what is the area of triangle DEF
Answer: 588 centimeters
Answer:
C: 588 square centimeters
Step-by-step explanation:
A= 1/2(b)(h)
base: 42
height: 28
A = 1/2(42)(28)
A = 1/2(1176)
A = 588
Jada has a sleeping bag that is rated for 30° F. This means that if the temperature outside is at least 30° F, Jada will be able to stay warm in her sleeping bag. Let t represent the temperature in degrees Fahrenheit.
Answer:
30-70 degrees F Actually read my response because it explains
Step-by-step explanation:
Well if the outside air is 30 degrees F and the rated temp. for the sleeping bag is 30 then the temp. for the sleeping bag has to be anywhere from 30 and up. Probably like 30 through 70. I didnt really know what the question was because you didn't really make it clear but I tried my best. :)

The graph of y= f(x) is shown below. What is the value of f(-3)
The value of the function at x = -3 is -1
What is function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.
Given that a graph of y= f(x), we need to find f(-3)
The graph tells the value of y when x = -3 is -1
Hence, The value of the function at x = -3 is -1

y=x+3 Solve the system of equations by graphing.
two congruent, isosceles triangles are joined to create a parallelogram. the largest angle of the parallelogram is 116.
write two equations
solve them to find the value of a and b
Answer:
4 a + 2b = 360 ----->equation 1
a + b = 116 --------> equation 2
a = 64 °
b = 52°
Step-by-step explanation:
The sum of all of the internal angles would be 360°. Since we have four "a"s and two "b"s, we have:
4a + 2b = 360
Then told that the largest internal angle of the parallelogram is 116 degrees, so:
a + b = 116
We now have a system of two equations and two unknowns.
I'll simplify the first equation by dividing both sides by 2, then multiplying the second equation by -1 to prepare for solving by elimination:
2a + b = 180
-a - b = -116
---------------------- Add the equations together to get:
a = 64°
Now we can solve for b:
a + b = 116
64 + b = 116
b = 52°
So the values of "a" and "b" are:
a = 64° and b = 52°

in the year 2002 Andrew was on vacation for 7 months out of the year. What percent of the year did Andrew vacation?
Answer:
2009
Step-by-step explanation:
2002+7
=2009
Answer:
58.3%
Step-by-step explanation:
Okay, so we know that there are 12 months in a year, and so we need to find what percent 7 is out of 12, so we divide:
7 ÷ 12 = 0.583
0.583 x 100 = 58.3
So, Andrew was on vacation for 58.3% of the year

Answer:
1. y=ax^2+bx+c, where a,b, and c are real numbers and a doesn't equal zero
2. Parabola
3. Opens upward
4. Opens downward
5. Vertex
6. Axis of Symmetry
7. Zeros, roots, or x-intercepts
8. You are already given the function so
Step 1: FInd Axis of Symmetry
Equation for Axis of Symmetry: x= - b/2a
Step 2: Find Vertex
- The vertex will be on the Axis of Symmetry, so plug in x then find y.
Equation for Vertex: Ex. The vertex is (-5) which is x now we find y by plugging in -5 whenever we see an X. f(x) = -(-5)^2 - 10(-5)-25=0 our vertex would be (-5,0)
Step 3: Draw your coordinates plane and "dash in" the axis of symmetry. Then plot your vertex
Step 4: Plot your y-intercept and the point symmetrical to it. The y-intercept is "c"
Step 5: Find at least other point on the parabola and draw the curve.
sum of the first nth term of a series is given by Sn = n (3n-4). Show that the terms of the series are in arithmetic progression
Answer:
see explanation
Step-by-step explanation:
Using the sum to n terms formula, then
S₁ = 1(3 - 4) = 1(- 1) = - 1 ⇒ a₁ = - 1
S₂ = 2(6 - 4) = 2(2) = 4, then
a₂ = S₂ - S₁ = 4 - (- 1) = 4 + 1 = 5
S₃ = 3(9 - 4) = 3(5) = 15, then
a₃ = S₃ - S₂ = 15 - 4 = 11
S₄ = 4(12 - 4) = 4(8) = 32 , then
a₄ = S₄ - S₃ = 32 - 15 = 17
S₅ = 5(15 - 4) = 5(11) = 55 , then
a₅ = S₅ - S₄ = 55 - 32 = 23
The first 5 terns of the series are
- 1, 5, 11, 17, 23
There is a common difference (d) between consecutive terms
d = 5 - (- 1) = 11 - 5 = 17 - 11 = 23 - 17 = 6
Thus the series is in arithmetic progression

My cousin is scared to talk to the boys at our party cus she thinks even though they are related they are mean. Should she go back there and talk to them, or should me or cousin 2 go with her.
Answer:
Don't force her let her ease into maybe getting comfortable enough to talk to the boys. Give some encouraging words for moral support but don't push it and don't go on your own without her. There will be plenty of more times to talk to different boys. Hope you have a great party.

The graph shows the progress of a train travelling between cities.
a) How far does the train travel in the 4 hour journey?
b) Write down a unit rate which compares the distance travelled with the time taken.
Answer:
a) 240 km
b) 60 km in 1 hour
Answer:
A) It will take 4 hours to get to a distance of 240.
B) If we find the unit rate of 240 by 4, divide 240 by 4, which is 60.
Step-by-step explanation:
A) Look at the graph, you see the dot is left by 240 and down by 4. So it would take 4 hours to get to a distance of 240.
B) Like I said, we divide 240 by 4. Make sure to put 1 as the denominator, and divide the top and bottom by 4.

Without using technology, describe the end behavior of f(x) = 3x32 + 8x2 − 22x + 43. (2 points)
Answer:
This function is an even-degree polynomial, so the ends go off in the same directions, just like every quadratic I've ever graphed. Since the leading coefficient of this even-degree polynomial is positive, the ends came in and left out the top of the picture, just like every positive quadratic you've ever graphed. All even-degree polynomials behave, on their ends, like quadratics.

Answer:
f(4) = 5
Step-by-step explanation:
functions are represented by f(x), so x should be the value in parenthesis and the y value should be what it equals

Answer:
[tex]2\frac{7}{24x} + 5\frac{5}{6}[/tex]
Step-by-step explanation:
[tex]2 \frac{1}{8x}+ \frac{3}{4x} + \frac{1}{6} - \frac{7}{12x} + 5\frac{2}{3}[/tex]
find a common denominator for the x values: GCD = 24
so multiply each fraction with an x to get the common denominator
[tex]2 [(\frac{3}{3} )(\frac{1}{8x})] + [(\frac{6}{6})(\frac{3}{4x})] + \frac{1}{6} - [(\frac{2}{2})(\frac{7}{12x})] + 5\frac{2}{3}[/tex]
then multiply it out
[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5\frac{2}{3}[/tex]
then, find the GCD for the fractions without x: GCD = 3
[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5[(\frac{2}{2})( \frac{2}{3})][/tex]
then multiply it out
[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5\frac{4}{6}[/tex]
finally, combine like terms:

HOPE IT'S HELPTim runs 2.3 miles in 11.2 minutes. If he runs 98 minutes, about how many miles will he run?
Answer:
20.125miles
Step-by-step explanation:
If Tim runs 2.3 miles in 11.2 minutes, then;
2.3 miles = 11.2mins
To determine Tim's distance if he runs 98mins;
x miles = 98min
Divide both equations
2.3/x = 11.2/98
11.2x = 2.3 * 98
11.2x = 225.4
x = 225.4/11.2
x = 20.125
Hence the must have ran 20.125miles
