Answer:

Step-by-step explanation:

(a) when there is a negative in front of the leading coefficient  (- x^2), that is a reflection over the x axis.  a regular parabola opens up.  In this case, the negative in front of the first term makes it open downward.  

-f(x) is a reflection    so -2x^2 would open downward.

(b) the vertex of the parabola is -b/2a

in this problem a x^2 + bx + c = y

                         -2x^2 + 4x + 3 = y

a = -2, b = 4, c = 3

formula for vertex -b/2a  = -4/2(-2)    = -4/-4  = 1    This is the x-value of the vertex.  Plug back into original equation to find the y value.

(1, ?)    -2(1)^2 + 4(1) + 3 = 5

vertex is (1,5) and is above the x axis

Answer:

B

Step-by-step explanation:

We can use the logarithm property shown below to evaluate this:

[tex]Log(x*y*z)=logx+logy+logz[/tex]

Now we can write Log 12 as Log (2*2*3).

Using the rule, we can write:

Log (2*2*3) = Log 2 + Log 2 + Log 3

We are given values of Log 2 and Log 3, plugging these we get:

Log (2*2*3) = Log 2 + Log 2 + Log 3

Log (2*2*3) = 0.3010 + 0.3010 + 0.4771 = 1.0791

Answer choice B is right.

We can factor out 12 using 2 and 3.

log(12) = log(2^2 * 3)

Rewrite it using the product rule [ log(xy) = log(x) + log(y) ]

log(2^2 * 3) = 2 log(2) + log(3)

Simplify using the given values.

2(0.3010) + 0.4771

0.602 + 0.4771

1.0791

Therefore, the answer is b. ≈ 1.0791

Answer:

16.51

Step-by-step explanation:

In a parallelogram, the opposite angles are always equal in measure. So two of the angles in the parallelogram measure 39 degrees each.

The sum of angles of the parallelogram must be 360 degrees. Let the other two angles be x degree each. We can set up the following equation for the angles:

39 + 39 + x + x = 360

78 + 2x = 360

2x = 282

x = 141

This means, the other two angles measure 141 degree each. The shorter diagonal will be opposite to the shorter angle.

Hence, the diagonal opposite to the angle 39 degree will be the shorter one. A diagonal divides the parallelogram in two triangles. So we will have two sides and an included angle and we have to find the third side of the triangle which can be found using the law of cosines. Let the third side be c as shown in image below, using the law of cosines, we can write:

[tex]c^{2} = a^{2}+ b^{2} -2ab cos(\gamma)\\\\c^{2}=18^{2}+26^{2}-2(18)(26)cos(39)\\\\ c^{2}=272.59\\\\ c=16.51[/tex]

Thus the shorter diagonal will be 16.51 feet in measure.

To find the shorter diagonal of a parallelogram with given side lengths and angle, use the formula √(a^2 + b^2 - 2abcosθ).

To find the shorter diagonal of a parallelogram, we need to use the formula:

Shorter diagonal = √(a^2 + b^2 - 2abcosθ)

Where a and b are the sides of the parallelogram and θ is the angle between them.

Using the given information, we have a = 18 ft, b = 26 ft, and θ = 39°.

Substituting these values into the formula, we get:

Shorter diagonal = √(18^2 + 26^2 - 2(18)(26)cos(39°))

Calculating this expression gives us:

Shorter diagonal ≈ 9.15 ft

Answer:

[tex]\$103.75[/tex]

Step-by-step explanation:

step 1

Find the area of the gate

The area of the gate is equal to the area of a trapezoid minus the area of the rectangular glass panel

[tex]A=\frac{1}{2}(10+7)(5)-(0.71)(1.43)= 41.5\ ft^{2}[/tex]

step 2

Find the cost

Multiply the total area by $2.50  

so

[tex]41.5*2.50=\$103.75[/tex]

Answer: Third option.

Step-by-step explanation:

Calculate the area of the gate (including the glass panel) which has the shape of a trapezoid.

The formula for calculate the area of a trapezoid is:

[tex]A=\frac{h}{2}(B+b)[/tex]

Where h is the height, B is the larger base and b is the smaller base.

In this case:

[tex]B=10ft\\b=7ft\\h=5ft[/tex]

Substituting, you get:

[tex]A_{gate}=\frac{5ft}{2}(10ft+7ft)=42.5ft^2[/tex]

Calculate the area of the rectangular glass panel, with the formula:

[tex]A_{panel}=l*w[/tex]

Where the lenght is [tex]l=1.43ft[/tex] and the width is [tex]w=0.71ft[/tex]

Then:

[tex]A_{panel}=(1.43ft)(0.71ft)=1.01ft^2[/tex]

The area he needs to paint is:

[tex]A=A_{gate}-A_{panel}\\A=42.5ft^2-1.01ft^2\\A=41.49ft^2[/tex]

If painting the gate costs $2.50 per ft², for 41.49 ft² he will have to spend:

[tex]=(41.49)(\$2.50)\\=\$103.725[/tex]

Therefore the answer is the third option.

To calculate the cost of painting the gate, find the area of the glass panel by multiplying its length and width. Multiply the area by the cost per square foot to find the total cost.

To calculate the cost of painting the gate, we need to find the area of the glass panel first. Let's say the length of the panel is 'l' feet and the width is 'w' feet. The area of a rectangle is given by the formula A = l × w. Once we have the area, we can multiply it by the cost per square foot ($2.50) to find the total cost. So the formula to calculate the cost of painting the gate is: Cost = Area × Cost per square foot. Substitute the values you know into the formula and solve for the cost.

Since, when we solve the given expression the steps of solution are as follows,

Step 1 : 7b + 3.2b - 5 = 18.92

Step 2 : 10.2b - 5 = 18.92      ( Combining like terms in left side )

Step 3 : 10.2b = 23.92           ( Adding 5 on both sides )

Answer:

the answer is 119g

Step-by-step explanation:

x-120/4.3=-0.25

x-120=-1075

x=118.925=119g

Approximately 40% of the tomatoes weigh less than 119 g.

The correct answer is option D.

A z-score also called a standard score is a measure of how many standard deviations a data point is away from the given mean of a distribution.

It measures the unusual or extreme a particular data point is compared to the rest of the distribution

We have,

To solve this problem, we can use the cumulative distribution function (CDF) of the normal distribution.

The CDF gives the probability that a random variable is less than or equal to a given value.

Given that the mean of tomato weight is 120 grams and the standard deviation is 4.3 grams,

We can use this information to find the probability that a randomly selected tomato weighs less than a certain amount.

Let's calculate the z-score for each option:

A. 111 g:

z-score = (111 - 120) / 4.3 ≈ -2.093

B. 114 g:

z-score = (114 - 120) / 4.3 ≈ -1.395

C. 117 g:

z-score = (117 - 120) / 4.3 ≈ -0.698

D. 119 g:

z-score = (119 - 120) / 4.3 ≈ -0.233

Now, we can use a standard normal distribution table or a calculator that provides the cumulative distribution function (CDF) of the standard normal distribution to find the probability corresponding to each z-score.

The option with the highest probability, or approximately 40%, is the correct answer.

Based on the calculations, it appears that option D. 119 g has the highest probability of approximately 40% for a tomato weighing less than that amount.

Thus,

Approximately 40% of the tomatoes weigh less than 119 g.

Step-by-step explanation:

Points Rosh received for becoming a member = 15

Points Rosh received for visiting the moving theater = 3.5

Total points needed for a free movie ticket = 55

For each visit he receives 3.5 points, so for x visits he will receive 3.5x points.

Total points = Points received on becoming a member + Points received on x visits

So,

Total Points = 15 + 3.5x

These points must be at least 55 for a free movie ticket. At least means equal to or greater than. So the total points must be equal to or greater than 55 in order to earn a free movie ticket. This can be expressed as:

1 red pair of pants

the total number of garments is: 2 + 1 + 1 + 1 + 1 + 1 = 7

the number of blue ones is: 2 + 1 + 1 = 4

the number of belts is: 1

then, the probability of selecting at random one blue garment is equal to the number of blue ones divided the total number:

Pa = 4/7 =0.57

the probability of selecting the belt is equal to the number of belts divided the total number of garments, this is:

Pb = 1/7 = 0.14
