Answer:

A, 26

Step-by-step explanation:

Since the area of a triangle is one half base times height, and we have our height as 4, and our base as 13, we get 1/2 * 13 * 4, which is equal to 13 times 2, which is 26. Thus, our answer is A, 26.

Answer:

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = 13 and h = 4 , thus

A = $\frac{1}{2}$ × 13 × 4 = $\frac{1}{2}$ × 52 = 26 units² → A

I have a geometry test I’m gonna fail. If you know any of these answers please put the number of the question,than the answer. I

Answer:

Step-by-step explanation:

20) Angles 1 and 2 are supplementary angles( sum of angle 1 and angle 2 is 180 degrees)

21) Angles 1 and 2 are supplementary angles( sum of angle 1 and angle 2 is 180 degrees)

22) Angle TUW + Angle WUV =Angle TUV

Therefore

(7x-9) + (5x - 11) = (9x+1)

7x-9 + 5x - 11 = 9x+1

7x +5x-9x =1 + 11 + 9

3x = 21

x = 21/3= 7

23) GEF - 13 = 5DEG

and DEF = 149 degrees

GEF = 5DEG + 13

Sum of angles (GEF + DEG)=DEF

Therefore,

DEG + 5DEG - 13 = 149

6DEG = 149 + 13 = 162

DEG = 162/6 = 27

GEF = 5DEG = 27 × 5 =135

24) 7x - 1 + 6x -1 = 180(sum of angles in a straight line)

13x-2 = 180

13x = 180+2 = 182

x = 182/13 = 14

25) 5x + 4 + 8x - 7 = 180( sum of supplementary angles is 180)

13x = 180+7-4= 183

x = 183/13 = 14.08

What is the center of the equation (x+12)^2 + (y-9)^2= 35

Reil [10]

Answer:

(-12,9)

Step-by-step explanation:

The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point on the graph.

Therefore, in the equation (x+12)^2 + (y-9)^2 = 35, the center point on the graph would be (-12,9).

I need help finding the mean, median, and mode(s) I need help with number 7

natta225 [31]

Answer:

the mean is 57.5 the median is 44.5 and the mode is 47

Step-by-step explanation:

the mode is 47 cuz it appeared twice. the median is 57.5 bc 47+147+24+47+38+42=345 and 345/6 is 57.5

Primitive function for:<br><br> 1. f(x)=4e2x+e−x, sådan att F(0)=2

Free_Kalibri [48]

The primitive function for $f(x) = 4e^{2x} + e^{-x}$ is given by it's indefinite integral.

To calculate it, recall:

$\frac{d}{dx}e^{ax}=ae^{ax}$

$\int c f(x)dx = c\int f(x)dx$

Let's begin

$\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1} + c\\$

$F(x) = 2e^{2x}-e^{-x} +c$

To find the costant, we just need to use the fact that $F(0)=2$

$F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3$

Therefore,

$\boxed{F(x) = 2e^{2x} - e^{-x} -3 }$
