Answer:
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)=-2[/tex]
Hence, option B) is true.
Step-by-step explanation:
Given
g(t) = t² - 2
h(t) = t + 4
To determine
[tex]\left(g\:\circ \:\:h\right)\left(-4\right)=?[/tex]
Using the formula
[tex]\left(g\:\circ \:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)[/tex]
In order to determine g(h(-4)), first we need to determine h(-4), so
substituting t = -4 in h(t) = t + 4
h(t) = t + 4
h(-4) = -4 + 4
h(-4) = 0
so we can write
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)=g\left(0\right)[/tex]
now, to determine g(0), substitute t = 0 in g(t) = t² - 2v
g(t) = t² - 2
g(0) = (0)² - 2
g(0) = 0 - 2
g(0) = -2
so, finally we get
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)=g\left(0\right)=-2[/tex]
Therefore,
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)=-2[/tex]
Hence, option B) is true.

An airplane is flying from knoxville to new york. The distance it travels in miles, d, is related to the time in seconds, t, by the equation: d=0.12t. How many miles is it flying per second?
Answers
Answer:
0.12 miles is it flying per second.
Step-by-step explanation:
The distance d is related to time t in seconds is given by the equation as follows :
d =0.12 t
We need to find how many miles is it flying per second.
[tex]\dfrac{d}{t}=0.12\\\\\dfrac{\text{miles}}{\text{second}}=0.12[/tex]
So, the speed of the airplane is 0.12 miles per second, Hence, 0.12 miles is it flying per second.

Step-by-step explanation:
1 day - 24 hours

A square was altered so that one side is increased by 9 inches in the other side is decreased by 2 inches. The area of the resulting rectangle is 6o in 2 what was the area of the
Answers
Answer:
area of the original square = 36 in²
Step-by-step explanation:
given data
one side is increased = 9 inches
other side is decreased = 2 inches
area of the resulting rectangle = 60 in²
solution
we consider here x as the length of any one side
and
longer side of the resulting rectangle = x + 9
and
the shorter side x - 2
so that area of this rectangle is (s+9) × (s-2) = 60 in²
standard form of equation is x² + 7x - 18 = 60 .....................1
it will be
x² + 7x - 78 = 0
(s+13) (s-6) = 0
so that here x = -13
and x = 6
here we Discard x = -13 because the side length cannot be negative.
so x = 6
and area of the original square = 36 in²
The diagram shows a trapezoid prism.
The area of the cross-section is 55cm.
The volume of the prism is 330cm
Find the length of the prism.
Answers
Given:
The area of the cross-section is 55cm².
The volume of the prism is 330cm³.
To find:
The length of the prism.
Solution:
We have,
Area of the cross-section = Area of base = 55 cm²
Volume of the prism = 330cm³.
Let x be the length(height) of the prism.
We know that,
[tex]\text{Volume of prism}=\text{Base area}\times height[/tex]
[tex]330=55\times x[/tex]
[tex]\dfrac{330}{55}=x[/tex]
[tex]6=x[/tex]
Therefore, the length of the prism is 6 cm.

Xavier starts the summer with $315 in his savings account. Since he will be working a lot this summer, he made plans to deposit $80 into his account each week. If he ended the summer with $955 in his savings account, how many weeks did he make deposit?
Answers
Answer: 8 weeks
Step-by-step explanation:
He originally had $315 in his account. This figure increased to $955. It therefore increased by:
= 955 - 315
= $640
If he deposited $80 every week, the number of weeks it would take to deposit $640 is:
= 640/80
= 8 weeks

There are 520 marbles in a jar. The ratio of red to yellow marbles is 3:4 and the ratio of yellow to blue marbles is 2:3. What is the total number of yellow and blue marbles?
Answers
Answer:
Step-by-step explanation:
Change the 2/3 to 4/6
Now the ratio becomes 3:4:6
So the number of each is
3x + 4x + 6x = 520
13x = 520
x = 40
Red = 3*40 = 120
Yellow = 4*40 = 160
Blue = 6 * 40 = 240
Total = 520

ABCD is a parallelogram. Find the value of x, y, w, and z.
Answers
Answer:
Summary:
The value of x = -14The value of y = 18The value of w = 14The value of z = 14Step-by-step explanation:
Given
The parallelogram ABCDAD = x-28BC = 3xAB = 12CD = 2/3yWe know opposite sides of a parallelogram are equal.
Therefore,
AD = BC AB = CDnow subtitute AD = x-28 and BC = 3x in AD = BC
AD = BC
x-28 = 3x
switch sides
3x = x-28
subracting x from both sides
3x-x = x-28+x
2x = -28
divide both sides by 2
2x/2 = -28/2
x = -14
Therefore,
The value of x = -14
Now subtitute AB = 12 and CD = 2/3y in AB = CD
AB = CD
12 = 2/3y
switching sides
2/3y = 12
y = 3/2 × 12
y = 18
Therefore,
The value of y = 18
We also know that the opposite angles of a parallelogram are equal.
Therefore,
5w = 70°
divide both sides by 5
5w/5 = 70°/5
w = 14
Therefore,
The value of w = 14
We know that the sum of the measures of the adjacent angles of a parallelogram is 180°.
Here,
m∠B = 70°.
m∠A = (3w+2z)°
As m∠B is adjacent to m∠A.
so
m∠A + m∠B = 180°
so substituting m∠B = 70° and m∠A = (3w+2z)° in the equation
70° + (3w+2z)° = 180°
now substituting w = 14 in the equation
70° + (3(14) + 2z)° = 180°
70° + (42+2z)° = 180°
70° + 42 + 2z = 180°
112 + 2z = 180°
2z = 180° - 112
2z = 68
divide both sides by 2
2z/z = 68/2
z = 34
Therefore,
The value of z = 14

The value of x = -14The value of y = 18The value of w = 14The value of z = 14A shipping box has the dimensions shown 1/4 1/4 and 1/2, What is the volume of the box in cubic yards.

Billy likes to go cycling. His bike has wheels of the diameter 70 cm. He has a counter on his bike which counts the number of revolutions of the wheels make. One day the counter shows 190 revolutions. How far has Billy cycled? Give your answer to the nearest meter.
Answers
Answer:
401 meters
Step-by-step explanation:
To change the units without changing the value, we use the Multiplicative Identity (that is, 1).
The formula for the circumference of a circle is: C=Πd
The problem gives d=85 cm, so C=85Π cm. So, (1 revolution)=(85Π cm)
or 1= (85Π cm) / (1 revolution)
Billy traveled:
150 revolutions
(150 revolutions)*1
(150 revolutions) * ( (85Π cm) / (1 revolution) ) [note: revolutions cancel, leaving only cm]
(150)*(85Π) cm
40055.27 cm * ( (1 meter)/(100 cm) )
401 meters (rounded to nearest meter)
