45 / -15 x 3
45/ -45
-1
Answer: Option 4: -2sin(x + pi/2) - 1
Step-by-step explanation:
When this equation is graphed, the y-intercept is -3 which is what the image shows. None of the others have a y-intercept at -3.
Hope this helps!
On what i need to see what you are talking bout so maybe i can answer it thank u please
Answer:
Refer below explanation.
Step-by-step explanation:
Given : two triangles ∆QPK and ∆LMK.
We have to show ∆QPK ≅ ∆LMK.
Two triangles are similar if ratio of the corresponding sides are equal and measure of corresponding angles are equal.
Statement 1)
QK=16, PK=26, MK=65, KL=40 ( Reason: Given)
Statement 2 )
![\frac{QL}{KL}=\frac{16}{40} \\\\\frac{PK}{KM} =\frac{26}{65}](https://tex.z-dn.net/?f=%5Cfrac%7BQL%7D%7BKL%7D%3D%5Cfrac%7B16%7D%7B40%7D%20%5C%5C%5C%5C%5Cfrac%7BPK%7D%7BKM%7D%20%3D%5Cfrac%7B26%7D%7B65%7D)
(reason : ratio of corresponding sides)
Statement 3)
![\frac{QL}{KL}=\frac{16}{40}=\frac{2}{5} \\\\\frac{PK}{KM} =\frac{26}{65}=\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7BQL%7D%7BKL%7D%3D%5Cfrac%7B16%7D%7B40%7D%3D%5Cfrac%7B2%7D%7B5%7D%20%5C%5C%5C%5C%5Cfrac%7BPK%7D%7BKM%7D%20%3D%5Cfrac%7B26%7D%7B65%7D%3D%5Cfrac%7B2%7D%7B5%7D)
Thus, ![\frac{QL}{KL}=\frac{PK}{KM} =\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7BQL%7D%7BKL%7D%3D%5Cfrac%7BPK%7D%7BKM%7D%20%3D%5Cfrac%7B2%7D%7B5%7D)
(reason: simplify ratios)
Statement 4)
∠MKL = ∠PQK (reason : Vertically opposite angles)
Statement 5)
∆QPK ≅ ∆LMK (reason : Side-angle-side)
Side angle side similarity criterion states that two angles are similar if the ratio of their corresponding sides and angle between these sides are equal then triangles are similar.
