intercepts for a parabola. Looking at the graph we see that the parabola intersects the x-axis at two points (-3, 0) and (1, 0). So the two x-intercepts are -3 and 1

Algebraically we can determine the x-intercepts by setting y = 0 and solving for the two values of x

Setting y = 0 in the parabolic equation, we get
y = 0 = -(x + 1)² + 4

Switch sides
-(x + 1)² + 4 = 0

-(x + 1)² = -(x² + 2x + 1) = -x² -2x - 1

-(x + 1)² + 4 = 0
==> -x² -2x - 1 + 4 = 0

==> -x² - 2x +3 = 0

Multiply by -1 both sides
==> x² + 2x - 3 = 0

Solve this quadratic equation by factoring

x² + 2x - 3 = (x - 1)(x + 3) = 0

The solutions are
x - 1 = 0   ==> x = 1

x + 3 = 0 ==> x = -3

Hence verified

Answer:

Exact Form:

51/2

Decimal Form:

25.5

Mixed Number Form:

25 1/2

Step-by-step explanation:

the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.

When we write in interval notation, the parenthesis are used to denote that the "ends" of the interval don't belong to the interval.

This means that in (a, b).

a and b don't belong to that interval.

While if instead we wrote [a, b]

In that case, a and b belong.

For the case of the exponential function:

y = a^x

As x tends to really large negative values, the value of y will tend to zero asymptotically. This means that y is really close to zero, but it is never equal to zero.

Then the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.

The cost for 14 cranberry juice bottles would be $7.56

In this question, Sophia buys 13 bottles of cranberry juice at the corner store for a total cost of $7.02

If each bottle costs the same amount, we need to find the amount for 14 bottles of juice.

Let x be the cost of one bottle of cranberry juice.

13 bottles of cranberry juice costs $7.02

So, we get an equation,

13x = $7.02

We solve above equation to find the cost of 1 bottle of cranberry juice.

x = $0.54

Answer: 22

Step-by-step explanation:

this problem is solved by a system of equations

Let Arthur’s current age be represented by:a

His brother’s current age will be represented by: b

The first equation will be:

a = 7 + b

The second equation will be:

a + 8 = 2b

now we solve for the equations. Plug in a = 7+b into a in the second equation.
So now we have

b+7+8=2b

Simplify:

B+15=2b

15=b

Arthur’s brother is 15 years old but since he is 7 years older we need to add 7 to 15

Hence, Arthur is 22 years old.

The rope's diameter is 10⁻³ inches greater than that of the floss, for example.

The diameter of a stand of rope is 1.2 × 10⁻³ inch.

The diameter of a strand of floss is 2 × 10⁻⁴ inches.

Subtract the diameter of the floss strand from the diameter of the rope to determine how much longer the diameter of the rope is than the diameter of the floss.

Therefore, the length by which the diameter of the strand of rope is longer than the diameter of the strand of floss will be:

= 1.2 × 10⁻³ inch - 2 × 10⁻⁴ inches

Now,

= 12 × 10⁻⁴ inch - 2 × 10⁻⁴ inch

= 10 × 10⁻⁴ inch

= 10⁻³ inch
