Assuming that no transversal line is present, I can present only the statements base on the figures of a parallelogram. A parallelogram is a <span>quadrilateral. They only differ on the number of their parallel sides. A square has 2 parallel sides and all of its sides are equal or the same. A rhombus has 2 parallel sides and all of its sides are equal or only two of its sides are equal. A rectangle has 2 parallel sides. One parallel side is the same and can be bigger or smaller than the other parallel side. Trapezoid has only one pair of parallel sides. The other pair is a mirror to the other. </span>

Robert makes $951 gross income per week and keeps $762 of it after tax withholding. How many allowances has Robert claimed? For
MAXImum [283]

Answer:

Option D,four is correct

Step-by-step explanation:

The tax withholding from the gross income of $951 is the gross income itself minus the income after tax withholding i.e $189  ($951-$762)

The percentage of the withholding =189/951=20% approximately

Going by the multiple  choices provided,option with 4,189 dollars seems to the correct option as that is the exact of the tax withholding on Robert's gross income and his earnings fall in between $950 and $960

alexgriva [62]

Answer:

0.0003W/cm°C

Step-by-step explanation:

The question is not properly written. Here is the correct question.

The batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c

Given the thermal conductivity in W/m°C to be 0.03W/m°C

We are to rewrite the value in W/cm°C

The difference is the unit. The only thing we need to do is to simply convert the unit (metres) in W/m°C to centimeters (cm)

Since 100cm = 1m, 0.03W/m°C can be expressed as shown below;

= 0.03W/m°C

= 0.03 × W/1m×°C

Note that 1m = 100cm, substituting this conversion into the expression, it will become;

= 0.03 × W/100cm × °C

= 0.03/100 × W/cm°C

= 0.0003W/cm°C

Hence the battling thermal conductivity in W/cm°C is 0.0003W/cm°C

You count customers going into the 5 pizza shops in your city. You get 56, 98, 43, 112, and 106. What is the median number of cu
denpristay [2]

Answer:The answer is 98

Step-by-step explanation:

Median is the middle number, so put the numbers from least to greatest and pick the number in the middle. In this case: 43,56,98,106,112. 98 is in the middle.

Which graph represents y=3 sqrt x+2
ziro4ka [17]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=3\sqrt{x+2}

Remember that the radicand must be greater than or equal to zero

so

x+2\geq 0

solve for x

subtract 2 both sides

x\geq -2

The domain is the interval [-2,∞)

All real number greater than or equal to -2

For x=-2

y=3\sqrt{-2+2}=0

so

The range is the interval [0,∞)

All real number greater than or equal to 0

Find the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

y=3\sqrt{0+2}

y=3\sqrt{2}

y=4.243

The y-intercept is the point (0,4.243)

therefore

The graph in the attached figure

The minimum of the graph of a quadratic function is located at (-1,2) . the point (2,20) is also shown on the parabola . which f
Gekata [30.6K]
The complete question in the attached figure

we know that
the equation of a parabola is
y=a(x-h)²+k
where
(h,k) is the vertex   --------> (h,k)--------> (-1,2)
so
y=a(x+1)²+2

point (2,20)
for x=2
y=20
20=a(2+1)²+2--------> 20=a*9+2--------> 9*a=18---------> a=2

the equation of a parabola is
y=a(x+1)²+2-------> y=2(x+1)²+2

therefore

the answer is the option
<span>C) f(x) = 2(x + 1)2 + 2</span>
